"We had plenty of Spare Parts but they were deployed in the wrong places. This meant that we were always running out of items somewhere in the logistic system, but in other parts we had spares that never moved. Some were even still sitting their in their original wrappers. We used Spares Calculator to workout exactly how many spares to keep at each level in the logistic system and our lives are now much easier."

If so, use Spares Calculator to provide you with the mathematical justification needed to support your business case.
"We needed 26 spare units. However, the sponsor would only authorize 12. We used Spares Calculator to prove exactly how risky the proposed level of spares was."
Is there a business case?
Spare parts can represent a major capital investment. In a typical maintenance intensive organization, spare parts could easily:
- Account for 2-5% of the net value of a company.
- Account for 5-20% of the cost of a new system.
- Sit on a shelf their whole life without ever being used.
In a sophisticated commercial or military system, a spare part might cost upwards of $2,000-$50,000.
A system outage can be even more expensive. An outage of a commercial airliner, broadcast system, telecommunications network or industrial process could cost upwards of $10,000-$100,000.
An outage of a military system could cost an immeasurable amount in terms of human lives.
Spares Calculator is a low cost product that could provide your organization with a massive return on investment.
System Operators: Save just one single high value spare part, or avoid one single major system outage and make a full return on your investment.
System Suppliers: Justify one single spare part or avoid one single support penalty payment and make a full return on your investment.
