I have a manufacturing control plan where I want all (100%) of the lot size/reserved serial numbers to be included in the shop order analysis. I have a question about when the lot size changes. Please see example and questions below.
Control Plan Data Point - control plan only has 1 data point
- Data Type = Categorical
- Inspection Description = 100% Inspection
- Inspection Percentage/Quantity = 100
Shop Order Analysis
- Shop Order Lot Size = 4
- Shop Order Reserved Serial Numbers = 1, 2, 3, 4
- Shop Order Analysis Sample Size = 4
- Shop Order Analysis Serial Numbers = 1, 2, 3, 4
- Results were entered for all 4 serial numbers.
Shop Order Lot Size is Increased
- Shop Order Lot Size = 6
- Shop Order Reserved Serial Numbers = 1, 2, 3, 4, 5, 6
- Shop Order Analysis Sample Size = Remains as 4 and cannot be changed
- Shop Order Analysis Serial Numbers = 1, 2, 3, 4, 5, 6
- Results must be entered for all 6 serial numbers.
Questions
- Why doesn’t the sample size in the control plan change when the lot size changes?
- Is there a way to, in this scenario, to only have to enter analysis results for the serial numbers that don’t already have results? For example, the original 4 serial numbers have results so I only want to enter results for the 2 new ones and not all 6.
The goal is to enter results for all of the serial numbers one time in the analysis.
Thank you for any input that can be provided.
