• Baseline schedule  -  A fixed project schedule.

### C

• Change request  -  Outlines a problem and proposes an action to address the problem.
• Commercial off-the-shelf  -  Commercially available items that do not require the procuring organization to perform modification to meet requirements.
• Concept of operation  -  A document describing how a system operates during the life cycle phase to meet stakeholder expectations.
• Constraint  -  A condition or occurance that might limit, restrict, or regulate the project.

### D
