Enclosure (1) to COMDTINST 5200.16
Category C Process
ECPs are evaluated by determining if any changes to the standard baseline are required, total SLC,
and the impact to the responsible support organization(s). SLC is the sum of all development,
procurement, deployment, maintenance/support, system manager support, network, end-user
support, and training costs for the installed life of the system. If no de-installation date is specified
in the project plan or ECP, a minimum period of five operational years will be used to calculate the
SLC. All funds regardless of type or origin that are used for any aspect of a system must be
included in the SLC calculation. SWIII CCB approval is required for ECPs with a calculated
system lifecycle cost greater than ,000. Enclosure (3) is the approved worksheet for calculating
SLC.
