Allocation Work Assignment View

The work assignment view consists of a single view packet that assigns each available work unit to one or more ECS subsystems.

10.1.5 Architecture Background

  • Procuring COTS. Those subsystems whose implementation is planned to be satisfied largely by purchasing commercial off-the-shelf software have been assigned to a single con tractor in the hopes of achieving cost savings by localizing the tasks of product qualification, managing product evolution, and making sure that procured components are version compatible with one another. COTS is expected to dominate the Communications and System Management Segment (CSMS), and so it will fall to the infrastructure team to manage the acquisition and integration of those commercial products.
