ISBSG Maintenance and Support Data

Lessons Learned from the ISBSG Maintenance & Support Dataset

Arlene MinkieWicz (Unison)

It is generally believed that the effort associated with software maintenance activities represents somewhere between 65 and 85 percent of an application’s total ownership cost.

Despite this fact, if one were to peruse recent research, it would quickly become obvious that there are very few studies focused on this topic.  Not to say there have been none: in recent years, the US Department of Defense has put considerable effort into studying this for their software systems, but beyond that very little seems to have be available.

This study focuses on the International Benchmark Standards Group’s Maintenance and Support (ISBSG M&S – Release 7 2020) dataset.   The focus of the study is to identify maintenance trends and likely effort drivers aligned to the various activities considered to be part of the overall maintenance activity. Results will be stratified to apply to specific industries, application types and programming languages as appropriate.
