CSCP Internal Operations and Inventory Questions and Answers — Questions and Answers
Question 1: A company is implementing an inventory management strategy for its extensive portfolio of products. The goal is to apply the most rigorous inventory control and forecasting techniques to the items that have the highest impact on overall inventory value. Which of the following tools is most appropriate for this purpose?
- Economic Order Quantity (EOQ)
- ABC Analysis (Correct answer)
- Material Requirements Planning (MRP)
- Just-in-Time (JIT)
Correct answer: ABC Analysis
ABC analysis is an inventory categorization method that classifies items based on their annual consumption value. It follows the Pareto principle, where a small percentage of items (A items) account for a large percentage of the total value. By segmenting inventory this way, a company can focus its limited resources on managing the most critical 'A' items with tighter controls, while applying simpler, less costly controls to 'C' items.
Question 2: A manufacturing firm uses a pull system to manage the flow of components on its assembly line. When a downstream workstation consumes a bin of parts, it sends an empty bin and an associated card back to the upstream workstation to authorize the production of a new bin of parts. This signaling method is a core component of which system?
- Kanban (Correct answer)
- Master Production Scheduling (MPS)
- Six Sigma
- Theory of Constraints (TOC)
Correct answer: Kanban
This scenario describes a classic Kanban system. Kanban uses visual signals (like cards, bins, or electronic signals) to trigger action in a pull-based production environment. Its primary purpose is to control the flow of materials and limit work-in-process (WIP) inventory by ensuring that upstream processes only produce what is needed by downstream processes.
Question 3: In a period of consistently rising raw material costs, a company wants to manage its reported income for tax purposes. By using an inventory valuation method that expenses the most recently purchased, more expensive inventory first, the company can report a higher Cost of Goods Sold (COGS) and thus a lower gross profit. Which inventory valuation method achieves this?
- First-In, First-Out (FIFO)
- Specific Identification
- Last-In, First-Out (LIFO) (Correct answer)
- Weighted-Average Cost
Correct answer: Last-In, First-Out (LIFO)
During periods of rising prices (inflation), the Last-In, First-Out (LIFO) method matches the cost of the most recently acquired (and therefore most expensive) inventory against revenues. This results in a higher COGS, which leads to lower reported profits and a lower income tax liability compared to other methods like FIFO.
Question 4: A planner has just finalized the Master Production Schedule (MPS), which outlines the quantities of each end product to be completed in each time period. What is the immediate next step that uses the MPS as a primary input to determine the specific quantities and timing of all subassemblies, components, and raw materials required?
- Sales and Operations Planning (S&OP)
- Demand Forecasting
- Distribution Requirements Planning (DRP)
- Material Requirements Planning (MRP) (Correct answer)
Correct answer: Material Requirements Planning (MRP)
Material Requirements Planning (MRP) is the process that directly follows the creation of the Master Production Schedule (MPS). The MRP system takes the MPS (what needs to be produced), the Bill of Materials (BOM) (what it takes to produce it), and the Inventory Records File (IRF) (what is already on hand) to calculate the net requirements for all materials needed to execute the master schedule.
Question 5: A warehouse manager is choosing an inventory replenishment policy for a low-value, standard hardware item. The supplier visits on a predictable schedule every two weeks. The manager finds it most efficient to check the stock and place an order only during the supplier's visit. Which inventory system is being described?
- Continuous Review System
- Periodic Review System (Correct answer)
- Two-Bin System
- Vendor-Managed Inventory (VMI)
Correct answer: Periodic Review System
A Periodic Review System is an inventory control model where stock levels are reviewed at fixed time intervals (e.g., weekly, bi-weekly). An order is placed at the time of review to bring the inventory level up to a predetermined maximum level. This contrasts with a continuous review system, where an order is placed whenever the inventory level drops to a specific reorder point.
Question 6: Which of the following processes is a medium-range capacity planning tool used to validate whether a proposed Master Production Schedule (MPS) is feasible given the available capacity of critical resources like labor, machines, and key suppliers?
- Resource Planning
- Capacity Requirements Planning (CRP)
- Rough-Cut Capacity Planning (RCCP) (Correct answer)
- Input/Output Control
Correct answer: Rough-Cut Capacity Planning (RCCP)
Rough-Cut Capacity Planning (RCCP) is used to check the feasibility of the Master Production Schedule. It provides a quick and approximate check on the capacity of critical resources to ensure there are no major bottlenecks before the detailed Material Requirements Planning (MRP) process is run. CRP is a more detailed, short-range check that is performed after MRP.
