TechTarget has published another one of my “Ask the Expert” columns. In this one, I offer up my thoughts on the differences between a Microservices Architecture and a SOA. In a nutshell, I think the microservices trend has moved things in the right direction, a direction that many of the SOA pundits were espousing back in the mid-2000’s. Regardless of what we were saying, however, there’s no denying that the reality of SOA back then was still more of service enabled architecture then service oriented architecture. Give my thoughts a read, and feel free to post comments and questions in the discussion section over there.
A break from my normal tech-related posts.
In September, I will participating for the second time in the Pedal the Cause bicycle ride in St. Louis. This great event raises money for cancer research at St. Louis Children’s Hospital and the Siteman Cancer Center in St. Louis.
I filled out my rider profile in late June and dedicated my ride to Zac Epplin, my brother-in-law’s nephew. In other words, he is part of my family. Little did I know that on July 1, we would receive news that would make this ride much more personal for me.
Zac was diagnosed in August 2013 after noticing a lump on his side during a soccer practice. Zac’s team went on to win the state championship that year, and despite having just gone through several rounds of chemotherapy, Zac took the opening kickoff of their championship match, even though he could barely stand, let alone walk or run on the soccer field. His teammates wanted him there.
Here’s a story the St. Louis Post-Dispatch ran on Zac during the tournament run.
The community rallied behind Zac, holding several fund raising events to help out with his care. My brother-in-law told me that these events weren’t so much about the money, they were about hope. Each time the community came together, it gave Zac hope. That hope gave Zac strength to keep fighting and to live his life beating cancer. Stuart Scott of ESPN said, “you beat cancer by how you live while you live.” That’s exactly what Zac did.
On July 1st, Zac’s battle with Ewing Sarcoma ended. He was only 19 years old. The Belleville News-Democrat published a great article about him with quotes from his soccer coach and teammates.
So, I am asking all of you to share this post and consider donating to me on my ride, donating to some other cancer charity, or doing anything you can to give cancer patients hope. If you share this, please use the hashtag #ZRideForHope. I’d like nothing more than to see this go viral, so that his family knows that even though Zac’s battle is over, the message of hope will not stop and we will all do what we can to find a cure.
You can donate to Pedal the Cause here. 100% of your donation goes to cancer research.
“I can do all things through Christ who strengthens me.” -Philippians 4:13, Zac’s “watch words” during his battle.
In this article from the Wall Street Journal, author Christopher Mims quotes mobile analytics company Flurry’s data that 86% of our time on mobile devices are spent in apps, and just 14% is spent on the web. While Christopher’s article laments that this is the “death of the web”, I’d like to put a different spin on this. We are now entering the age of what I call the “micro-UI”.
The micro-UI represents a shift toward very targeted user experiences focused on a much smaller set of capabilities. A phrase I’ve used is that we are now bringing the work to the user, rather than bringing the user to the work. It used to be that you only had access to a screen when you were in the den of your house with the desk with the built-in cabinet for your “tower” (why do they still sell those?) with a wired connection to your dialup modem, or your computer on your desk at work. Clearly, that’s no longer the case with smart phones, tablets, appliances, your car, and many more things with the capability to dynamically interact with you. I just saw rumors today about the screen resolution of the new Apple Watch, and I think it has higher resolution than my original Palm Pilot back in the late 90’s. On top of that, there are plenty of additional devices that can indirectly interact through low power bluetooth or other tethering techniques.
In this new era, the focus will be on efficiency. Why do I use an app on my phone instead of going to the mobile web site? Because it’s more efficient. Why do notifications now allow primitive actions without having to launch the app? Because it’s more efficient. It wouldn’t surprise me to even see notifications without the app in the future.
For example, how many of you have come home to the post-it on your door saying “FedEx was unable to deliver your package because a signature is required.” Wouldn’t it be great to get a notification on your phone instead that asks for approval before the driver leaves with your package in tow? But do you really want to have to install a FedEx app that you probably will never open? Why can’t we embed a lightweight UI in the notification message itself?
In the enterprise, there are more hurdles to overcome, but that should be no surprise. First, the enterprise is still filled with silos. If it were up to me, I would ban the use of the term “application” for anything other than referring to a user interface. Unfortunately, we’ve spent 30+ years buying “applications,” building silos around them, and dealing with the challenges it creates. If you haven’t already, you need to just put that aside and build everything from here on out with the expectation that it will participate in a highly connected, highly integrated world where trying to draw boundaries around them is a fruitless exercise. This means service-based architectures and context-launchable UIs (i.e. bring the user to the exact point in the user interface to accomplish the task at hand). Secondly, we need to find the right balance between corporate security and convenience. All of this era of connected devices rely on the open internet, but that doesn’t work very well with the closed intranet. Fortunately, I’m an optimist, so I’m confident that we’ll find a way through this. There are simply too many productivity gains possible for it not to happen.
