Managing Inventory of Returned Product: A Data Driven Approach

This experience paper describes some observations regarding trouble call rates and the number of repairs and the number of No Trouble Found (NTF) returns. Analysis of field data shows that there is a relationship between NTF returns and trouble call rate for a constant number of repairs. Trouble cal...

description	This experience paper describes some observations regarding trouble call rates and the number of repairs and the number of No Trouble Found (NTF) returns. Analysis of field data shows that there is a relationship between NTF returns and trouble call rate for a constant number of repairs. Trouble call rate is one important metric since it measures an activity that generates operational expense. A cost model is proposed, and ways to develop decision rules to guide the decision to keep devices in the service inventory based on return and repair history.
