Cost-Accounting Theory-of-Constraints Five Focusing Steps Identify Exploit Subordinate Elevate Repeat

? What this actually is

The Five Focusing Steps—Identify, Exploit, Subordinate, Elevate, Repeat—are a framework from the Theory of Constraints (TOC) used in cost accounting to maximize throughput and improve overall performance. This matters because it helps organizations identify and address bottlenecks, optimize resource allocation, and ultimately increase profitability. The core idea is to systematically focus on the most constrained part of a process to improve the entire system.

? The core logic (or formula)

1. Identify the Constraint: Determine the bottleneck or limiting factor in the process.
2. Exploit the Constraint: Maximize the throughput at the constraint without additional investment.
3. Subordinate Everything Else: Align all other processes to support the constraint.
4. Elevate the Constraint: If necessary, invest to increase the capacity of the constraint.
5. Repeat: Continuously identify and address new constraints as they arise.

? Hidden rule nobody explains

In practice, the constraint is often not where you think it is. It's crucial to use data and process mapping to accurately identify the true bottleneck. Many organizations waste resources by focusing on the wrong part of the process.

? Practical example / breakdown

Let's consider a manufacturing company with three processes: A, B, and C. Process B is identified as the constraint.

1. Identify the Constraint: Process B is the bottleneck.
2. Exploit the Constraint: Improve efficiency in Process B by reducing setup times and increasing machine uptime.
3. Subordinate Everything Else: Ensure Processes A and C are aligned to support Process B, such as adjusting production schedules.
4. Elevate the Constraint: If necessary, invest in additional machinery or labor for Process B.
5. Repeat: After improving Process B, re-evaluate to identify the new constraint.

? Your move today

Goal: Create a process map for a simple manufacturing process and identify the constraint.

Step-by-step: 1. Draw a simple flowchart of a manufacturing process with three steps.
2. Label each step and note the time it takes to complete each.
3. Identify the step with the longest time as the constraint.
4. Brainstorm ways to exploit and elevate this constraint.

What to save: A completed process map with identified constraint and improvement ideas.

Five Focusing Steps Cheat Sheet

Example: - Identify: Process B takes 20 minutes.
- Exploit: Reduce setup time to 15 minutes.
- Subordinate: Adjust Process A and C schedules.
- Elevate: Invest in additional machinery for Process B.
- Repeat: Re-evaluate and find new constraint.

⚠️ Common mistakes & recovery

• Common Error 1: Misidentifying the constraint.
• Recovery: Use data and process mapping to accurately identify the true bottleneck.
• Common Error 2: Overlooking the need to subordinate other processes.
• Recovery: Ensure all processes are aligned to support the constraint.
• Quick Check: Verify that the throughput at the constraint has improved.
• Exam Tip: Practice identifying constraints in various scenarios to build intuition.
