Three of these projects used PSP-trained engineers and three used either engineers untrained in the PSP or a mix of trained and untrained engineers. Of the projects that used only PSP-trained engineers, all were delivered on or ahead of schedule, and only one defect was found in acceptance testing. None exhibited any defects during several months of customer use. Summary of AIS Project Data. Management reviews the costs and benefits of PSP introduction and publicly supports the introduction plan.
Training is done by project team, and the supervisor is trained with the team.
Management views the PSP course and exercises as part of the job and tracks progress with the same priority as a project. Following training, the PSP methods are immediately applied to a project. All directly involved line management are familiar with and support the PSP strategy and have been trained in how to manage PSP-trained engineers. Training has been most successful when the organization's management has already initiated a CMM process improvement effort. It also is important that an SEI-qualified PSP instructor be used.
