The development phase is the process of authoring and producing the materials needed to meet the objectives.

The development phase builds on the Process Performance Objectives and measurement tools constructed in the design phase. The product of this phase is a detailed plan of action that lists step-by-step procedures for implementing the change. The plan also needs to include who is responsible for which elements of the project, and time schedules and deadlines.

During the development phase, all audio, video, and text materials are collected, prepared, or created. Documentation is prepared and the product is ready to be tested.
