Question 1c. Assume you are the portfolio manager within the IT Systems Development section at UU, with a responsibility for managing the application portfolio. Some of the inhouse developed systems are legacy systems, mostly written in procedural languages and siloed data structures, with the result that these systems are becoming increasingly difficult to maintain and integrate with the rest of the UU environment. Describe three key criteria that would be important in deciding on the future of these systems. Justify why you think these criteria are important in deciding the fate of the legacy systems.
