Where it usually breaks
And how to keep it from happening.
- A partial arrival is counted as a completed line. Check the remaining quantity and final accepted receipt.
- A lateness-only rejection is treated as a quality defect. Read the reject reason and quality-defect quantity separately.
- An excluded line has no documented basis. Check who approved the exclusion and why.
- A small or missing sample looks like a firm trend. Read coverage, line counts and no history in the next bid comparison.
