    Should We Kill The Architecture Review Board?

    • 4 Comments

    OK… I’ll say it.  The whole idea of an Architecture Review Board may be wrong-headed.  That officially puts me at odds with industry standards like CobiT, ongoing practices in IT architecture, and a litany of senior leaders that I respect and admire.  So, why say it?  I have my reasons, which I will share here.

    CobiT recommends an ARB?  Really?

    The  CobiT governance framework requires that an IT team should create an IT Architecture board.  (PO3.5).  In addition, CobiT suggests that an IT division should create an IT Strategy Committee at the board level (PO4.2) and an IT Steering committee (PO4.3).  So what, you ask?

    The first thing to note about these recommendations is that CobiT doesn’t normally answer the question “How.”  CobiT is a measurement and controls framework.  It sets a framework for defining and measuring performance.  Most of the advice is focused on “what” to look for, and not “how” to do it.  (There are a couple of other directive suggestions as well, but I’m focusing on these).

    Yet, CobiT recommends three boards to exist in a governance model for IT.  Specifically, these three boards. 

    But what is wrong with an ARB?

    I have been a supporter of ARBs for years.  I led the charge to set up the IT ARB in MSIT and successfully got it up and running.  I’m involved in helping to set up a governance framework right now as we reorganize our IT division.  So why would I suggest that the ARB should be killed?

    Because it is an Architecture board.  Architecture is not special.  Architecture is ONE of the many constraints that a project has to be aligned with.  Projects and Services have to deliver their value in a timely, secure, compliant, and cost effective manner.  Architecture has a voice in making that promise real.  But if we put architecture into an architecture board, and separate it from the “IT Steering Committee” which prioritizes the investments across IT, sets scope, approves budgets, and oversees delivery, then we are setting architecture up for failure.

    Power follows the golden rule: the guy with the gold makes the rules.  If the IT Steering committee (to use the CobiT term) has the purse strings, then architecture, by definition, has no power.  If the ARB says “change your scope to address this architectural requirement,” they have to add the phrase “pretty please” at the end of the request.

    So what should we do instead of an ARB?

    The replacement: The IT Governance Board

    I’m suggesting a different kind of model, based on the idea of an IT Governance Board.  The IT Governance Board is chaired by the CIO, like the IT Steering committee, but is a balanced board containing one person who represents each of the core areas of governance: Strategic Alignment, Value Delivery, Resource Management, Risk Management, and Performance Measurement.  Under the IT Governance Board are two, or three, or four, “working committees” that review program concerns from any of a number of perspectives.  Those perspectives are aligned to IT Goals, so the number of working committees will vary from one organization to the next.

    The key here is that escalation to the “IT Governance Board” means a simultaneous review of the project by any number of working committees, but the decisions are ALL made at the IT Governance Board level.  The ARB decides nothing.  It recommends.  (that’s normal).  But the IT Steering committee goes away as well, to be replaced by a IT Steering committee that also decides nothing.  It recommends.  Both of these former boards become working committees.  You can also have a Security and Risk committee, and even a Customer Experience committee.  You can have as many as you need, because Escalation to One is Escalation to All.

    The IT Governance board is not the same as the CIO and his or her direct reports.  Typically IT functions can be organized into many different structures.  Some are functional (a development leader, an operations leader, an engagement leader, a support leader, etc.).  Others are business relationship focused (with a leader supporting one area of the business and another leader supporting a different area of the business, etc.).  In MSIT, it is process focused (with each leader supporting a section of the value chain).  Regardless, it would be a rare CIO who could afford to set up his leadership team to follow the exact same structure as needed to create a balanced governance model.

    In fact, the CIO doesn’t have to actually sit on the IT Governance board.  It is quite possible for this board to be a series of delegates, one for each of the core governance areas, that are trusted by the CIO and his or her leadership team. 

    Decisions by the IT Governance board can, of course, be escalated for review (and override) by a steering committee that is business-led.  CobiT calls this the IT Strategy Committee and that board is chaired by the CEO with the CIO responsible.  That effectively SKIPS the CIO’s own leadership team when making governance decisions.

    And that is valuable because, honestly, business benefits from architecture.  IT often doesn’t.

    So let’s consider the idea that maybe, just maybe, the whole idea of an ARB is flawed.  Architecture is a cross-cutting concern.  It exists in all areas.  But when the final decision is made, it should be made by a balanced board that cares about each of the areas that architecture impacts… not in a fight between the guys with the vision and the guys with the money.  Money will win, every time.

