Calculation method
Calculation method
Request cycle spans (business minutes)
Business time from each request’s first stage start to last stage end.
Mean elapsed stage duration (business minutes)
Average business duration for each supplied stage name.
Stage(s) with largest mean elapsed duration
Retain ties at the largest observed stage mean.
Between-stage business-time gaps by request
Cycle span−sum sequential stage durations; overlapping stages within one request are rejected.
Summed elapsed stage minutes by owner label
Aggregate elapsed approval intervals by supplied owner; these may overlap across requests and are not measured active labour.
Symbols and units
- a
- Sequential approvals: request ID, stage name, owner label, start timestamp, end timestamp
- b
- Business windows: weekday,start,end
- c
- Holiday dates, comma-separated, or none
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- A supplied sequential-stage elapsed-time decomposition on a fixed-offset business clock. It does not approve purchases, verify owner authority or infer individual productivity from elapsed intervals.
