 In this Part 3, he provides A Framework for Controlling 
Scope Control Means Maintaining Baselines as the Scope EvolvesThis Part 3 outlines a framework of principles and 
procedures for controlling the scope of a project. The control process is described 
in the context of a generalized model of the life cycle stages of a project. The 
stages are marked by the issuance of a series of progressively more detailed designs. 
Each stage is a further step in the evolution of the configuration of the deliverable 
end result. The progression is from a set of user or client requirements to a 
functioning product, system, or facility. The stages, in other words, trace the 
evolution of the project scope. The process for controlling the evolution of scope centers on two sets of mechanisms. 
The first set ensures that the configuration of the end product, at each stage 
of its evolution, does not deviate from the client's requirements. An agreed upon 
requirements statement and a series of design reviews and freezes are the key 
tools in this case.The second set of mechanisms provides for amending the configuration in a 
disciplined fashion. Inevitably, changes arise, either because the requirements 
change, or because the design does not work. Procedures are described for reviewing 
and approving changes, and for incorporating them in the baselines.
