Utilization is the concept of comparing productive time to unproductive time. Utilization is generally expressed as a percentage and is calculated as the ratio between productive time and all productive and unproductive time. Utilization is often used in project management to determine where resources are being expended and can be helpful in finding project resources that are underutilized.
