Read whether a productivity quote is per person or per whole crew.
Will multiplying an already crew-level rate overstate output?
Use the matching calculator
Use this decision sequence
- Identify whether the supplied output rate describes one person or the complete stated crew.
- Use the per-person rate basis only in the person-hours model.
- Retain productive hours separately from total attendance time.
- Check that changed crew size does not imply unchanged proportional productivity without supporting data.
Keep the quantities distinct
| Quantity or assumption | How to use it |
|---|---|
| Per-person productivity | Can be multiplied by the stated number of productive people under the model. |
| Crew productivity | Already covers that crew and must not be multiplied again. |
| Elapsed duration | Also depends on schedule and resources. |
Worked comparison
An illustrative whole-crew rate of 10 units per hour for four workers yields 80 units over eight productive hours. Treating that 10 as a per-person rate and multiplying by four again predicts 320. A per-person input equivalent to that measured crew rate would be 2.5 units per person-hour, under the same crew and workflow assumptions.
Check before using the estimate
Rates and productive time are supplied planning inputs, not guaranteed production or staffing recommendations.
All dimensions, product properties, prices and specifications in this example are illustrative arithmetic inputs. Use the values from your measured plan, selected product data sheet and supplier quote. This guide does not choose construction specifications or certify safety.
