Improve Spare Parts Inventory Performance by Making Better Decisions
Excess spare parts inventory ties up capital. Insufficient inventory puts equipment availability at risk. Inconsistent decisions can create both problems at the same time.
Improving performance requires more than software, inventory calculations, or new stocking rules. It requires people who understand how to make sound spare parts decisions and apply them consistently.
SparePartsKnowHow.com helps individuals, teams, and organizations develop the knowledge, tools, and decision-making capability to improve spare parts inventory performance.

Why Spare Parts Require a Different Approach
Spare parts inventory is not the same as retail, wholesale, or production inventory.
Demand can be unpredictable. Lead times can be long. The consequences of not having a part when needed can far exceed its purchase cost.
These differences mean that conventional inventory techniques do not always produce appropriate spare parts decisions.
The challenge is not simply to hold less inventory. It is to make better decisions about what to stock, how much to hold, and how those decisions are managed over time.
That is the thinking behind the Spare Parts Decision Framework.
