CMRP - Certified Maintenance and Reliability Professional MRO Spares Management Questions and Answers

Question 1

A plant is experiencing frequent production delays due to stockouts of maintenance parts. To address this, management wants to track the effectiveness of the MRO storeroom in fulfilling maintenance requests on time. Which of the following KPIs is the MOST direct measure of this objective?

Accepted Answer

Service Level (Fill Rate)

Answer

Service Level, or Fill Rate, directly measures the percentage of time a requested item is available in the storeroom when it is needed. This KPI is the most direct indicator of the storeroom's ability to support maintenance activities and prevent downtime caused by part unavailability. While the other options are important financial metrics, they do not directly measure the immediate availability of parts to the maintenance team.

Question 2

A reliability engineer needs to classify MRO inventory to prioritize management efforts. The goal is to focus the most control on the items that represent the highest annual consumption value. Which inventory classification method should be used?

Accepted Answer

ABC Analysis

Answer

ABC Analysis is a method of classifying inventory based on consumption value (annual usage quantity multiplied by unit cost). It applies the Pareto principle, where 'A' items are the small number of high-value items that account for the majority of the total spend, 'B' items are of moderate value, and 'C' items are the large number of low-value items. This allows for focused management effort on the most significant items ('A' items).

Question 3

In managing MRO spares, what is the primary purpose of maintaining accurate Equipment Bills of Materials (BOMs) within a CMMS?

Accepted Answer

To provide a direct link between an asset and the specific spare parts required to maintain it, improving planning accuracy.

Answer

An accurate Equipment BOM is a hierarchical list of all the repairable and replaceable parts for a specific piece of equipment. Its primary purpose in a CMMS is to enable maintenance planners to quickly and accurately identify the correct parts needed for a work order, which streamlines the planning process, reduces errors, and ensures the correct parts are reserved or ordered.

Question 4

Which of the following describes the best strategy for managing a 'critical spare'—a part that has a very long lead time and whose absence would cause a catastrophic production shutdown, even though it may never have been used?

Accepted Answer

Hold the item in inventory, ensure it is stored under optimal preservation conditions, and regularly verify its existence and condition.

Answer

Critical spares are managed based on risk, not turnover. Because the consequence of a stockout is extreme and the lead time is long, the best strategy is to hold the part in inventory, even if it is expensive and rarely used. Proper storage and preservation are essential to ensure the spare is in perfect condition when needed, and periodic verification confirms it hasn't been misplaced or used without documentation.

Question 5

A storeroom manager wants to improve inventory record accuracy without shutting down operations for a full wall-to-wall physical inventory count. Which of the following methods should be implemented?

Accepted Answer

Cycle Counting

Answer

Cycle Counting is an inventory auditing procedure where a small subset of inventory is counted on a specified schedule. This continuous process allows for the correction of inventory record errors as they are found, gradually improving overall accuracy without the massive disruption of a full physical inventory. It is a best practice for maintaining high inventory record accuracy.
