Why is the SEP a “living” document?
A good SEP provides a roadmap to the technical execution of a program. Program personnel should use the SEP as a reference to understand the overall technical approach to a program. A SEP should be continuously updated as plans are solidified or modified, activities move from plans to historical facts, known risks are mitigated or significantly changed, new risks are identified, new tools and technologies are adopted, and as a myriad of other factors cause an adjustment to the program’s overall technical approach.
