Abstract : The study of software error types, techniques for locating them, and recommendations for improvement of reliability are discussed. Interim results from a study of errors encountered in three large software packages are presented. Data collection and analysis schemes are summarized for subject data sets; and plans for data collection on a fourth software project are outlined. Finally, a survey of present software reliability models and a summary of TRW work in this area are given. (Author)
