I've found that there comes a point at which an employee becomes so saturated with work that spending additional effort to meet deliverables actually yields poorer quality results across the board. This is often less desirable than simply leaving work undone.
- Is there a formal term to describe this in the context of business management?
- Are there any well known studies that describe or otherwise characterize this?
An example I can use from a previous profession is operating an airplane "on the back side of the power curve." It's a condition in which a pilot must actually add more power to remain aloft. Maybe the power required is more than what is available.