I believe all of this is a good thing. I think this will lead to new and better user experiences, which is really what’s most important. Unlike Christopher’s article, I don’t see this as the death of the web, as without the web as the backing store for all of this information, none of this would be possible. It is a reduction in the use of a browser-based UI, and he’s correct that there are some good things about the web (e.g. linking) that need to be adapted (app linking and switching) to the mobile ecosystem. On the other hand, however, this increased connectivity present opportunities for higher productivity. Apple (e.g. Continuity), Google, Microsoft, and others are all over this.
Think enterprise first. Such a simple statement, but yet it is so difficult to do. Admittedly, I am an enterprise architect, so it’s my job to think about the enterprise. In reality, it’s not just my job. If you are an employee, it’s your job, too.
Why am I bringing this up? I believe that having a simple, clear statement that embodies the change that we’re looking for is critical for making that change occur. so, when I sat back and thought about my experiences over the years and tried to think of a general, common problem that needs to change, what became clear was the very project-centric culture of most IT organizations.
Projects are necessary to ensure that delivery occurs, but let’s face it, have you ever been on a project where scope was the least flexible thing? From day one, schedule and resources are always less flexible than scope. As a result, we have an IT culture that is obsessed with on-time, on-budget delivery, that will always sacrifice scope.
While schedule and resources will always wind up being the least flexible thing by the end of the project, it shouldn’t begin that way. The change that must occur is to start out thinking “enterprise first.” The simplest example I can think of this is in service development. What’s the behavior in your organization? Do teams build “their” application and only create services where a clear opportunity for reuse exists (or when a governance team forces them to), or do your teams define their projects as services first (regardless of any known opportunities for reuse) and then add in whatever application-specific stuff is necessary. The latter is an enterprise-first thinking, the former is an example of project-first thinking.
The argument you may have is, “isn’t this going to result in bloated , over-engineered solutions?” It shouldn’t. Making something a service doesn’t require surveying the enterprise for requirements. it means we place the proper ownership and management around that service so that it is positioned for change. We can only design to the knowledge that we have based on past experience and known requirements. We can’t predict what changes will come, we can only make sure we are properly prepared for that change. project-first thinking doesn’t do that, enterprise-first thinking does. Think enterprise first.
While I have not yet embarked on writing another book, I have been published in a second book. The publisher of my book on SOA Governance, Packt Publishing, has released their first compendium title called, “Do more with SOA Integration: Best of Packt.” It features content from several of their SOA books and authors, including some from my book on SOA Governance. If you’re looking for a book that covers a more broader perspective on SOA, but has some great content on SOA Governance as a bonus, check it out.
On a related note, I’ve been toying with the idea of authoring another book, this time on Enterprise Architecture. There are certainly EA books on the market, so I’m interested in whether all of you think there are some gaps in the books available. If I did embark on this project, my goal would be similar to my goal on my SOA Governance book: keep it easily consumable, yet practical, pragmatic, and valuable. That’s part of the reason that I chose the management fable style for SOA Governance, as a story is easier to read than a reference manual. If I can find a suitable story around EA, I may choose the same approach. Please send me your thoughts either by commenting on this post, or via email or LinkedIn message. Thanks for your input.
I saw a tweet today, and while I don’t remember it exactly, it went something like this: “You must be successful with SOA to be successful with the cloud.” My first thought was to write up a blog about the differences between infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS) and how they each relate to SOA until I realized that I wrote exactly that article a while ago as part of my “Ask the Expert” column on SearchSOA.com. I encourage you to read that article, but I quickly thought of another angle on this that I wanted to present here.
What’s the first vendor that comes to mind when you hear the words “cloud computing”? I’m sure someone’s done a survey, but since I don’t work for a research and analysis firm, I can only give you my opinion. For me, it’s Amazon. For the most part, Amazon is an infrastructure as a service provider. So does your success in using Amazon for IaaS have anything to do with your success with SOA? Probably not, however, Amazon’s success at being an IaaS provider has everything to do with SOA.
