While tracking project benefits, the project manager finds that some key performance indicators (KPIs) are not yet defined. What should the project manager do?

The project manager is responsible for ensuring project benefits are realized. When KPIs are undefined, the project manager must proactively address this gap. Coordinating with the benefit owner is the correct approach because the benefit owner is the individual or group accountable for realizing the project's benefits and understands the value proposition. Together, they can define relevant KPIs and gather necessary data to track benefit realization effectively. Referring the issue to the benefit owner without offering coordination is less proactive. While business analysts can assist, the primary responsibility for benefit definition lies with the benefit owner, with the project manager facilitating. Asking the program manager is incorrect as this is an operational project-level issue, not necessarily a program-level one.
