Preventing Unused Applications

C.

The best way to prevent unused applications from accumulating in an organization's IT portfolio would be to implement asset life cycle management (option C).

Asset life cycle management involves managing assets from the planning and acquisition stage to the disposal stage. This includes the processes of acquisition, deployment, maintenance, and retirement or disposal of IT assets.

By implementing asset life cycle management, an organization can ensure that its IT portfolio is regularly reviewed and maintained, with unused or outdated applications removed in a timely manner. This can prevent the accumulation of unused applications over time, which can result in unnecessary expenses and security risks.

In contrast, the other options provided do not directly address the issue of unused applications.

A formal request for proposal (RFP) process (option A) is a method of soliciting bids from vendors for goods or services. While this may help an organization acquire new applications, it does not address the issue of managing existing applications in the IT portfolio.

An information asset acquisition policy (option B) is a policy that outlines the process for acquiring new IT assets. While this may help an organization manage the acquisition of new applications, it does not address the issue of managing existing applications in the IT portfolio.

Business case development procedures (option D) involve developing a justification for investing in a particular initiative. While this may help an organization justify the acquisition of new applications, it does not address the issue of managing existing applications in the IT portfolio.

Therefore, the BEST way to prevent the accumulation of unused applications is to implement asset life cycle management.
