Improving Estimated Resources in System Development

C.

To improve the estimated resources required in system development, an IS auditor may recommend several techniques, including:

A. Business areas involvement: One of the ways to improve the estimated resources required in system development is to involve business areas in the development process. By engaging with business areas, the IS auditor can identify the requirements and develop a clear understanding of the scope and objectives of the project. The involvement of business areas also helps to ensure that the project team's focus is aligned with the overall business objectives.

B. Prototyping: Prototyping involves the development of an initial version of the system to be used for testing, evaluation, and feedback before the actual development process begins. By creating a prototype, the development team can get an idea of what the end product will look like, identify potential issues, and make adjustments before moving on to the full development process. This can help to reduce the time and cost of the development process and improve the estimated resources required.

C. Function point analysis: Function point analysis is a technique used to measure the size and complexity of a software application. It helps to identify the number of inputs, outputs, queries, files, and interfaces required for a system. By using this technique, an IS auditor can develop a more accurate estimate of the resources required for the development process.

D. CASE tools: CASE (Computer-Aided Software Engineering) tools are software tools that support software development activities, such as modeling, coding, testing, and documentation. The use of CASE tools can help to automate some of the development processes, which can reduce the time and cost of the development process. An IS auditor can recommend the use of CASE tools to improve the estimated resources required in system development.

In conclusion, all of the options A, B, C, and D can be recommended by an IS auditor to improve the estimated resources required in system development. However, the most appropriate option would depend on the specific needs and circumstances of the organization.