I’ve blogged previously about the relationship between ITIL/ITSM and SOA, but they still come from very different backgrounds, ITIL/ITSM being from an IT Operations point of view, and SOA being from an application development point of view. Ask an ITIL practitioner about services and you’re likely to hear “service desk” and “tickets” but not so likely to hear “API” or “interface” (although the DevOps movement is certainly changing this). Ask a developer about services and you’re likely to hear “API,” “interface,” or “REST” and probably very unlikely to hear “service desk” or “tickets”. So, why then does Amazon’s IaaS offering, something that clearly aligns better with IT operations, have everything to do with SOA?
To use Amazon’s services, you don’t call the service desk and get a ticket filed. Instead, you invoke a service via an API. That’s SOA thinking. This was brought to light in the infamous rant by Steve Yegge. While there’s a lot in that rant, one nugget of information he shared about his time at Amazon was that Jeff Bezos issued a mandate declaring that all teams will henceforth expose their data and functionality through service interfaces. Sometimes it takes a mandate to make this type of thinking happen, but it’s hard to argue with the results. While some people will still say there’s a long way to go in supporting “enterprise” customers, how can anyone not call what they’ve done a success?
So, getting back to your organization and your success, if there’s one message I would hope you take away from this, it is to remove the barriers. There are reasons that service desks and ticketing systems exist, but the number one factor has to be about serving your customers. If those systems make it inefficient for your customers, they need to get fixed. In my book on SOA Governance, I stated that the best way to be successful is to make the desired path the path of least resistance. There is very little resistance to using the Amazon APIs. Can the same be said of your own services? Sometime we create barriers by the actions we fail to take. By not exposing functionality as a service because your application could just do it all internally, in-process, we create a barrier. Then, when someone else needs it, the path of least resistance winds up being to replicate data, write their own implementation, or anything other than what we’d really like to see. Do you need to be successful with SOA to be successful with the cloud? Not necessarily, but if your organization embraces services-thinking, I think you’ll be positioning for greater success than without it.
On the Forrester Enterprise Architecture Community site, Randy Heffner asked the question, “What should EA do for business agility?” In my two responses in the discussion, I emphasized that EA is all about decision support. Yes, you may create a future state roadmap, but what the organization winds up with is completely dependent on what projects the organization decides to execute, and then on how those efforts are executed. EA influences those decisions, but we’re not the ones making them.
So why is this post titled, “Deciding ‘Yes’ on EA”? In that same discussion, William El Kaim added the following:
Let me be real provocative, and state: EA is dead … It has been killed by architect themselves leaving in their ivory tower and their beautiful EA drawing tool that nobody uses and that contains outdated data when they are published.
You can read the rest of what William had to say on the Forrester site, but I don’t think it’s anything any of us practicing EA’s haven’t heard before. But there’s a very important point in William’s statement. If nobody uses what EA produces but EA themselves, that’s a big problem. Put simply, if we provide poor decision support, the organization will ultimately decide against EA.
Like most things in this world, there are far more ways to fail than there are to succeed. So what are some best practices for providing excellent decision support so that the organization will decide “yes” on EA?
- Figure out who makes the decisions. Sounds simple, right? Not quite. I’d love to see a Forrester or Gartner survey on this one, but I’m willing to clarity and consistency on the decision making process is not a strength for most organizations. Regardless of the state of your decision making process, if you don’t have access to the people making the decisions, you have little to no chance of influencing them.
- Figure out how they make their decisions. Note that I didn’t add, “and make them better.” Remember that they’re the one making the decisions, not you. Your role is to give them added information so that they can make the best decisions possible. In some cases, the whole reason for having the discussion may be so you can learn and incorporate that decision maker’s information into your guidance for other decision makers.
- Make your information relevant to them. Don’t give them a bunch of models that are only meaningful to another EA. In the case of upward decisions, this usually means that the architecture implications have to have financial ties, or clearly alignment with business objectives. I’ve had success using capabilities in these discussions, and I think the current research would back that up. You must tailor your information to their needs. If they don’t understand it, it’s your problem, not theirs. They’re making the decision, not you.
- Emphasize added insight, not oversight. This is very important for interactions with project teams. All too often, EA is positioned as the enforcer. Come before the review board and we shall assess your worthiness. I’m sorry, but a guy who spends 80% of his time writing code each day should be far more aware of the latest frameworks than the average EA. The role of the EA is bring enterprise and/or domain perspective to the effort. As soon as the project gets established, the project blinders go up, and it’s the job of EA to remove those blinders and add enterprise insight into the effort.
- Don’t rely solely on artifacts, and where you must, make sure they are easily digestible. While many factors in an organization lead us toward email-based interactions of documents, try to have a face-to-face conversation about the guidance whenever possible. At a minimum, by walking someone through it, you at least knowing they’re actually reading some part of it. When you create the artifacts, get them to the point.
