Time boxing

Encyclopedia : T : TI : TIM : Time boxing

Time boxing is a time management technique common in software development projects to plan out a project, for example the creation of a new IT system, by splitting the project up in a number of separate time periods (normally two to six weeks long). Each part has its own deadline and its own budget. By incrementally finishing one part at a time, a project can be successfully delivered.

The important thing about Time Boxing is that the dates are not flexible, but the deliverables are. Without time boxing, when the deliverables cannot be delivered, the deadline slips. With time boxing, the deadline is fixed, and the deliverables are adjusted (hopefully in agreement with the customer/user). This goes hand-in-hand with MoSCoW prioritization of deliverables. Time Boxing is a core element of the rapid application development software development process and of DSDM.

Time boxing and agile change management techniques go hand-in-hand: With time boxing you regularly deliver working software, and with agile change management you ensure that you deliver the highest priority value as defined by the stakeholders.
