Which of the following activities would not be a part of leveraging a project?

Verifying root cause is an essential part of the problem-solving process but does not specifically align with the concept of leveraging a project. Leveraging a project refers to maximizing the benefits derived from project outcomes and utilizing those results to improve processes, share knowledge, and identify additional opportunities for improvement.

Communicating project savings helps stakeholders understand the financial benefits and effectiveness of the project, which can bolster support for future initiatives. Sharing ideas and best practices is crucial for fostering a culture of continuous improvement, allowing teams to learn from past projects and apply those lessons in new contexts. Identifying "spin-off" projects involves recognizing additional opportunities that arise from the original project, which is a key aspect of leveraging resources and results for greater impact.

In contrast, verifying root cause is focused on diagnosing specific issues within a problem rather than maximizing the value or impact of a project outcome, which is why it is not considered a part of leveraging.