- Be cautious about consulting models for EA.A consulting model for EA is great, right? When someone needs more information to make a decision, what do they do? They hire a consultant. So EA should be internal consultants, right? Well, not really. That may work in the short term, but it is a “I’m here when you need me” model, when you really want to always be a part of the process. Don’t turn down the consulting approach, as it can get your foot in the door, but make sure you turn it to something more systemic.
What other best practices (or worst practices) do you recommend in firmly establishing EA as a valuable resource in the decision making processes in the organization?
Every organization has one. For some, it can lead directly to a path of enlightenment. Others may use its rigid structure to create an impenetrable fortress of strength. For the unfortunate, it becomes an inescapable labyrinth of hopelessness. Yes, it’s the org chart.
Okay, let’s be fair, it’s actually not the chart that’s the real challenge, it’s the organizational structure. Any organizational structure creates boundaries, and those boundaries create opportunity for divergence, whether in strategy, opinions, processes, or just about anything else. The challenge is figuring out how to structure the organization to diverge where you need divergence, but to be consistent where you want consistency. It’s no surprise that organizational structure is considered by some to be part of the enterprise architecture. Just as we try to organize our technology portfolio in the best manner to achieve the desired business goals, we need to organize our human resources as well. More importantly, just as management may choose to reorganize its human resources as the business goals and operating context changes, the way we organize our technology portfolio needs to change as well.
The organizational structure poses a particular challenge for the practice of architecture, particularly when it comes to solution architecture. I’ve seen at least three different models for organizing the architecture practice. First, is the centralized model where all architects report up to a single Chief Architect or Director of Architecture. There may be some middle management in there, but there is always a solid line leading to the top. As you might guess, this usually leads to a high degree of consistency, but can have challenges in scaling to meet demand, retaining business domain knowledge, and of course, ensuring that the centralized resources actually get used by projects and avoiding “rogue architecture.” The overuse of the term “architect” in job titles these days makes this even more problematic, as senior or lead developers may now have the title of Java/.NET Architect. It may also create delays in decision making, because the solution delivery has one reporting structure, while the solution architecture has a different reporting structure. If there is a disagreement, these two management structures must come together to resolve the difference, or it must be escalated up the chain.
A second model is a separation of the Enterprise Architecture function from the Solution Architecture function. Enterprise Architects have a solid line to the Chief Architect/Director of Architecture, Solution Architects report through a different structure, perhaps having a dotted line back into the EA organization in a matrixed structure. Consistency becomes more of a challenge, because Solution Architects will likely receive more direction from their management structure than from the EA team. It also creates challenges for the EA function, because now the EA team is at risk of being completely disconnected from solution delivery. Even in the centralized model, the bulk of the input into the solution comes from the solution management side of things. Now, that push will be even stronger, with architectural management struggling to maintain a voice. That voice is sometimes mandated through an architectural review board, but if that’s the only time that architectural management has the solution architect’s ear, the effort is likely to struggle with EA being seen as an ivory tower, rather than a necessary contributor to solution success. I’ve seen this model more than either of the others, however.
The third model would be the completely decentralized model. In this case, there is still a practice of architecture in the organization, but it is completely distributed. Solution architects, and perhaps domain architects, are scattered throughout the organization. A virtual team may exist, and there may even be a Chief Architect/Director of Architecture, but the role may largely be one of information sharing and coordination, and not really about architecture management. What’s good is that there’s not much risk of being perceived as an ivory tower, but there is significant risk of poor architectural alignment. If the boundaries of diversification are based upon an assumption that business units do not share customers, what happens if the situation changes and they do? Even ignoring the potential for this situation, decisions on centralization versus a matrixed approach are likely made locally within each business unit.
So what model is right? First, a completely decentralized approach is really only suitable for companies with a completely diversified operating model (see this book if you don’t know what that means). So, it really comes down to centralized versus matrixed, and that will either be applied at the business unit level for a diversified company, or at the enterprise level for other operating models. Both centralized and matrixed can work, but there is a catch. I’ve used the term “architecture management” in this blog. As I wrote this, I kept thinking about parallels to project management and a PMO. I’ve seen centralized PMOs where all project managers report into a single organizational group, and I’ve seen decentralized PMOs where individual project managers report into lines of business while a core group of resources that look at things from a portfolio perspective report into a Director of Product Management. The catch is consistency. If each project manager did things their own way, it is going to be extremely difficult for anyone to manage things at a portfolio level. Without establishing some minimum level of consistency that produces the necessary metrics and information at the right times for portfolio level management to happen, you’re sunk. Fortunately, for project management, the need for this is a well accepted practice. No one wants to wait to find out that a project is $100M over budget until after it happens. If you have that consistency, you can make either model work.
