In many organizations, the people with the deepest spare parts knowledge are easy to identify.
They know which catalogue descriptions cannot be trusted, which suppliers regularly miss their quoted lead times, which parts are interchangeable and why certain inventory is held despite little or no recorded usage.
That knowledge is enormously valuable.
It is also a significant organizational risk.
When one or two experienced people are relied upon to interpret information, challenge questionable decisions and explain the history behind the inventory, the capability does not truly belong to the organization. It belongs to those individuals.
The weakness becomes visible when they retire, move to another role, become unavailable or simply no longer have time to answer everyone’s questions.
Documentation is part of the solution, but it is not enough.
- A procedure may describe the required steps without helping someone interpret an unusual situation.
- A spreadsheet may contain the correct formula while hiding assumptions that only its creator understands.
- A policy may state what should happen without giving people enough practical guidance to apply it consistently.
Real capability requires shared understanding.
Experienced people should help establish practical policies, agreed definitions, repeatable decision processes, useful examples and clear escalation pathways. Their expertise then becomes a foundation on which others can build, rather than knowledge that disappears when they leave.
This capability must also extend across functions. Maintenance, engineering, procurement, stores, supply chain and finance each hold part of the information required to make a good spare parts decision.
Not everyone needs to become a spare parts specialist. But everyone who influences the outcome needs to understand their role and work from a common decision framework.
A useful test is to ask:
What would happen if your two most knowledgeable spare parts people left tomorrow?
Would the organization continue making consistent decisions—or be forced to reconstruct years of knowledge through trial and error?
The full article explores how organizations can reduce this dependence and turn individual expertise into lasting enterprise capability.
