This case study is a critical analysis of Personal Software Process (PSP) that is used by various software engineers to collect and analyze data about their work. There have been a range of published studies that make use of data collected by PSP in order to draw quantitative conclusions about its impact upon programmer behavior and product value. The PSP discussed in this paper uses individual method for collecting and analyzing personal data. The idea of this paper is to perform an estimation of the quality of data that is obtained using PSP method. This case study assumed that the problems with the data quality attained from PSP measures can change some of the measures formed by the PSP that are widely used to evaluate its efficiency and effectiveness. This paper is divided into various sections that proves and presents the paper with accurate and reliable data that is obtained from the case study. The study concludes on the reliability on the PSP method that consistently records primary data values. It also raises questions about the accuracy of PSP that is a manual method used to collect and analyze PSP data. This paper suggests the use of integrated tool support that can be used for high quality PSP data analysis. It also states the use of external measures when trying to estimate the impact of PSP upon product quality and programmer behavior.
