One of the core values of agile is to deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale. This means that the project manager should seek ways to show the customer the value of the software as early and often as possible, rather than waiting for the final deliverables or a major milestone. By evaluating various delivery options, such as demos, prototypes, beta versions, or minimum viable products (MVPs), the project manager can get feedback from the customer and validate their needs and expectations. This will also help the project manager to prioritize the features that deliver the most value to the customer and align the team's efforts accordingly.
