✦ Synopsis

Effective software maintenance is essential to achieving global software competitiveness. Organizations' increasing dependency on software and the shortage of software skills combine to require an increase in the span of responsibility within the software maintenance function.

The span of responsibility determines the cost of software ownership since it is the amount of software depended on by the enterprise divided by the number of people who maintain the software. Managers of software maintenance can improve the span of responsibility by • establishing and using organizational resources in five manners to sustain operational support for existing information systems, • applying resources to strengthen four views of software maintenance, from individual to national, • creating and applying action to eliminate the 26 main shortfalls in doing software maintenance, and • reducing the seven main risks to information system quality.

This paper provides a call for action to improve software maintenance in order to strengthen enterprise and national global competitiveness.

We suggest that empirical studies of maintenance are difficult to understand unless the context of the study is fully defined. We developed a preliminary ontology to identify a number of factors that influence maintenance. The purpose of the ontology is to identify factors that would affect the resu
