Hands-On Software Engineering with Golang

Defer commitment

As with all the models in the agile family, the lean model is devoid of any attempt to force project stakeholders into making all the required decisions at the beginning of the project. The reasoning behind this is quite simple: people are more likely to be convinced that change is needed when they have not already committed to a particular set of actions.

The lean model actively encourages stakeholders to defer all the important and potentially irreversible decisions until a later stage in the project's development.
