The Project Control System (PCS) is a project information repository.
The purpose of the PCS is twofold:

The PCS provides an official information source for schedule, cost, risk, contract data requirements list (CDRL) items, and milestone information to be used by the total integrated product/process team (IPT) including the project management office (PMO), contractor/subcontractor, and customer.

The PCS provides easily readable graphics charts that are connected to the actual data files. The PCS information was designed to be Internet/Intranet capable. Viewing it requires only a Internet Browser and Acrobat Reader software. The PCS is “read only”, therefore, there is no risk of data corruption by the viewer. The information viewed in the PCS is updated various ways.
PIMSOL : Providing the project management team with an information source that performs a proactive role in quickly identifying areas of concern and managing by exception.
