An experience report on the personal software process

Individual developers can use quality analysis and management techniques that many consider applicable only to projects and organizations. One of the authors, a software practitioner, explains how the personal software process (PSP) gave him the training he needed. The software industry´s demand to achieve predictability and consistency in the face of rapid change is significant. The PSP framework helps an individual to meet these demands. Using the PSP has provided the author with several benefits. His estimation accuracy has improved significantly. However, adding more data to his historical database will help further improve his estimating skills. As it is said: “there is no substitute for hard work to be successful”.
