Batch Record Review Load with batch records to review of 50 records: a worked example
This worked example runs the batch record review load numbers for a tougher week than the baseline: batch records to review of 50 records instead of the typical 100 records. Estimate QA batch record review hours from batch count, review time per record, and available reviewer capacity.
The inputs for this scenario
- Batch records to review: 50 records (the input this scenario stresses; the baseline uses 100)
- Review hours per batch record: 1.2 hr / record (held at the documented default)
- Available reviewer hours: 8 hr (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Required workload = Batch records to review × Review hours per batch record.
- Total load works out to 60 hr at these inputs, and this is the headline figure for the scenario.
- Hourly equivalent works out to 7.5 hr / hr at these inputs.
- Input load works out to 50 hr at these inputs.
- Load factor works out to 1.2 x at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where batch records to review sits at 100 records and the headline result is 120 hr, this scenario comes in 50% below the baseline at 60 hr.
- Use it for QA staffing plans, release-timeline forecasts, or sizing the impact of a production ramp on the review queue. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
