Yes, it will be very useful a software design that can evolve (develop, progress, make progress, advance, move forward, make headway, mature, grow, open out, unfold, unroll, expand, enlarge, spread, extend). I do not want to rewrite a lot of code from the scratch from time to time.
The main question is if it is sufficient ?
In fact, I will want a software that could follow the business.
That mean this software could be changed with the business needs changes. These changes could be small or complex, could be rare or often. Or <even late>.
That mean this software could be changed with reasonable cost, without unnecessary waste.
That mean this software could be changed indefinitely change easy and economically. The software will not have too much technical debt and the team will be always be prepared and <in shape>.
That mean my software & my process should be Adaptive and Lean.
Agile.
Agile Design = Adaptive-Lean Design
