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.

Measuring Value Added

With agile, you choose to develop the functionality that provides the most value for the customer, post-development. What functionality does the customer receive and how can it be measured?

Testing Process Assessment

One of the biggest problems in software development is the quality assurance of the delivered product. This depends directly on the testing process used. See how to improve testing processes with the use of market data.

No-Code Low-Code

“Low Code/No Code” is a new development paradigm. It shortens re-development times (and costs) when an organization decides to move software system/application from old, legacy architecture to a newer, more maintainable one.