    Analysis, Synthesis, and Scope: Business Architecture vs. Business Analysis, part two

    • 4 Comments

    A few days ago, I quickly dashed off a post on the difference between a business architect and a business analyst.  The reaction was immediate and rather vociferous.  The IIBA took me to task for saying that a business architect is NOT a business analyst.  In addition, Tom Graves (Enterprise Architect) asked me to consider the possibility that the two roles are primarily different in another way, altogether.  Tom asked me to consider the possibility that an architect role is primarily one of synthesis (putting things together), while an analyst role is one of analysis (taking things apart).  I beg to differ.  This post included my thoughts on that distinction.

    Graves’ trilogy: Analyst-Anarchist-Architect

    Tom has pointed out, in past articles, that there is real value for enterprise architects to consider the Hegelian triad of Thesis-Antithesis-Synthesis.  In his post, Tom presents a triad, based on Hegelian thinking, three different roles in sequence: business analyst – business anarchist – enterprise architect.

    In Tom’s thinking, the analyst is good at creating an initial hypothesis that represents incremental improvement… at doing things right.  The anarchist is the role that questions the assumptions underlying the analysis.  It is the role of anarchist to test those assumptions, and make sure that they do indeed align with the real world of “trial, error and experience”.  The anarchist prevents us from accepting our assumptions.  The architect puts it all back together.  According to Tom Graves:

    And the architect role is about bringing it all together again. It’s the ‘synthesis’ part of the triad; but it’s also about the Concrete, about making things real, being effective – about doing the right things right in a concrete, practical way.

    Here is where I have to take my hat off to Tom.  There is a very important thought process going on here, and one that I both agree with and can immediately use.  I admit to not having taken the time to really grok Tom’s post prior to now, but I couldn’t agree more with the thinking process.  You have to form an initial idea, then break apart the assumptions in order to test the initial idea, and lastly bring it all together in a solution that actually works.  It’s an excellent approach.

    Shouldn’t this kind of thinking simply be a template for each individual person?  Shouldn’t one person perform all three activities?  Tom addresses this as well.

    One way to resolve the architecture of that architecture is to have just one person doing all of those roles – after all, they’re different roles, not necessarily different people. But that can sometimes be quite a ‘big ask’, because each of the roles does demand different skillsets, different paradigms, even different worldviews – again, somewhat tricky.

    Tom suggests that it is difficult for one person to perform all three, and that large organizations (and large markets) may have the freedom to separate out the roles into different people.  It’s an interesting idea, but I don’t know if provides the clarity I’m looking for.

    I believe that Tom is completely right in one respect.  Solving a problem effectively requires that you go through stages of thinking.  If you simply look at the problem and conceive of a couple possible solutions, you could just as easily fail to consider the optimum one (not on the list), or choose the wrong solution (whatever “wrong” means).  In order to reach the best possible decision, you must go through the additional steps of antithesis and synthesis. However, I don’t think that this distinction is sufficient to explain and position the roles of Business Analyst and Business Architect. 

    The process of thinking through a problem applies to ALL roles that solve problems (a fairly long list).  It doesn’t just apply to business analysis.  Following the path from thesis to antithesis to synthesis is an art practiced by artisans, craftsmen, mathematicians, scientists, engineers, leaders, managers, and politicians.  It is best practice for all of human thought, and not just one area of human endeavor.  Everyone who thinks, and considers, and solves, should use all three steps.  To use Tom’s terminology, each person should be an analyst, an anarchist, and an architect.

    Different Efforts, Different Results

    Tom’s thought process is excellent, but I don’t believe it answers the core question.  Over the past few years, we’ve seen the emergence of two different “job titles.”  Both jobs emerged out of the need for the information technology division to address business problems in new and novel ways.  The core question that I’d like to address is simple: is this something that one person does, or something that two people do?  Are we more effective, and efficient, to separate the roles and responsibilities?

    Some things we all agree on.  The business analyst role is much more tactical than the business architecture role.  Traditionally, the business analyst is required to understand the problems of a business area and to document the requirements of the business in solving them.  The business analyst is NOT accountable for developing the solution, or even the vision for the solution (The solution architect does that).  He or she is accountable for understanding the problem and documenting the requirements that the solution must meet.

