Batch Sample Workload at 23% prep and documentation allowance: a worked example
Push prep and documentation allowance up to 23% and the picture changes. This example computes every intermediate figure at that operating point. you need to plan QC lab hours and hold time for a run of batches before they can be released
The inputs for this scenario
- Batch samples to test: 30 samples (unchanged)
- Lab testing rate: 4 samples / hr (unchanged)
- Prep and documentation allowance: 23 % (raised for this scenario; the documented default is 20)
Working through the calculation
- Applying the documented formula (Base testing time = batch samples to test / lab testing rate) to the inputs above produces each figure below.
- At this operating point the engine returns 9.23 hr for required qc testing time, the number this scenario is built around.
- At this operating point the engine returns 7.5 hr for base testing time.
- At this operating point the engine returns 23 % for prep and documentation allowance.
- At this operating point the engine returns 4 pieces / min for lab testing rate.
How this compares with the baseline
- Against the tool's baseline example, where prep and documentation allowance sits at 20% and the headline result is 9 hr, this scenario comes in 2.5% above the baseline at 9.23 hr.
- It computes the total QC lab hours to test a queue of batch samples, adding a prep and documentation allowance on top of raw testing time. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
Results at a glance
- Required QC testing time: 9.23 hr (headline result)
- Base testing time: 7.5 hr
- Prep and documentation allowance: 23 %
- Lab testing rate: 4 pieces / min
