Software ageing measurement and classification using Goal Question Metric (GQM) approach

As indicated by earlier researches, software products behave in a manner that is almost similar to the process of human ageing. Just as human beings get old, it is believed that software too can age, and even though ageing is unavoidable, it is possible to understand the reasons for its occurrence so that steps can be taken to control its impact. Being a logical product, software does not age in the physical sense. However, in certain situations, the software loses its significance and quality to its surroundings. This occurrence can be compared to the process of ageing. The software ageing function can be expressed in terms of its significance, frequency of failure, technology, costs and so on. The software can be revived and the process of ageing postponed if these factors can be ascertained and distinguished. Inspired by earlier works concerning software certification and value, we have been guided to develop a software ageing model together with its associated links such as ageing factors and the rejuvenation index. In order to realise the creation of such a model, it is necessary to carry out further research with regard to measurement and classification, and to this end the Goal Question Metrics (GQM) approach has been selected.