    The business architect role is a more recent innovation.  This role emerged out of the need to insure that departments and divisions are using IT resources correctly by asking for the right problems to be solved.  From there, the role has expanded to a non-IT-focused value proposition.  The business architecture role is important.  Without the business architect involved, we may do an excellent job of solving problems that the overall enterprise does not need solved, when the real enterprise-level problems are going unaddressed or under-resourced due to the long list of demands from the existing businesses.

    The business architect is different from the business analyst because he or she is fundamentally charged with four different responsibilities:

    1. understanding the actual enterprise-level needs and the relationship between one business area in respect to the overall strategies,
    2. partitioning the services that one business area should produce and the needed level of maturity for those services,
    3. creating a vision of those services, from the perspective of the business, and
    4. insuring that it aligns to the actual and proposed architecture of the business as a whole. 

    Note that (2) occurs rarely… only when major changes to the business models themselves occur. 

    Some analysis will perform responsibilities (1) and skip to (3).  In most cases, that works.  On the other hand, performing responsibilities (2) and (4) requires the skills of an architect.  There are two different skill sets here.  Can one person do both?  Yes.  Should they?  That depends.

    As these roles continue to mature, we need to either carve out distinctions, or merge them into a single role. 

    Business Analyst and Business Architect as one person

    In my prior post, I made the case that there are many differences between a business analyst and a business architect.  My prior post was based on the assumption that there needs to be two different people playing these roles.  That assumption is NOT valid in all cases. 

    There are many situations where it makes a great deal of sense for the activities of business architecture and business analysis to be performed by ONE individual for financial and logistical reasons.  For example, if the IT unit in question has a small set of responsibilities, or if we are talking about a medium-to-small business (or business area), there just isn’t enough work to keep two different people employed full time in complementary roles.  Within my company (Microsoft), there are some smaller areas of the business that are covered by one individual who performs both business architecture and business analysis tasks.

    The question that I have, however, is simple.  While it is possible for one person to perform two jobs, does that mean there SHOULD be one job?  Should we merge the roles so that every business analyst should be an architect, and every business architect should be an analyst?

    Business Analyst and Business Architect as complementary roles

    Regardless of what we want to happen, reality is going to keep getting in the way.  Both roles exist.  Sometimes they intersect.  The real challenge comes when two people have to play complementary roles, one as a business architect, and the other as a business analyst.  In larger organizations where business architects are appearing as independent roles, and in situations where consultants are being hired, this situation is increasingly common. 

    In order to be effective, these two folks need to have clear accountabilities.  They need to be clearly supporting the success of one another, but able to succeed independently of one another (the failure of one cannot prevent the success of the other).  In order to meet these criteria, there is one very important distinction.  Both must have a different set of problems to solve, and both must have the full scope to solve those problems.  Both must perform the three steps of emergent thought that Tom points out: thesis, antithesis, and synthesis… or analyst, anarchist, and architect. 

    There is no good source, in existence, for clarifying those accountabilities.  The Business Analysis BOK focuses on skills and methods, not accountabilities.  The Business Architecture BOK focuses on different skills and methods, but not accountabilities.  Both fields seem happy to simply overlap.  That is probably OK from the perspective of describing the fields.

    However, in an actual organization, where people have jobs to do, more clarity is required.

    Conclusion

    No matter how we reconcile these two roles, we need to understand that the growth of business architecture will not be abated just because the profession of business analyst has laid a moral claim to the activities that business architects have decided to focus on.  Rather than argue about whether business architects are, first and foremost, analysts, lets look at whether we can address two key questions:

    a) Is it better or worse for these roles to be independent?

    b) When both roles exist in the same organization, how do we prevent confusion, clarify accountabilities, and make both roles effective?

    Arguments don’t matter.  Answering these questions… that matters.

    The difference between business architect and business analyst

    • 14 Comments

    [Author’s note: within an hour of posting the following article, Kevin Brennen of the IIBA dry-roasted the post on his own blog.  You can find a link to his entry here: Business Architecture is Business Analysis.  I have made an attempt to fix a few of the most egregious errors in the post, and to follow up with an addendum (below).]

    One distinction that I believe we should make, as the field of business architect takes hold, is the difference between a business architect and a business analyst.  There are real opportunities for confusion here.  In addition, there are some folks who believe that there is a good career growth path from business analyst to business architect.  In this post, I will provide my opinions about the relationship.

