Assume you are the portfolio manager within the IT Systems Development section at UU, with a responsibility for managing the applications portfolio. Some of the inhouse developed systems are legacy systems, mostly written in procedural languages, have siloed data structures, and are becoming increasingly difficult to maintain and integrate with the rest of the UU environment. 1. Describe three key criteria that would be important in deciding on the future of these systems and justify why you think these criteria are important. [Do not include the issue that 'legacy systems are difficult to maintain' in your list of criteria as this issue is already well known].
