I always believed that while good architecture skills can be taught, it is the way we think that differentiates us and makes us good architects. Our natural ability to understand the problem and determine the right solution is the magic formula. This – and this alone – distinguishes good architects in our midst. You don't have to have "architect" in your job title or even be in IT to be a good architect. You can understand the technology in minute detail, know all the design patterns, possess tremendous depth of experience, have in-depth knowledge of various design techniques, etc. All this can be taught or acquired. At the end of the day, however, it is your approach to problem solving and the way you think that will make you stand out among your peer architects.
Why do I put such a heavy emphasis on the thinking style? To help you understand, we need to take a step back and define "architecture". According to Wikipedia, "the software architecture of a program or computing system is the structure or structures of the system, which comprise software components, the externally visible properties of those components, and the relationships between them." Many books, articles, and white papers provide a definition of architecture as well. However, in my opinion, these definitions are too complex and do not truly reflect the nature of architecture. My personal definition is very simple: architecture is a high level view of a technical solution to a business problem.
What does the definition of architecture have to do with our approach and thinking style? Everything! Taking all the specifics of how we actually deliver architectural solutions out of conversation, to do our job well we simply need to determine the right technical solution to the right business problem. We need to consider all the possibilities when addressing a business problem – what is there today, what is missing, what problem are we really trying to solve, is the current process the most efficient, what would deliver the most value, are we solving the right problem?.. We should be able to look at the problem from a very high level, abstract ourselves from the underlying technology or processes, and envision the most effective and efficient solution. As in the old adage, we should see the forest for the trees. Once the "ideal" solution is found, we can start concentrating on its details and understanding technology implications. Many times, we will discover that our vision cannot be readily implemented due to technology limitations, insufficient process maturity, and a host of other factors. Do not despair, however. Your vision becomes the solution goal state, and you would need to create a roadmap to get there.
Undoubtedly, some of you will disagree with the approach presented above. I can hear the arguments now – "You must consider the current situation to determine the right solution to the problem", "The project has a limited scope, and thinking broader is impractical", "The technology landscape should be considered upfront to design the most effective solution", etc. However, if we are to find the right technical solution, we must shed the old baggage. It is very hard to find new and innovative solutions if you cannot think outside the current box. To a large extent, the architectural thinking principles are grounded in the definition of what makes a good architect.
Architecture is an art, not a science. Therefore, a good architect is more of an artist – creative, imaginative, someone who can paint with a big brush. In my opinion, the characteristics and approaches listed below are the true differentiating factors among architects.
- Abstract thinking – this is the #1 quality of a good architect. You must be able to see the big picture and understand it abstractly, absent of many details that can cloud your judgment.
- Out-of-the-box thinking – many situations require us to be creative and innovative in our approaches. Good architects should be able to adapt to new situations easily and come up with the right solutions regardless of the situation.
- Clarity of vision – you, as an architect, should be able to clearly envision the solution and all of its implications including business process, technology, low level design, development, and potential phased delivery.
- Strength of convictions – architects should always try to do things right the first time, oppose inappropriate or wrong decisions, and stand up for what they believe are the right architectural solutions.
- Critical thinking – architects should always cast a critical eye towards their domain. You should challenge everything. Nothing should remain status quo or off limits. There are always opportunities for improvement. Don’t miss them because you feel comfortable with the current situation or are used to doing things a certain way.
- Problem solving skills – architects are problem solvers. Good architects strive to solve problems in the minimalist way, i.e. reaching the right solution in the most efficient manner. Even better architects ensure that they are solving the right business problem.
- Soft skills – this one is obvious. Good architects should have excellent soft skills to work well with the diverse audiences they are exposed to every day.
As in the everlasting nature vs. nurture debate, I believe good architects cannot be made – a large portion of what makes architects stand out is ingrained in how we think, act, and approach problems. To be truly effective, we should practice all the elements of architectural thinking and exhibit all the traits of a good architect.
