Quantitative criteria are measurable and objective indicators that can be used to assess the costs, benefits, risks, and value of IT projects1. By using quantitative criteria, an enterprise can compare and prioritize different IT project proposals, justify and secure the required funding and resources, monitor and control the project progress and performance, and evaluate the actual outcomes and impacts of the project after implementation1. Quantitative criteria can also help to demonstrate the alignment of IT projects with the enterprise's strategic objectives and goals, and to communicate the value proposition of IT projects to the stakeholders1.
The other options are not the primary reason for using quantitative criteria in developing business cases for IT projects, as they are either secondary or unrelated benefits. Benchmarking project success with similar enterprises may help to identify best practices and areas for improvement, but it is not the main purpose of using quantitative criteria. Learning lessons from errors made in past projects may help to avoid repeating mistakes and enhance project quality, but it is not the main purpose of using quantitative criteria. Applying other corporate standards to the development project may help to ensure consistency and compliance, but it is not the main purpose of using quantitative criteria.
