WORK DISTRIBUTION IN INFORMATION SYSTEMS DEVELOPMENT, MAINTENANCE AND EVOLUTION
The kind of information systems in use today is at first sight very different from those that were devel- oped 20 years ago. On the other hand, it seems that we are still struggling with many of the same prob- lems as before, including late or abandoned projects and unfilled customer demands. In this article we present selected data from survey investigations performed by us in 1993, 1998, 2003, 2008 and 2013 among Norwegian organizations on how they conduct information systems development and mainte- nance. In particular we compare the data from 2008 and 2013. A major finding is that even if we witness large changes in the underlying implementation technology and methods used, a number of aspects such as overall percentage of time uses for maintaining and evolving systems in production compared to time used for development and the distribution of time on different maintenance activities is remarkably sta- ble, although some trends can be witnessed. On the other hand, because of the more complex infrastruc- tures supporting the application portfolio, and the increasing number of in particular external users an increasing amount of resources is used for other tasks such as operations and user-support than in the first investigations, although also this seems to have stabilised.
