What is the difference between methodology deviations and methodology revisions?
A Methodology Deviation is a project-specific change to an existing VCS-approved methodology due to a change in the conditions, circumstances or nature of a project. A Methodology Revision, on the other hand, is a global change to an existing VCS-approved methodology due to general developments in knowledge regarding changes in the conditions, circumstances or nature of projects. Methodology Revisions are subjected to the VCS Double Approval Process, whereas Methodology Deviations can be validated as part of the project validation process and are not subject to the VCS Double Approval Process. Further information on Methodology Revisions and Methodology Deviations is available in the VCS 2007.1 document and the VCS Double Approval Process guidance document.
