(stakeholders: resource manager; capacity planner): Utilisation
is the percentage of the operational time that a resource is busy. On the one hand,
the utilisation is a measure of the effectiveness with which a resource is used. On
the other hand, a high utilisation can be an indication of the fact that the resource
is a potential bottleneck, and that increasing that resource’s capacity (or adding
an extra resource) can lead to a relatively high performance improvement.