In the case of architecture management, things are still maturing. The problem is that we are at risk of focusing solely on consistency, without properly understanding the outcome that consistency is supposed to create. While finding out that you’re $100M over budget after it’s been spent is well understood as a bad thing, is finding out that someone has built a component that already existed elsewhere in the company a bad thing? Not necessarily. Those decisions need to be made in the context of both the project’s goals and the enterprise’s goals to make that distinction. Pursuing enterprise consistency when there are only project goals involved in decision making puts you at risk of being perceived as an ivory tower. At the same time, it may be necessary to pursue some base level of consistency prior to establishing that enterprise context, otherwise the context may be perceived as irrelevant. This can happen when the practice of solution architecture really isn’t being practiced at all.
My final advice is this: a centralized path will definitely lead to the most consistency, but you have to be rock solid in your justification of the need for an enterprise viewpoint, because that centralized model creates management overhead, risk of resource availability, and the potential for conflicting direction. A decentralized model is at less risk of having resource availability issues, but makes consistency more difficult and is more prone to sacrificing enterprise direction for project delivery. Ultimately, it will come down to whether your organization has been successful with matrix management approaches or not. If it has, you should be able to make a decentralized approach work. If you’ve never been successful with matrix management, then a centralized approach will likely be necessary. Finally, if you go with a decentralized approach, but have very inconsistent architecture practices, I strongly recommend that you establish an architecture mentoring/facilitator practice. In this, members of the centralized EA team facilitate one or two day architectural workshops. This can ensure that things are done in a consistent manner, the voice of the enterprise is brought into the solution architecture process, but the risks associated with a completely centralized model are mitigated.
Amazon released their HTML5 Kindle reader this week, and I couldn’t keep myself from commenting on all of the talk of people saying/hoping/proclaiming that this was the beginning of the end for apps and Apple’s AppStore.
I think it’s great that Amazon has released the HTML5 version of the Kindle reader, complete with integration into the Amazon Kindle store. I don’t see Amazon pulling their Kindle app from the app store though, and I think there would probably be a big revolt if they did.
It seems that a lot of the pundits out there think that all of the developers out there are just waiting to jump on a single technology that will support any device, anywhere. For developers that aren’t making any money on their products, that may be the case. I’m willing to bet that the lack of profits has less to do with having multiple code bases to maintain and more to do with the app just not being popular enough.
But all of this isn’t even my main point. To me, the thing that drives it all is customer experience. When the iPhone first came out, everything was Mobile Web. Apple then backtracked, and came out with the App Store. I don’t know about you, but I can’t think of a single App that had a mobile web or iPhone-optimized web experience that was on par with the native apps that were created. Granted, part of that was due to Edge connectivity, but the real thing is that it was all about my experience as a customer. While HTML5 is very powerful, I still don’t believe that it is going to be able to provide the same level of experience that a native application can. Yes, it can work offline and utilize local storage to make it as app-like as possible, but it’s still based on an approach that’s more about a connected, browser-server paradigm.
There will be classes of applications for which HTML5 will be just fine. I’m willing to bet many of them will be replacements for applications that are already free in the app stores. That’s an optimization for the development team, since revenues are clearly coming from another source, whether it be advertising or eCommerce. For paid applications, though, customers are paying for the experience, and if the experience isn’t as optimized as possible, there are way too many alternatives out there.
All we need to do is look back at history to know that Apps are here to stay. Java did not result in companies dropping proprietary development languages for Windows, Mac, or Linux platforms. Yes, some cross-platform products did arrive and continue to thrive, but there’s still a thriving marketplace for native applications on the major desktop platforms. Will we see many mobile applications solely available via HTML5? Absolutely, but the native app store for iOS and Android will continue to thrive.
While I’m sure the last thing we need is another analogy for enterprise architecture, a colleague of mine came up with one that really resonated with me. We were discussing principles, which many believe should represent the shared, unchanging values of the organization, in the context of enterprise architecture and governance. That’s when he came up with this analogy.
Enterprise architects need to work with the enterprise as if it were a family. If you look at a family, especially one with kids, they have their moments, but over time, they all start to embody a set of shared values.
