Evolutionary Design
Why?
In a dynamic world we cannot assume we can design up front, because the context is changing faster and faster. Then we need to start with a minimum design and adapt it while growing and improving as we go. Evolutionary Design can help us.
What?
Evolutionary Design is an approach to incrementally grow a system while observing growth patterns and focusing on normalizing, optimizing and maximizing the growth.

Quotes
- “Evolutionary Design is like helping your plants grow, knowing what measures to take so they will be fruitful”
- “When evolving the design of a system we observe growth patterns that simplify the resulting system”
- “TDD as if you Meant It doesn’t guarantee full test coverage, you need to have tools and use them to check your work”
- “Taking only one decision at a time is Taking Baby Steps for Evolutionary Design”
- “First normalize, then optimize and only then maximize growth.”
- “Evolve rather than change”
- “If you are rigid, your software system will be rigid”
