Description
Summary:Little is known about the industrial practice of modernising legacy systems. To be able to study it, we have created RaMoLeS - an end-to-end process model for modernising legacy systems. It consists of four sub-models: (1) Assessment, (2) Retirement, (3) Reengineering, and (4) Renovation. It provides guidelines for making decisions on how to approach ageing systems. In addition, it designates activities for each of its sub-models. In this paper, we evaluate the state of modernising practice in four major Swedish organisations using RaMoLeS. Our results show that most of the organisations studied do not have any defined end-to-end modernisation process model to follow. However, they conduct most of the activities as designated in the RaMoLeS framework.
