Problem Solver


ZF has the ability to process complaints with suppliers in a quick and transparent way through use of an electronic interface. The ZF Group solution for this activity is the SupplyOn Problem Solver module (sometimes referred to as e-8D). Problems and errors can be analyzed together using the 8D method, and solutions found to avoid repeat errors.

The 8D method is a standardized problem solution process that consists of eight steps (8D = 8 disciplines). Following the eight steps helps to identify the real root cause of the problem and to resolve it permanently. It supports methods such as 5-Why, Ishikawa and Drill-deep-and-wide.


Use of the SupplyOn Problem Solver provides both ZF and suppliers with a number of benefits...

  • Transparency to issues and action items
  • Structured and clear data that can be analyzed
  • Standardization across ZF divisions, regions, locations