Needless to say, I really liked this analogy. As a parent of three young children, I know exactly what he’s talking about. Now, this isn’t to say that enterprise architects are the parents of the organization, but we do need to be members of the family, more likely to be the wise elders, rather than the crazy uncle or creepy aunt.
What really works with this is that families make mistakes. They’re in a constant state of learning and evolving. Sometimes, as a parent, our goal is to do the exact opposite of something our parents did. Sometimes we want to do exactly the same thing. Most importantly, there are a set of values that we want to install in our children. The easiest path to this is to be an example of those values. We get in trouble when as parents, we contradict those values. The kids will have their moments, because they’re still learning. The same holds true in an enterprise. Individual projects may contradict the values, but it needs to be seen as a learning opportunity rather than strictly a compliance and punishment issue. When the leaders contradict the values or the values are simply unclear, the entire organization is at risk of being dysfunctional.
The role of enterprise architecture is one of ensuring that the enterprise is one big happy family. Sometimes we have to make a sacrifice for one member of the family. Johnny is heading off to college, so perhaps family vacations or other discretionary spending gets cut. While this is really of immediate benefit to Johnny, the decision embodies the family’s values of education. Sometimes Johnny’s little brother Tommy has to wear Johnny’s hand-me-downs. Sometimes we have projects that are of high priority and they get the focus. Other projects may have to reuse things created by other projects. Enterprise architecture needs to be the support for those decisions.
Update: In the twitter conversation that has followed this post, the roles of family therapist and parental guidance have come up. This also came up in my original conversation with my colleague. In my opinion, parental guidance, at least regarding architecture, should be filled by EA and it must be an employee. An outside consultant will never embody the values of the organization, they aren’t a family member. A family therapist, on the other hand, can be provided by a consultant or by an employee. The therapist’s job isn’t to tell you what your values are, their job is to help you identify your own values, and help you identify things where your actions are inconsistent with those values. Normally, if the parents are doing their job, therapy isn’t needed. Parents set expectations up front, and keep an eye out for behaviors that don’t embody the values. If behaviors need correcting, they get corrected through a variety of techniques, whether a carrot or a stick.
I’ve been doing some work recently on architecture principles and their associated implications. According to TOGAF 9’s documentation on architecture principles, implications “should highlight the requirements, both for the business and IT, for carrying out the principle – in terms of resources, costs, and activities/tasks. … The impact to the business and consequences of adopting a principle should be clearly stated.”
In the effort to define our implications, I’ve started to see two categories of implications emerge. The first is behavioral implications. These implications are functions or processes that the organization must adopt. The second is architecture/design implications. To illustrate this, use a very simple principle: standards-based. The statement for this principle merely states that all solutions must be compliant with company standards. A behavioral implications for this is that someone in the company must maintain a list of company standards. Another behavioral standard may be that the company must follow the work of standards organizations relevant to the business. An architecture/design implication would be that messaging interfaces must adhere to published company standards.
I’m finding that it may be worthwhile to explicitly define these categories in documenting the principles. One big reason is to avoid overemphasizing the architecture/design implications. It is very easy to strictly think of implications as the foundation for your assessment framework, but an assessment framework, in my experience, is typically associated with architecture and design reviews. It says nothing about reviewing the behavior of the organization, which all too frequently can be the greater challenge. For example, a reusable service may exist, but it doesn’t get used because the organization “supporting” it may see supporting other consumers as a secondary priority, at best. This isn’t a design issue, it’s a behavioral issue.
One additional thing I’m also considering is how to assess whether or not the thinking behind the implications is correct. If the rationale for a principle is that total cost of ownership will be lower, are we actually measuring whether this winds up being the case based upon our level of adherence to principles and their implications?
How would you categorize your implications? Does this two category breakdown make sense, or are there additional categories needed?
In her IT Business Edge blog titled Enterprise Architecture Paying off at Del Monte, Loraine Lawson writes:
Enterprise architecture (EA) befuddles me. As far as I can ascertain, it began as an IT function, but at some point, it was decided that EA is bigger than IT and really needs to work with the business as a business function. … I’ve had my doubts about EA, even though I’ve written several times about how the discipline can reduce integration work.
I thought I’d respond to these statements from the blog. First, regarding the thought that EA is bigger than IT. While some may argue that the original definition was always about more than IT, it’s certainly true that in practice, the focus was almost always within IT. The reason, however, that it needs to become more of a business function is that IT needs to be a business function, rather than being simply viewed as a support organization where things are thrown over the wall. This is also exactly the reason why Enterprise Architecture is a necessary function.
