GP 2.9 Objectively Evaluate Adherence
People not directly responsible for managing or performing the activities
of the process typically evaluate adherence. In many cases, adherence
is evaluated by people within the organization, but external to the
process or project, or by people external to the organization. As a
result, credible assurance of adherence can be provided even during
times when the process is under stress (e.g., when the effort is behind
schedule or over budget).
