In any network of dependent tasks, the longest chain of sequential dependencies determines minimum completion time.
Why This Is an Axiom
This is the critical path principle from CPM—a mathematical/theoretical truth about network dependencies. It is not empirical (not about how humans behave) but theoretical (about how dependency networks logically function). The curriculum adopts this as a framework for analyzing workflows.
Source Lessons
Sequential versus parallel steps
Some steps must happen in order while others can happen simultaneously.
Bottleneck mastery is systems thinking in action
Finding and resolving constraints is the practical application of systems thinking to your life.
Exploit the bottleneck first
Before adding capacity make sure the bottleneck is fully utilized.
Human bottlenecks in team systems
In collaborative work specific people are often the constraint.
Operational debt
Deferred maintenance on your systems accumulates and eventually causes failures.
The theory of constraints applied to personal systems
Identify exploit and elevate your personal bottlenecks systematically.
The operational weekly rhythm
A weekly cadence of planning review and adjustment keeps operations on track.
