Timeboxing is a project management technique that allocates a fixed, maximum unit of time to an activity. This duration, known as a timebox, is set before work begins and cannot be extended. In practice, work stops when the timebox expires, regardless of whether the task is fully completed. This approach helps teams focus on delivering value within constraints, preventing scope creep and promoting efficient decision making. For instance, a daily stand-up meeting might be timeboxed to 15 minutes to ensure it remains concise and productive. Unlike traditional deadlines that focus on completion, timeboxing prioritizes completing as much as possible within the allocated time. This concept is frequently encountered in Agile methodologies and appears on exams like the PMI-ACP, CAPM, and PMP.
