Quick Definition:
The Theory of Constraints (TOC) is a management philosophy that focuses on identifying and managing the single most important limiting factor (the constraint or bottleneck) that stands in the way of achieving a goal.
The 5 Focusing Steps
- Identify the Constraint: Find the bottleneck in your project process.
- Exploit the Constraint: Ensure the constraint is used to its maximum capacity.
- Subordinate Everything Else: Align all other processes to support the constraint.
- Elevate the Constraint: Invest in more resources or better technology to increase the constraint’s capacity.
- Prevent Inertia: Once the constraint is broken, go back to step 1 and find the next one.
TOC in Project Management
In PM, the constraint is often a specific resource (e.g., a highly skilled developer) or a specific process (e.g., the testing phase). By focusing on these constraints, PMs can significantly improve project throughput.
