5.5 Validate Scope
The Validate Scope process establishes and validates the acceptance of completed project deliverables. As deliverables meet established criteria and are accepted this process provide a checklist of progression toward project completion. It provides objective validation to the deliverable acceptance process increasing the prospect of project final product or deliverable's acceptance. Farther down the page is the knowledge area:
The Inputs, Tools and Techniques and Outputs are listed below in figure 38.

Process Definition
Completed deliverables which have been through the quality control process are then reviewed by the project team and customer, or project sponsor, to ensure they meet the desired criteria. Once this is done a formal acceptance of these deliverables is signed and documented. This continues for each deliverable until project completion.
Process Assessment
This process provides a means of monitoring and evaluating each deliverable as they are completed; and providing a gage of how the established schedule so proceeding. This process rarely, but may be done in conjunction with the quality control process if for some reason the deliverable doesn't meet the project sponsor or customer standards.
Artifacts
Input
One of the Inputs is a requirements document. This document give the validate scope process a target to aim at. The artifact I've included is the scope statement from PMGT501 which contains the requirements for a sustainable home build project. Page 5 has the technical requirements desired by the customer. See 5.5.1
Tools & Techniques
A tool to validate the scope is group decision making. I've used an analysis of group studies in other artifacts. I found this one which put to the question should the Project Manager make the a decision individually or with a group. Before you get group discussion techniques you should be sure that it is appropriate. That is why I feel this is a suitable artifact for this process. Either way a decision needs to be made. See 5.5.2
Output
This change request is part of the outputs from a decision. As I had very few competed change request forms and many change control plans I've included the Change control plan from PMGT501. I has a change request form and all the processes to consider in completing and approving one. See 5.5.3
