Which of the following is the BEST way for an IT steering committee to determine the benefits of an IT investment?

Measuring ROI during implementation is premature, as the full benefits and costs are often not realized until after the system is fully operational and mature.

Measuring NPV during a stage gate review is a good financial metric for project evaluation, but it's a point-in-time assessment and doesn't capture the ongoing value creation throughout the asset's entire life.

Measuring planned versus actual spend primarily assesses cost adherence and project efficiency, not the broader benefits or value generated by the IT investment itself.

Measuring value creation throughout the economic life cycle involves continuous monitoring and evaluation of both tangible and intangible benefits from the initial investment through its operational lifespan, providing a comprehensive view of its overall contribution to the business.
