CASE STUDY NARRATIVE FOR No: BRIEF DESCRIPTION OF CASE STUDY: Case 4: We did not tell Program Management. We decided they would only be told if the other part achieved a solution and our part became the unique critical path. We did fund an internal program in the Manufacturing Technology organization to develop an alternate production technique for either in-house or out-sourced production. The supplier was informed of this action since there was some evidence that the low yield was being used to justify a very high cost. As the Manufacturing Tech engineers developed a breakthrough approach, the supplier also discovered a solution and the price dropped as yield increased. Although there were a few gray hairs generated, the production and spares requirements were always met, and we did not lose untold hours in special status reviews