In a pure support scenario, you do what the customer asks, period. You can try to sway the customer, but that’s a risky proposition. Everything is constrained by the definition of the project. In such a culture, decisions that may be beneficial when viewed from the perspective of multiple projects and multiple systems are extremely difficult to make, because they are outside of the control structure (the project) that governs all of the IT activities.
Coming back to Enterprise Architecture, part of the reason it needs to be viewed as a business activity is to change the decision making process around how IT activities are defined. If this process doesn’t change, then IT can only make the best of the hand it has been dealt. Low level technology decisions, such as servers, operating systems, and programming languages, can be handled solely within IT, but as soon as you get into functionality and capabilities, it becomes far more difficult.
In my opinion, the way to do this is through a practice of portfolio management, which I believe needs to be at the core of an enterprise architecture practice. Portfolio management isn’t a one time application rationalization effort, it’s an ongoing discipline that must be integrated into the decision making process for what activities (projects) take place. I’m not referring to project portfolio management, I’m referring to application portfolio management and technology portfolio management. If we do an effective job of this, we better understand the boundaries and dependencies between the capabilities that need to be provided. By better understanding these, the task of integration becomes easier, because it’s a forethought rather than an afterthought.
It’s surprising that this focus on application and technology portfolio management is such a struggle. After all, concepts of portfolio management are well accepted in the financial world. It is a far more risky venture to just blindly purchase financial products that hot today, rather than taking a structured view of your entire investment portfolio and the goals you wish to achieve. But, alas, IT is a very project-driven culture in most organizations, and it is going to take time to change that. Many organizations have reached a breaking point where a one-time application rationalization effort is taken. If your organization is in this position, however, a one-time effort is only a short term fix. Business leaders must not only fix the current situation but also make the necessary changes to ensure it is does not happen again, and I believe a healthy enterprise architecture practice rooted in a disciple of portfolio management is one of those changes needed.
Panel discussion. Panelists:
Eric Christian, Director of Global Architecture Security at Cummins
Sandy McCoy, Executive Director, Business Architecture, Kaiser Permanente
Michael Balay, AVP, Technology & Operations, Enterprise Architecture, MetLife
Moderator: George Paras
Q: Inspiring an EA team is a challenging activity. If you had one bit of advice to an aspiring EA leader, what would it be?
Sandy: There’s an outward leadership component and an inward leadership component. From the outward perspective, anyone on the team must be a leader. You operate at levels most people don’t. Emotional IQ important, and you have to be able to communicate both with a developer or project manager at one time and the CIO the next. From the inward perspective, your people must be empowered and encouraged. EA is a thankless job, you must know when your staff is having a bad day.
Eric: We have a tremendous opportunity to add value. Focus on delivering it incrementally. Focus on delivering high value in a way that the business community can embrace.
Michael: Leadership matters in every aspect of business, especially for the EA organization. Every staff member must be a leader. One of the most important things to do at each stage of transforming is to find leaders to partner with elsewhere in the organization.
Q: As a leader, when you’re looking to incrementally grow your team, what skills do you look for?
Michael: It’s about a team and having a balance of skills. I look for people with both operational and architecture skills.
Sandy: We have a minimum of 15 years of experience, through various tracks within IT to have a variation in the skill set. When you start getting into business architecture, some business acumen is becoming more and more critical. Technology is just built into the business, we are part of the DNA.
Eric: Strongest architects as of late have knowledge of the business. It’s easier to teach an architect to be an architect than to teach them the business in a particular industry.
Q: Where do architects with business acumen come from?
Eric: At Cummins, we have been looking at horizontal immersion programs. They take a horizontal assignment within the business and will hopefully come back. The same holds true for business staff to take a position within IT for a while.
Michael: The balance is going to shift toward more business architects. I always want that business architect side by side with someone who understands the implementation, though. My bias is to find business people, match them up with someone from IT, and let them learn from each other.
Sandy: One skill that I would add to the list is abstract thinking. If you have people that can really think abstractly and connect the dots, then their actual experience is not as critical. Not everyone has this ability.
Q: What size team do you look for?
Sandy: Our chief architect likes to re-organize every 6 months, but his boss tells him to stay stable for a year. You have to adjust to whatever is happening at the time. You need to have a bunch of utility players as well as some heavy hitters in particular areas.
Q: What are the best practices to organization a team?
Eric: Cummins, a couple of years ago had a very decentralized IT. Three years ago, IT was centralized, as where the architects. We have largely aligned along Technology Architecture, Solution Architecture, Enterprise Architecture.
