Defer Commitment
Defer Commitment is a concept that promotes making decisions as late as possible, in order to avoid premature commitments that may lead to rework or waste. In Lean Software Development, this idea translates to delaying decisions until more information is available and there is a clearer understanding of the requirements and constraints. This approach allows teams to consider multiple alternatives, adapt to changing circumstances, and minimize risks. By deferring commitment, teams can maintain flexibility, which ultimately results in reduced waste, increased efficiency, and improved product quality.
Guide on Defer Commitment in Lean Software Development
Defer Commitment is a fundamental principle in Lean Software Development. It is also commonly referred to as 'Last Responsible Moment' decision-making.
What is Defer Commitment?
Defer Commitment is a strategy devised to tackle uncertainty in projects by making decisions as late as possible. It's about preserving options, keeping important and irreversible decisions open until the cost of not making a decision becomes greater than the cost of making a decision.
Why is it important?
Deferring commitment can maximize the project's flexibility by allowing more information to be considered before making important decisions. It helps to reduce rework and waste, improve software quality, and prevent the delivery of products that do not adequately meet user needs.
How it works?
Deferring a commitment involves two steps: identifying the last responsible moment to make a decision, and keeping your options open until that moment. This approach increases the chances of making a more informed and effective decision.
