Principle: Deliver On Time
The DSDM’s philosophy requires a certain approach to project variables where time, cost, and quality are fixed, and scope is dynamic. The fact that DSDM projects are required to have a fixed duration is also reflected in this principle: Deliver on time.
Delivering on time (having a fixed duration) is a strategic decision: It helps us focus on the most important things, and align ourselves with the business. In other words, this principle also supports the Focus on the Business Need Principle.
One of the beauties of DSDM is that it’s more or less self-similar (like a fractal); i.e., the whole project is made of some elements (iterations or timeboxes), which are in turn built of smaller pieces, where most of the rules apply to all of them. In this case, having a fixed duration applies to all levels in a DSDM project.
Having a fixed duration can be represented as timeboxing, and one can say that DSDM projects are timeboxed.
