I would establish a framework to answer these questions Step 1:Clarify - What are user saying? Is there any data to tell us something is wrong? Step 2: no input / data given the assume your own use case / problem to solve - E.g Birthday notifications getting lost in the slew of notifications Step 3: Identify goal of the improvement. e.g perhaps more user saying happy birthday Step 4: Create a metric to judge success Step 5: Voice out possible solutions and go through pros / cons Step 6: Implement and Track improvement - Was it successful?
