CMS Manufacturing Information Systems & ERP 1 — Questions and Answers
Question 1: What does MRP stand for in the context of manufacturing planning systems?
- Material Requirements Planning (Correct answer)
- Manufacturing Resource Program
- Material Resource Processing
- Manufacturing Requirements Protocol
Correct answer: Material Requirements Planning
MRP stands for Material Requirements Planning, a system that calculates material needs based on the Master Production Schedule and Bill of Materials.
Question 2: Which of the following is NOT a required input for an MRP system?
- Master Production Schedule (MPS)
- Bill of Materials (BOM)
- Inventory status records
- Customer satisfaction survey data (Correct answer)
Correct answer: Customer satisfaction survey data
MRP requires three core inputs — MPS, BOM, and inventory records — customer satisfaction surveys are not part of material requirements planning.
Question 3: What is a Bill of Materials (BOM) in a manufacturing information system?
- A list of approved suppliers and their pricing tiers
- A hierarchical listing of all components and subassemblies required to build a finished product (Correct answer)
- A document recording all production overhead costs
- A schedule of pending customer orders by priority
Correct answer: A hierarchical listing of all components and subassemblies required to build a finished product
A Bill of Materials is a structured, hierarchical listing of every raw material, component, and subassembly needed to manufacture a finished product.
Question 4: How did MRP II (Manufacturing Resource Planning) expand upon the original MRP I system?
- It restricted planning to raw material ordering only
- It replaced financial systems with production-only data
- By incorporating financial planning and capacity planning alongside material requirements (Correct answer)
- It eliminated the need for a Master Production Schedule
Correct answer: By incorporating financial planning and capacity planning alongside material requirements
MRP II extended MRP I by integrating financial planning, capacity planning, and other business resources beyond just material requirements calculation.
Question 5: What is the primary function of an Enterprise Resource Planning (ERP) system in manufacturing?
- To integrate all core business processes across the organization into a unified information system (Correct answer)
- To manage only shop floor machine control operations
- To handle external customer relationship management exclusively
- To process payroll and employee benefits administration
Correct answer: To integrate all core business processes across the organization into a unified information system
ERP integrates all core business processes — finance, HR, supply chain, manufacturing, and more — into a single unified information platform.
Question 6: In an MRP system, 'lead time' is defined as:
- The time a production manager spends reviewing daily output reports
- The elapsed time between a customer inquiry and a formal quote
- The time required to procure or manufacture a component before it is needed in production (Correct answer)
- The time between annual inventory counts
Correct answer: The time required to procure or manufacture a component before it is needed in production
Lead time in MRP is the procurement or manufacturing time needed for a component, used to offset planned order releases so materials arrive when required.
Question 7: In MRP, what does 'time-phased requirements' mean?
- Material needs are spread evenly across the entire year regardless of demand
- Requirements are calculated and scheduled by specific time periods aligned with when materials are actually needed (Correct answer)
- Orders are placed only at the end of each fiscal quarter
- Inventory is valued using a time-weighted average costing method
Correct answer: Requirements are calculated and scheduled by specific time periods aligned with when materials are actually needed
Time-phased MRP calculates and schedules material needs within specific time buckets, ensuring materials are ordered and received precisely when production requires them.