Architecture is an evolution, a maturity process. When you move toward the block and tackle approach, you start with fundamentals (doing well with infrastructure architecture), but as you move up you look at portfolio optimization, etc.
Michael: There is no one model for EA. Almost by definition, it must be designed and tailored to the circumstances of the enterprise. Collaborate with other leaders. Enterprise Architecture must be responding to the strategic events of the company, and may not be able to steadily climb that maturity curve. Groups that do, may be too inwardly focused.
Sandy:If you look at it as a role, rather than an organization, very rarely do we play the role of an Enterprise Architecture. As EA, we can play any of the roles, and we get pulled down into various levels of the architecture depending on the needs of the organization.
Q: How do architects split their time between strategic and tactical work?
Michael: A peer of mine worked on a very successful, strategic architecture for technology integration and services. This year, he’s continuing the effort, but driving down into the implementation of it. At different periods we need different skills.
Michael: This is how things worked at Cummins a year ago. Each of the architects focused on quite a bit. They became spread to thin, weren’t focused on the right things, and the value was marginalized. We made a separation between solution architecture and enterprise architecture to create focus on both areas, and this yielded far more traction.
Sandy: It depends how your mission statement is defined. We have 13 different divisions and they each have a different opinion on what we should be, plus the CIO has another opinion. Set some metrics on what you’d like to do.
Michael: We’re struggling with refocusing. There are too many strategic things out there.
Eric: One of the first things that was negotiated with my boss was the vision and mission. That became the contract. If business partners think something else, we come back to the contract.
Q: How do you demonstrate the value of your EA program? How do you make the investment decision for a tool like Troux?
Michael: We implemented Troux standards in 2-3 months. We were re-instantiating AIG standards. We didn’t have to reinvent the standards, but we did need to reach out to the international community. Traditionally, the review process came very late in the effort. We worked with the PMO to push up the visibility of the project to early in the process, especially so EA had visibility. If managers got involved early, 9 times out of 10, the went through the process very smoothly. We turned the traffic cop into a value proposition.
Eric: We have seen value delivered in a body of analysis work that we have done. Most things have Oracle under the covers. We had our best year ever with an excellent growth trajectory. The value comes into play with trying to balance continued growth of new plants with a strategy for managing the instances of Oracle apps.
Q: What should our audience be paying attention to?
Sandy: Social networking and mobility. People who grew up with it, want and expect collaboration. On the mobility side, everyone wants a little “app” for a piece of the business. Information and data governance becomes much more critical because it is now exposed in places where you may not want it to be.
Eric: Server, app, and desktop virtualization, mobile technology, and SaaS and cloud.
Michael: Mobility, BYOD – bring your own device, Collaboration systems on a new scale, IaaS and virtualization. In the governance space, issue is that we’re already too slow for our customers.
Speaker: Michael Pemberton, Enterprise Architect and USAA
USAA has had an enterprise architecture practice on the technology side and is now establishing a business architecture practice.
First point: Why did USAA take the journey? They realized that without a business-driven, integrated enterprise architecture, it would be like driving without a map.
Their challenge was that they are trying to increase their revenue and the membership, but at the same time, reduce their operating ratio. They needed to reduce the complexity and operating friction within the organization.
For them, being too close to the Enterprise Strategy team was a problem for their Enterprise Architecture team. It may seem counterintuitive, but there are some pressures to keep the strategy team “clean” while the Enterprise Architecture team needed to be out there working with the community.
Models need to be designed to answer questions. The business doesn’t care about the components and representation in the model, they care about the answer to the question they asked. They aim to create visualizations for the enterprise.
USAA Opportunities and Challenges:
- No metamodel, no design!
- Architect architecture
- Business focused architecture
- Visualizations, visualizations, visualizations
- Roadmap capabilities
- Killer curves: supply/demand
They showed a visualization which was essentially a spoked wheel with member at the center of the universe. A layer out from the member was a set of capabilities, then another decomposition to the business level, and then finally a set of processes out in the business. They found the normal “box-in-box” capability view to be unwieldy for the number of capabilities they had.
They also made a commitment to never come to the business with a single taxonomy again. They needed a single taxonomy to do their work, but the business needed to see the results in their own language and taxonomies. They create taxonomy alignment, but they don’t force a single taxonomy on the entire organization.
Principles they use for their visualizations are:
- Use graphics, not words (look up InfoGraphics)
- Show context and meaning NOT context and conclusion
- Enlightenment NOT training
- if you ever show the business your model, you deserve whatever you get – and it won’t be pleasant
- Quit telling executives they should use the tool!
