USE OF STRUCTURED DESIGN AND DEVELOPMENT IN THE VALIDATION OF APPLICATION SOFTWARE

The structured design and testing of application software is an import ant element of GMP compliance. Because application software is custom- developed, one cannot rely on 'market hardness' as an indicator of sof tware quality. Structured design provides a means for understanding co mplex problems and evaluating system requirements. Communication among users, designers and implementers is facilitated. Valuable and usable documentation is produced. There are many existing CASE tools which c an assist in the structured design approach. The many benefits of stru ctured programming toward the end of validation are discussed within t his paper.
