Project Management Professional (PMP) Practice Exam

You need a batch of 100 identical valves which will be custom made for your project to build a food processing plant. There is a risk of deterioration of victuals during processing; therefore you placed requirements on the quality of the raw materials for the valves, which will make production very costly. Unfortunately, in order to test the valves against these requirements, you would have to destroy them. And you have no experience with the vendors at all. What should you do?

1. Do 0% inspection. You have to trust the selected supplier that they will use the materials according to your specification.

2. Negotiate a contract over more than 100 items and perform acceptance sampling for the surplus of the batch on delivery.

3. Require the seller to supply the valves together with appropriate certificates from their raw materials suppliers.

4. Do 100% inspection on delivery to your premises, then order another batch of 100 valves.

The correct answer is: Negotiate a contract over more than 100 items and perform acceptance sampling for the surplus of the batch on delivery.

Performing acceptance sampling for the surplus of the batch on delivery is the best option in this scenario. Option A is not ideal as it involves trusting the supplier without any inspection. Option C is not enough as it only requires certificates from raw material suppliers, not the actual inspection of the valves. Option D is not efficient as it involves double the cost and effort of ordering another batch. Negotiating a contract over more than 100 items and performing acceptance sampling for the surplus of the batch on delivery is a cost-effective solution that ensures quality control without risking the destruction of the entire batch of valves.
