Production planning rarely fails because of a wrong tool.
It fails because planning is often treated as a promise,
not as a decision based on real constraints.
Planning starts from dates instead of resources
Many companies plan by starting from delivery dates.
But dates do not produce parts.
People, machines and available hours do.
When planning ignores real capacity, failure is only a matter of time.
Too much work is accepted without awareness
Having more work than capacity is not wrong.
Not knowing it is.
When overload is hidden, every delay becomes an emergency
and planning loses credibility.
Experience is ignored or replaced by theory
Planning often fails when:
- experience is not considered
- decisions are made far from the shop floor
- theory replaces reality
A plan that ignores experience will never survive execution.
Planning is confused with control
Planning is not about controlling people.
It is about making problems visible before they explode.
When planning is used only to check delays, it is already too late.
A realistic plan accepts constraints
A solid production plan:
- accepts limits
- shows consequences
- supports decisions
It does not promise what cannot be done.
