Today, concern for quality has become an international movement. Eventhough most industrial organizations have now adopted modern qualityprinciples, the software community has continued to rely on testing as theprincipal quality management method. Different decades have different trends in software engineering. The Personal Software Process (PSP) is anevolutionary series of personal software engineering techniques that an engineer learns and practices. A software process is nothing without theindividual programmer. PSP a data driven process customized to teaching individuals about their programming styles, helping software engineers further develop their skills in developing quality software. Apart from discussing about PSP as a framework of techniques to help engineers and their organizations to improve their performance while simultaneously increasing product quality, in this paper, the Personal Software Process definition, principles, design, advantages and opportunities are explained focusing on the incorporation of PSP concepts in software development practice.
