Experiences on analysis of requirements quality

The quality of any product depends on the quality of the basis of making it, i.e., the quality of the requirements has strong effect on the quality of the end products. In practice, however, the quality of requirement specifications is poor, in fact a primary reason why so many projects continue to fail. Thus, the current approaches as applied in practice are clearly not enough to develop high quality requirements specifications. Also, the poor quality of the requirements is typically not recognized during requirements development. In this paper we present a method called LSPCM developed for certifying software product quality. We also describe experiences from using the method for analyzing requirements quality in three cases. The three different cases show that the checks in the LSPCM are useful for finding inconsistencies in requirements specifications, regardless of the application domain.
