CPA · Question 02 · Area 1: Business Analysis

A manufacturing company is analyzing its production process to identify bottlenecks. The process involves three sequential stages: Machining, Assembly, and Finishing. <br/><br/>- Machining capacity: 10,000 units/month<br/>- Assembly capacity: 8,000 units/month<br/>- Finishing capacity: 12,000 units/month<br/>- Current Demand: 9,000 units/month<br/><br/>The company implements a process improvement in Machining that increases its capacity to 11,000 units/month at a cost of $50,000. What is the impact on the company's total throughput?

Answer options:

A.

Throughput remains unchanged at 8,000 units.

B.

Throughput increases to 9,000 units to meet demand.

C.

Throughput increases to 11,000 units.

D.

Throughput increases to 8,500 units (average of capacities).

How to approach this question

Identify the bottleneck (the stage with the lowest capacity relative to demand). Determine if the proposed change affects the bottleneck. If not, throughput does not change.

Full Answer

A.Throughput remains unchanged at 8,000 units.✓ Correct
A
The system's throughput is limited by the bottleneck resource. <br/>Capacities:<br/>- Machining: 10,000<br/>- Assembly: 8,000 (BOTTLENECK)<br/>- Finishing: 12,000<br/>Demand: 9,000<br/><br/>Current Throughput = 8,000 (limited by Assembly).<br/>Improving Machining to 11,000 does not address the Assembly constraint. Therefore, total output remains capped at 8,000 units.

Common mistakes

Assuming increasing capacity anywhere increases output; confusing demand with capacity constraints.
