Subsets of Resource Busy Time

Resource Waiting Time and Non-Waiting Time (Avg Res Wait, Tot Res Wait)–The time that a resource spends waiting. This occurs when an activity processing a transaction acquires a resource with the Wait option, and the transaction must wait for some reason (for example, waiting for another resource, or the transaction incurs blocked or inactive time).

Tot Busy = Tot Res Wait + (Total resource non-waiting time)
Resource Standard Time and Resource Overtime (Avg OT, Tot OT)–The time that a resource spends in standard time or overtime. A resource is in overtime if an activity acquires a resource and requires that it finish processing the transaction even though the resource should go out of schedule (become inactive) prior to finishing.

Tot Busy = (Resource standard time) + Tot OT
