With a limited budget of $17,000 remaining, the product owner should prioritize features that provide the most value to the customer. This means considering the business needs, customer feedback, and potential value of each feature rather than focusing solely on completing all planned features. Features like the Reporting Module, which have not started and have a high estimated cost, might need to be reconsidered or deferred based on priority. By assessing which features deliver the most value to stakeholders and aligning with the overall objectives, the product owner can make the most efficient use of the remaining budget.
