Enterprise organizations require flexible software systems that can handle emerging market needs from time to time, chiefly to ensure the organization has a competitive edge in the market. On the other hand, several organizations still possess legacy software systems, which have definite functionalities but may limit their development progress to comply with emerging e-business needs. Off-theshelf systems might be one possible option if a decision for replacement is made. Equally, improving the architecture of a legacy system can be a valid option to consider as well. The decision on which approach to follow when dealing with a legacy software system must be made based on a thorough investigation of the nature of the system. This paper develops a conceptual framework to analyse legacy software systems in order to support CEOs in making informed decisions about the appropriate approaches to follow in order to keep their organizations functional and competitive.
