MRP Material Requirements Planning Fundamentals 5

Question 1

A buyer notices that MRP has generated planned orders for a purchased item even though sufficient on-hand stock exists. The most likely cause is:

Accepted Answer

Inaccurate inventory records overstating on-hand quantities

Answer

If inventory records are inaccurate and overstate on-hand stock, the physical stock may actually be lower, causing unplanned shortages that MRP did not anticipate.

Question 2

Which metric directly measures the accuracy of inventory records critical to MRP performance?

Accepted Answer

Inventory Record Accuracy (IRA)

Answer

Inventory Record Accuracy (IRA) measures what percentage of item records match the physical count, and high IRA (typically ≥95%) is essential for valid MRP output.

Question 3

What is the purpose of 'time buckets' in a traditional MRP planning grid?

Accepted Answer

To define the time periods (days, weeks) across which requirements and receipts are planned

Answer

Time buckets are the discrete planning periods (commonly weeks) displayed across an MRP planning record, showing requirements, receipts, and on-hand balances over the horizon.

Question 4

When the same component appears at multiple levels of a BOM, the correct approach in MRP is to:

Accepted Answer

Consolidate all demand at its lowest-level code before planning

Answer

Low-level coding consolidates all demand for a common part at its lowest BOM level so MRP nets and plans it once rather than creating duplicate orders.

Question 5

Which scenario best illustrates the concept of 'offsetting' in MRP?

Accepted Answer

Scheduling a planned order release earlier than the need date by the item's lead time

Answer

Offsetting means the system backs off the planned order release date from the requirement date by the item's lead time to ensure timely arrival.
