Which of the following is a key activity involved in project closure?

Requesting that the customer complete a Customer Satisfaction (CSAT) survey is a key activity involved in project closure because it provides valuable feedback on the customer's experience and the overall success of the project. This survey helps to assess what worked well and what can be improved upon in future projects. Collecting this feedback is crucial for understanding client satisfaction, measuring project outcomes, and reinforcing relationships with clients. It also contributes to the continuous improvement process within the organization, ensuring that lessons learned are documented and applied to subsequent projects.

Merging project files, while important for documentation, is more of an administrative task rather than a direct activity aimed at gauging the project's success or client satisfaction. Initiating stakeholder interviews is typically associated with gathering insights during the project lifecycle rather than during the closure phase. Conducting project training focuses on transferring knowledge or skills associated with the project outputs, which does not directly pertain to assessing project completion from a customer satisfaction standpoint.
