The authors present an assessment method for legacy system evolution. This work is part of the RENAISSANCE project at Lancaster Uni.
They measure the system's technical quality, its business value and the organisational characteristics in which the system operates.
Their method is designed to be iterative and can be used at a number of levels of detail.
The method provides answers to questions such as: how critical is the system; what are the business' goals; what are evolution requirements; what are the
anticipated and required lives of the system; what is the technical state of the system; is the organisation amenable to change; and are appropriate resources
available to carry out the reengineering.
They use a combination of expert opinion, available code and documents and questionnaires to gather relevant information about systems, components, hardware,
supporting software and the organisation.
They suggest a scoring scheme of 1 to 4 for various attributes (low implies concern). They propose the use of Sneed's assessment matrix to help decide on the
eventual course of action.
