Which option should be taken into account when developing a business case for an IT system?

When developing a business case for an IT system, considering the option of continuing with the current system is essential because it helps to establish a baseline for evaluating all other alternatives. This option allows for assessing the performance, costs, and capabilities of the existing system against the proposed changes. It leads to a comprehensive understanding of the current state, identifying gaps, and clarifying the necessity for investment in a new system.

In evaluating whether to continue or change, it becomes possible to conduct a cost-benefit analysis, comparing the anticipated benefits of a new IT system against the ongoing costs or potential risks of the current system. This ensures that decisions are made with a clear understanding of past performance and future needs, ultimately contributing to a well-rounded business case that addresses potential improvements effectively.

By taking into account the continuation of the existing system, stakeholders can make informed decisions about whether the time, effort, and resources required for a new IT system are justified compared to maintaining or upgrading what is currently in place.
