Traceability Foundations
Context
Where in the workflow the capture happened, and what it should be matched against.
Context is the stage
Identity and quantity work the same way at every stage. What changes is which stage you are in and what the capture is checked against.
Receiving
Checked against the purchase order
- Identify
- Measure
- Match
Processing
Checked against the recipe or job
- Pick
- Transform
- Record
Dispatching
Checked against the sales order
- Pack
- Verify
- Load
Putting the three together
Identity plus Quantity plus Context is Truth. Drop any one of them and you are back to a number somebody typed.
