MRP Data Analysis & System Implementation 2

Question 1

When analyzing MRP output, a planner notices that planned orders are being generated for items already in stock above safety stock levels. What is the most likely cause?

Accepted Answer

The safety stock level is set higher than the on-hand quantity

Answer

When safety stock exceeds on-hand inventory, MRP interprets the gap as a net requirement and generates planned orders to replenish up to the safety stock level.

Question 2

A company wants to evaluate the accuracy of its MRP system after implementation. Which metric directly measures how well the system predicted actual demand?

Accepted Answer

Mean absolute percentage error (MAPE) of demand forecasts

Answer

MAPE measures the average percentage deviation between forecasted and actual demand, directly assessing MRP forecast accuracy.

Question 3

During MRP system implementation, which data element must be verified for every purchased item to ensure accurate planned order release dates?

Accepted Answer

Vendor lead time

Answer

Vendor lead time offsets planned order releases backward from the need date so materials arrive in time; inaccurate lead times directly cause late or premature orders.

Question 4

An MRP analyst is reviewing pegging data. What does pegging allow the analyst to determine?

Accepted Answer

The source demand driving a specific planned order

Answer

Pegging traces a planned order upward through the BOM to identify which parent demand or sales order created the requirement.

Question 5

Which type of data cleansing activity is most critical before going live with an MRP system?

Accepted Answer

Reconciling on-hand inventory balances to physical counts

Answer

Inaccurate on-hand balances directly corrupt MRP net requirement calculations, so physical inventory reconciliation is essential before go-live.
