0 out of 100
Mark each answer honestly against the panel's grid: the total is calculated automatically.
Common mistakes that cost marks
- Accepting the supplier's invoice for the whole purchase order.
- Calculating the penalty on the value accepted only, whereas the contract bases it on the total amount of the purchase order, or forgetting to deduct it.
- Accepting the incomplete kitchen sets with a discount without an amendment or the programme's opinion.
- Forgetting the items in quarantine when calculating the space required.
- Failing to see that signing the delivery note before the count weakens the claim.
