Maintenance at ABB. II. Change execution processes (the state of practice)

For pt.I see Internat. Conf. Software Maintenance (1999). In large software organisations, a software maintenance process is seldom monolithic. Instead, it is a complex family of various processes collaborating with each other, where each process executes a clearly defined task. We describe and compare two change execution processes utilised within maintenance by two ABB organisations, namely ABB Automation Products AB and ABB Robotics AB. Thus, the paper is the report of the current state of practice in change execution at ABB. It also compares the collaborating maintenance processes used for the administration of software problems
