Don’t Automate Complexity

Implementing Lean Software Development (page 72)

We are not helping our customers if we simply automate a complex or messy process

Resumo

Foco no MVP, de olho no objetivo final

Ter em mente todos os princípios do Lean (e não só o que te convém)

Cuidado com IFs

Não automatize complexidade
