Symptom: People are chronically overworked; i.e., there is more work expected than time available.
If people are continually overworked, it means that demand exceeds supply. There are a variety of reasons why this might occur. People could repeatedly underestimate the time projects will take, and then find themselves using any discretionary time to catch up on overdue projects. Or people might be agreeing to projects even if they don't have the resources to do them.
Client decision processes may also be at fault. Particularly with internal staff organizations, clients may feel entitled to whatever they think they need, whether or not the organization has the resources to deliver it.
