Data Item Description (DID): Systems Engineering Plan (SEP)

3.1 The Systems Engineering Plan (SEP) defines the plans and procedures of an enterprise for the management and conduct by that enterprise of a fully integrated technical program in conduct of the engineering element(s) of a project. The term “SEP” is generic, and may be replaced with any meaningful name.
3.2 Throughout this DID, the term “enterprise” may be interpreted to mean "customer", "acquirer", "supplier", "contractor", "subcontractor" or other organizational element, as applicable, responsible for performance of
the work which is the subject of the SEP.
3.3 The SEP, including or supplemented by subordinate plans, is used to provide the primary work planning and process direction and guidance to the technical team responsible for conduct of the work. The SEP may also
be used to provide visibility, to a customer, of a tenderer's or enterprise's engineering planning and intended processes.
3.4 The content of the SEP is intended to be responsive to contract requirements, if any, but is not, itself, intended to be invoked contractually.
3.5 The “system” referred to in the name and scope of the plan may be an end-use system, a production system, a support system or any other type of system.
