I Believe In Simplicity

Because Simplicity = Understanding

And Simple Explanations Are Passed On

But Simplicity Takes Effort

Incremental design means: designing the solutionwhile working at the problem,one usage example at a time.

What is Incremental Design?

Split problem into smaller problemsDefine usage examplesImplement the usage examples one by oneImprove your solution

Incremental Design Process

Split problem = Find incrementDefine usage examples = Identify BehaviorsImplementImprove your solution = Refactor

Incremental Design Process

Refactor: Minimize similarities

Identify ExamplesOrder them to add one notionSimplifyImplementRefactor

Let's discuss an example

TDD/BDD and Incremental Design

I'm writing a book (work in progress)

Your Questions?

The important thing is not to stop questioning

I'm guilty for this talk!
