Architecture is about context, right? So all these seemingly random decisions probably at that time is not so random. Every design choice that you make has alternatives. And you can only make the right trade-offs between these alternatives. If you look at, for example, design principles such as information hiding, that's a very good design principle. It becomes architecture if you do not just look at generic good design principles but you actually look at the business context in which you apply them.
“Architecture is context. You can only make the right trade-offs between alternatives if you know the context drivers."
Eltjo Poort is the architecture practice lead at CGI Netherlands with over 30 years of experience in the software industry. In this episode, Eltjo started by explaining the importance of architecture context and business drivers that can help an architect understand the different trade-offs and options in order to make the right architecture decisions. Eltjo shared the architect’s main responsibilities and how architects should avoid writing big and long architecture documents by understanding the different goals of an architecture document. Eltjo also shared his great insights on how we should deal with technical debt, “move slow and fix things”, and put a more balanced effort towards working on enablers in order to maintain sustainable pace in delivering great software. Towards the end, Eltjo shared a few anti-patterns that architects should avoid based on his article “Waterfall Wasteland and Agile Outback”.
