All of you who are separating your developers from your testers? You are doing half-actions. Separating the writers from the developers and testers? Half actions there, too. Even when you define architecture and implement across the architecture, instead of by feature, that’s a half-action. A half-action means you have technical debt and will have to get back to that area of the product.
Silos encourage half-actions (or third-actions or sixth-actions). Defining the architecture and implementing across it encourages half-actions. Create a cross-functional product development team. Have them finish one feature at a time. That’s a full action.
