Improving the quality of three products through improved testing: A case study

The keys to efficient testing are to detect problems as early as possible in the testing phase and to try and detect problems before they reach the customer. Three product offerings of a major software company are examined, and recommendations on how the testing and maintenance processes for these products can be improved are given. The rationale behind these recommendations is based on an analysis of the types of errors being reported in each product, when these errors are found, and in which modules they are found.<>
