Which artifact is used to capture knowledge gained during the project to improve future work?

• A. Stakeholder Register
• B. Project Charter
• C. Lessons Learned Register
• D. Risk Register

Answer: (C)

Capturing what you’ve learned from a project to improve future work is all about turning experience into actionable knowledge. The Lessons Learned Register serves as the formal repository for documenting insights from the project — what went well, what didn’t, why things happened a certain way, and recommended actions to apply or avoid in the future. It’s updated throughout the project and especially at phase ends or project close, and it becomes part of the organization’s knowledge base to guide future planning, decision‑making, and process improvements.

The other artifacts serve different purposes: the Stakeholder Register lists people and groups involved and their details; the Project Charter defines the project’s purpose, objectives, and authority; the Risk Register records identified risks and responses. While these are important, they’re not meant to capture the broad lessons learned intended to inform future projects, which is why the Lessons Learned Register is the best fit.
