Planning Physics Encyclopedia
Supply planning has physics. Learn the laws.
Supply planning is governed by repeatable laws — inventory, flow, lead time, capacity, constraint, and commitment. This is the operator's reference to the concepts that make a plan that works.
The required action is the gap — and usable future supply is the term most plans get wrong.
Planning physics map
The plan is a connected system.
The concepts relate — supply becomes promiseable, promises become commitments, commitments become a governed record. Trace the connections.
