Research On Applying Statistical Process Control Technique To Software Development Process

Statistical Process Control (SPC) has been acting as a gigantic drive in terms of bettering production process, efficiency and quality. Immeasurable value has been created for many enterprises since the successful implementation of SPC in manufacturing industry while establishing theoretical and practical fundament for its application in software industry. This paper introduces how we induct SPC technology into software development field as to realize transparency in project and quantitative management.Aiming at particularity of software development, the author mostly explains the principle of Single-variable SPC technology and usage of X-Rs chart and C chart integrating a few examples. Meanwhile, the author has studied the concept and principle of Multi-variable SPC (MSPC) and analyzed the process parameters which have existing correlations using Principle Component Analysis. Also, the application of multi-variable SPC in software development process has been achieved successfully utilizing the major causes found in the contribution charts. At the same time, based on the above studies, the author developed a handy charting tool for control charts based on MS Excel and showcased the material applications of the two process control methods in software development process.
