IT Strategic Plan | 20 Action Item 4:3 Legacy enterprise systems are based on outdated technology. As a result, the University should accelerate the upgrade and/or the replacement of such systems with new ones so they are made modern, functional, accessible, and more readily supported. Representatives from the UK community should be involved in the selection and specification of such systems to assess their functionality, accessibility, and usability. As legacy systems age, the necessary resources to support, maintain, and develop these systems become more costlyandscarce. Asaresult,actionsmustbetakentoensure the continued upkeep of legacy systems, while preparing for end of lifecycle and ultimate replacement. An investment lifecycle model should be applied to all enterprise systems to determine their position on the cost versus maturity curve overlaid with the risk tolerance attributed to the system. By taking a comprehensive approach to identifying systems in need of replacement and better planning for the lifecycle of existing and new systems, the University can develop a sound financial resources plan and distribution schedule, to better cope with the high cost of upkeep and replacement of such systems. Action Item 4:4 In collaboration with other University stakeholders, ITS should assess present standards where they exist and ascertain applicable architectures and tools so that college and department based systems may incorporate or scale up securely and efficaciously with the broader enterprise system landscape. Recognizing that there are systems that are tangential to main enterprise systems, and that such systems often perform critical services in local environments, a common development framework is needed. While college/ department-based systems may be viewed in the context of specific necessities, if they are developed outside of supportable architectures, their long-term efficacy is doubtful and can impact the entire University. Special needs and demands for local entities to develop specific requirements for their programs should be considered in accomplishing this action item so those needs are not adversely impacted.
