A STUDY OF QUALITY IN THE PROCESS OF SOFTWARE PRODUCT DEVELOPMENT ACCORDING TO MAINTAINABILITY AND REUSABILITY

Our research indicates the modality by which algorithm modifications imply intervention in modules where expressions are evaluated or selections of elements are performed, the conclusion being the fact that in order to design robust software, a clear definition of the modules is necessary. Thus, the weak module which can be easily modified must be defined and placed so as not to affect other modules through modifications applied to them. The reusability issue is even more important as the main software producing companies have developed class libraries which reduce programming efforts. It is thus possible to start the realisation of software with personnel no larger than 15 people, but with high qualification and logistical resources. The problem of reusability occurs especially in the interference area. In designing interfaces, graphic elements are dominant, as well as those of information search-find. All this implies the definition of text placement and designing parts of the text which determine actions or operation selection. The problem of reusability occurs when in new software products conversions, compressions, sorting and optimisations as operations with extremely low proportion in the computing volume must be introduced, but which represent significant consume from the point of view of the programming effort.
