Abstract

The paper presents an overview of the process of understanding existing information systems in order to aid system evolution and maintenance. The outcome of the paper is largely based on the experiences gather from a system maintenance project. The paper argues that the process of understanding existing systems involves four major design abstraction levels. To achieve the highest level of design abstraction in the hierarchy, maintainer programmers have to follow a defined process to gain a complete understanding of the system structure and semantics.
