An amplification is a note or example that is relevant to a particular discipline. The disciplines covered in this model are hardware engineering, systems engineering, and software engineering.

Each amplification is labeled with a heading that indicates the discipline to which it applies. For example, an amplification for software engineering is labeled “For Software Engineering.” An amplification is an informative model component.

An example of an amplification is the one that accompanies the specific practice “Establish and maintain the overall project plan content” in the Project Planning process area. The amplification states “For Hardware Engineering: For hardware, the planning document is often referred to as a hardware development plan. Development activities in preparation for production may be included in the hardware development plan or defined in a separate production plan.”
