Solution Architect - Understanding the role

I keep getting questions from some of my friends, as to what the role Solution Architecture is all about and will they be a fit for that role. For the benefit of every one out there, I thought of putting together my thoughts on the role of Solution Architect. Let us first examine what is expected out of this role and then look at the skills needed to be in this role.

As the title indicates very well, the role is expected to bring in solution to varying business problems, most which could be a product or project by itself. But, as you know, it is always a challenge to come up with a best solution due to it being intangible and that there are many quality attributes which are not completely identified and specified. There would be lots of missing links in the areas of business domain, choice of technology, hardware components, business processes, future domain and technology trends, etc  which the Solution Architect should be able to connect and come up with best solution that could last longer, so that the organization reaps the return on investing in the solution.

Some of the key characteristics of a best Software Solution are:

Longivity: While the solution must solve the current business problem, it should also be reliable, usable, secure and also future proof. This means that the solution Architect should consider the industry and technology trends that could have an impact on the problem / solution in the near and longer term.

Trade off: The challenge with the various mostly unspecified quality attributes is that they are interdependent. And meeting one such attributes may most likely mean compromising on another. Obviously, a lot of trade off has to happen between various quality attributes and such trade off should be justifiable in the context of perceived benefits for the organization. For instance, performance may have to be compromised to achieve better security. The tradeoffs have to be carefully made after considering various factors, like the risk appetite of the organization, target users of the solution, the technology platform, current IT investments of the organization, etc.

Implementation view: It is important that the solution should be devised with the intended deployment view into consideration. Without that, it could so happen that the solution as designed and built may call for massive changes to the infrastructure investments, which could be a total surprise for stakeholders. Such surprises emerging towards the close line of the project could increase the cost by manifolds or delay the project further.

The above is not the exhaustive list. There are many other factors that will have to be given due consideration before coming up with the best solution. Above all, the solution architect should be able to see that the solution is successfully implemented and put into use. That means, a lot of work in terms of convincing the stakeholders as to why this solution and not an alternative, hand-holding the design and development team and also to some extent the end users to have it implemented the same way it was intended.

With all the above, let us now try to identify the essential skills of an aspiring Solution Architect:

Domain skills: A thorough understanding of the business domain is required to first understand the problem better and second to know the potential future needs that may emerge along the same lines of the problem space. It is also important that the person has the ability to learn things fast, as in most cases, there won’t be lead time for him to gain appropriate business skills. That means, the Solution Architect should also be a Business Analyst.

Technical skills: A thorough understanding on the technology currently in use in the organization, the technology currently in use in similar industry domain and the emerging future technology trends. This knowledge is essential to ensure that the solution does not become obsolete soon and that the organization is in a position to be ahead of completion in terms of IT enabled capabilities. At the same time, applying a new technology early in its evolution has its own issues and it is always better to wait for the technology to evolve and mature as more and more organizations adopt the same. It is important for a Solution Architect to closely follow technology trends and gather enough knowledge to understand what could be the best fit for solving various business problems on hand. He should have enough understanding of the technology chosen, so that his team (mostly himself) comes up with a prototype to establish that the solution really solves the problem. However, as the solution goes further down the implementation lane, the Solution Architect should be able to demonstrate hands on skills, so that he could command expertise and be the go to person for resolution of issues.

Team skills: Though mostly the Solution Architect will be an individual performer, some organizations may have dedicated teams to assist the Architects. Even in case of Architects acting as individual performers, the solution is implemented by a project team. So, the Solution Architect needs to be a team player and should with his domain and technical expertise, lead the team by example.

Process / Project Management Skills: Needless to say that the Solution Architects have to have the Project Management skills too, as one may have to manage the pre-solution activities as a project. For the purpose, he has to be familiar with the processes as well.
That means, the Solution Architect should be an all rounder with moderate to expert level skills in all the areas.  On top of these skills, one has to understand that solutioning is not just a science, but also an art, which is mastered with years of experience over as many projects and years involving various technologies and domains.

There could be different views on this and comments or opinions are welcome.
