As a Product Owner, you are accountable for maximizing the value of the product and the work of the Scrum Team. To do this, you need to have a clear understanding of the product vision, the product value, and the product backlog management. Measuring feature usage is one way to gather empirical evidence of the value delivered by the product and the feedback from the customers and users. This data can help you validate or invalidate your assumptions, prioritize the product backlog items, and inspect and adapt the product strategy.
Therefore, measuring feature usage is not a waste of time, but a valuable practice for agile product management.
Moreover, as a Product Owner, you are also responsible for engaging with the stakeholders and customers, and providing them with transparency and openness. This means that you should share the data and the insights you gain from it with them, and invite them to collaborate with you and the Scrum Team. This can help you build trust and alignment, and foster a culture of experimentation and learning. Therefore, you should not hide the data or stop measuring it, but rather use it as a basis for constructive dialogue and decision making.
