Software testing is one of the most critical tasks performed by a large data processing organization. Testing is important in the development of new systems, but it may have an even greater impact on the maintenance of the production systems. In spite of this, testing is rarely approached in the same disciplined manner as are other software production activities. Perhaps as a result of this situation, an organization can often achieve significant improvements in both software testing effectiveness and efficiency through a relatively low-cost investment in testing methodologies, tools, and techniques. This paper describes just such an investment undertaken by the Information Services Group of Chemical Bank. Particular emphasis is placed on how this program for testing improvement was implemented, in addition to what it consists of. Finally, results of the program to date are presented and analyzed.
