The project manager should conduct a customer demonstration at the end of each build cycle to help the client understand the value delivered during project execution. This is a common practice in agile projects, where the team showcases the working product increment to the customer and solicits feedback. This way, the customer can see the tangible results of each iteration, validate the alignment with their expectations, and provide input for future improvements. This option aligns with the PMI-PBA practice guide, which states that
"demonstrations are a key technique for validating requirements and obtaining feedback from stakeholders" (p. 67). The other options are not the best choices because they do not effectively communicate the value of the product to the customer. Including a planned value (PV) calculation in the sprint report for each build cycle (option A) may provide a quantitative measure of the project performance, but it does not show the actual functionality or quality of the product. Providing the customer with the refined specification during each build cycle (option C) may reflect the changes or clarifications made to the technical requirements, but it does not demonstrate the working product or its benefits. Showing the customer a sprint burndown chart for each build cycle (option D) may indicate the progress and velocity of the team, but it does not reveal the features or value of the product.
