Operations Management Exam Guide
This Operations Management exam focuses on practical knowledge and real-world application scenarios related to the subject area. It evaluates your ability to understand core concepts, apply best practices, and make informed decisions in realistic situations rather than relying solely on memorization.
This page provides a structured exam guide, including exam focus areas, skills measured, preparation recommendations, and practice questions with explanations to support effective learning.
Exam Overview
The Operations Management exam typically emphasizes how concepts are used in professional environments, testing both theoretical understanding and practical problem-solving skills.
Skills Measured
- Understanding of core concepts and terminology
- Ability to apply knowledge to practical scenarios
- Analysis and evaluation of solution options
- Identification of best practices and common use cases
Preparation Tips
Successful candidates combine conceptual understanding with hands-on practice. Reviewing measured skills and working through scenario-based questions is strongly recommended.
Practice Questions for Operations Management Exam
The following practice questions are designed to reinforce key Operations Management exam concepts and reflect common scenario-based decision points tested in the certification.
Question#1
Which statement is true about capacity requirements planning (CRP)?
A. Production capacity is created for future production items.
B. Human capital adequacy is analyzed for given work centers and production items.
C. Each product item is individually addressed regardless of relevant holistic processes.
D. Available capacity is compared to calculated workloads of relevant items.
Explanation:
The correct statement about Capacity Requirements Planning (CRP) is that available capacity is compared to calculated workloads of relevant items.
CRP is a planning technique used after material requirements planning (MRP). While MRP determines what and when materials are needed, CRP verifies whether the organization has sufficient capacity―in terms of machines, labor, and work centers―to execute the planned production schedule.
CRP works by:
Translating planned orders into workload requirements
Assigning those workloads to specific work centers
Comparing required capacity with available capacity
Identifying overloads or underutilization
The incorrect options misrepresent CRP:
CRP does not create capacity; it evaluates feasibility
Human capital adequacy is part of workforce planning, not CRP’s primary role
CRP evaluates workloads in relation to the whole system, not isolated items
Operations Management emphasizes CRP as a feasibility check, ensuring that production plans are
realistic and executable before release to the shop floor.
Question#2
What is one advantage of a periodic review system?
A. All items are reviewed during the same time interval.
B. Items are handled individually.
C. Less inventory is needed to protect against stockouts.
D. Inventory balances are updated after every transaction.
Explanation:
A key advantage of a periodic review inventory system is that all items are reviewed at the same time interval.
In a periodic review system:
Inventory levels are checked at fixed intervals (e.g., weekly, monthly)
Orders are placed to raise inventory to a target level
Multiple items can be ordered together
This approach simplifies administration and reduces ordering costs, making it especially suitable for:
Retail environments
Low-value or slow-moving items
Situations where continuous monitoring is impractical
The other options describe continuous review systems:
Individual item handling
Real-time inventory updates
Lower safety stock requirements
Operations Management recognizes periodic review as a trade-off between control and simplicity. While it may require higher safety stock, it offers operational efficiency and cost savings in many contexts.
Question#5
A company is experiencing an unusual amount of deliveries that are either late or an incorrect quantity.
Which type of system is used to identify and manage this type of problem?
A. ERP (enterprise resource planning)
B. CRP (capacity requirements planning)
C. FMS (flexible manufacturing system)
D. MRP (material requirements planning)
Explanation:
Comprehensive and Detailed Explanation (≈280 words):
The correct system to identify and manage frequent issues such as late deliveries or incorrect quantities is MRP (Material Requirements Planning) (Answer D).
MRP is designed to translate demand into detailed plans for what materials are needed, in what quantities, and when―and then to time-phased plan purchase and production orders accordingly. The document states that MRP combines detailed demand forecasts and actual requests, translates higher-level forecasts into more detailed requirements, and tracks customer requests. It also emphasizes that the MPS (which sets specific dates) is used to plan material requirements.
When deliveries are late or wrong quantities are shipped, a frequent root cause is that materials were not available when needed, orders were not released correctly, or priorities were mismanaged.
MRP directly addresses these by:
Exploding bills of materials into components
Time-phasing planned orders
Coordinating purchasing and production schedules
Updating plans when demand or system status changes
ERP is broader (enterprise-wide integration), CRP focuses on comparing capacity vs workloads, and FMS is a production technology―not a planning system for material timing and quantities. Because the symptoms described are classic planning/coordination failures in materials and order timing, MRP is the best fit.