    Definitions

    Business Architect – A role within various types of enterprises (business, government, non-profit) that is focused on collecting information on the strategic positioning of an area of activity (line of business, business unit, department, team, etc.) and creating a clear picture of the capability gaps that may impede that area from reaching it’s full and required potential.

    Business Analyst – A role either within an information technology division of an enterprise, or within a non-IT team serving as a key point of contact with an IT division.  This role is focused on understanding the root cause of a specific business problem in order to develop the IT requirements needed to address that problem.

    (Inevitably, someone will ask me where I got those definitions.  I made them up.  I reserve the right to be wrong.)

    Comparison

    Both of these fields analyze the business… but that is where their similarities end.  Let me repeat that: Business Architects analyze the business.  Business analysts analyze the business.  

      Business Architect Business Analyst

    What Business motivational models, Value Streams, Scenarios, Capability models, Heat Maps, Funding Maps, Risk maps Business Requirements, Business Rules, Use Cases, and Detailed Business Process descriptions

     

    Perhaps this simple table will do a good job of explaining why these roles are different.  If you look at the people and their skills, there is some overlap.  Certainly, smart people with excellent analysis skills can do many things.  But we are not talking about the people.  We are talking about the actual role.  There is nearly nothing about these roles that are actually the same.    These are fundamentally different roles.  Yes, there are people who can play both roles.  (One of the software developers I hired at Acadio had a degree in archeology.) 

    In fact, I have never seen a business analyst successfully transition to the role of business architect.  Note that this is my personal experience, and I am willing to consider that there are many folks who have made that transition.  I have watched many struggle, and fail, on that road.  Given what I’ve seen, I consider this a very difficult transition.

    I am not going to make a lot of friends with this post.  I respect that.  Just sharing my opinion and my experience.  Hopefully, I haven’t lost friends along the way.

    [Follow-up note from Nick: I have met Kevin as well, and I respect the work that he has done, especially on the BABOK.  His blog post responding to this one was not a big surprise in hindsight.  However, I hadn’t expected such a complete rejection of the points.  So I took a few minutes to review the BABOK v2 document.  I hadn’t noticed this aspect of the guide before… guess I hadn’t been motivated enough to think about it: the BABOK defines the tasks of Business Analysis, not the role of Business Analyst. 

    To whit, the BABOK v2 specifically states:

    “A business analyst is any person who performs business analysis activities, no matter what their job title or organizational role may be. Business analysis practitioners include not only people with the job title of business analyst, but may also include business systems analysts, systems analysts, requirements engineers, process analysts, product managers, product owners, enterprise analysts, business architects, management consultants, or any other person who performs the tasks described in the BABOK® Guide, including those who also perform related disciplines such as project management, software development, quality assurance, and interaction design.”

    That is a very expansive definition. 

    Let’s put in a terms of a metaphor.  What if the role of “physician” were defined in the same way.  Would it look like this?

    A physician is any person who performs the activities of diagnoses, treatment, surgery, prescription, pharmaceutical distribution, wellness evaluation, or their related activities.  Physicians may include not only people with the job title of physician but also registered nurse, nursing assistant, pharmacist, pharmacy technician, physical therapist, physician’s assistant, psychiatrist, psychologist, chiropractor, personal trainer, and massage therapist or any other person who performs the tasks described in the Physician’s Desk Reference.

    Do you see the problem?  The BABOK itself points out one of the key reasons for defining the profession: to define “the skills and knowledge that people who work with and employ business analysts should expect a skilled practitioner to demonstrate.”  How can an employer expect a specific level of skill if it that bar is so low that a dozen different roles are expected to perform it well? 

    This is a problem with the BABOK, not the analysts themselves.  Including such a wide array of roles in the “definition” of a business analyst creates a situation where no other profession can define a role that cares about similar concerns without overlapping with this definition.  According to this definition, I’ve been a business analyst for 20 years. In fact, I stopped playing the role of business analyst over a decade ago. 

    Here’s a simple test to see if you are a Business Analyst or something else:  if your employer decides to completely erase his IT budget, and spend NOTHING NEW on IT systems, how busy would you be?  If you answer “I’d go to part time” then you are sitting squarely on the line between business analyst and some other role. If you answered “I’m out of work,” then you are a full time business analyst.]
