Risk Management Plan

The plan recognizes a learning curve and includes a reduction in the “RPN” value for work accomplished without nonconformances. The plan can be applied to an individual part, individual customer or to support the business model of the organization. The plan is supported by a robust quality management system that exceeds specification requirements.

The plan pinpoints specific areas for mitigation efforts before the first chip is machined or the first component is assembled. Application of the Risk Management Plan reduces normal risks associated with complex, critical jobs, by detailing where the risks are and then building processes to abate those problem areas.
