Constraint Identifier

Constraint Identifier

Overview

The Constraint Identifier skill provides comprehensive capabilities for identifying and exploiting system constraints using Theory of Constraints (TOC) principles. It supports bottleneck identification, throughput analysis, and implementation of the five focusing steps.

Five Focusing Steps

Step 1: Identify the Constraint

• Analyze capacity vs. demand at each step
• Look for WIP accumulation points
• Identify resource with lowest throughput

Step 2: Exploit the Constraint

• Ensure constraint never starves or blocks
• Eliminate waste at constraint
• Maximize constraint utilization

Step 3: Subordinate Everything Else

• Pace non-constraints to constraint
• Implement pull system from constraint
• Don't overproduce at non-constraints

Step 4: Elevate the Constraint

• Add capacity at constraint
• Reduce setup time
• Improve quality at constraint

Step 5: Prevent Inertia

• Return to Step 1
• Find new constraint
• Continue improvement cycle
