Design and Prototype

In Step 2, the predominate IPMC process groups are Executing and Controlling. (See Appendix B for a detailed discussion of the Executing and Controlling process groups.) At the completion of Step 1 and as a result of the Milestone I briefing, approval is received to proceed forward with Step 2 tasks to design and prototype the system. As an outcome of this approval, planning artifacts are established as baselines and provided to the project team to guide the work effort.

During Step 2 the project manager begins executing the approved project management plan and manages work efforts to design the system. These design activities will result in a validation of the approved and published baseline, as each component is detailed and vetted with the appropriate stakeholders. Typically, there are numerous requests for change during this phase, and the project team utilizes the change control procedures in the scope management plan to assess, decision and implementation change proposals. The project manager is required to report the impact of scope changes in the project Milestone II briefing.

The system design may take the form of a prototype system, proof of concept, a demonstration or, depending on complexity, the first production article. Step 2 tasks lead to the Milestone II briefing where the results of the initial design effort are reported and the decision is made to continue the project into system development.

If the prototype development funding is approved, the system development effort is authorized and begins. During System Definition a prototype is tested and further refinements are made to the various plans and documents based on information learned from the prototype.

Once system development is approved, it will be funded and the systems life‑cycle development and testing can begin.
