Teradyne Results Using PSP and TSP
The first organization to report their results after using both PSP and TSP was Teradyne. Their return on investment (ROI) analysis indicates that by using PSP and TSP on two projects totaling 112 KLOC, they saved $5.3 million in engineering time, or approximately 120 hours/KLOC in integration, system, and field testing. Quality levels improved 20 times over prior projects and actual effort and schedule were within 8% of plan (early). Teradyne estimates the cost of PSP training to be one month per engineer. Below are specific details about one of Teradyne's projects.
