A retention chart is a starting point rather than a verdict. Define the return behaviour around the product's natural rhythm, separate new and established users, and compare meaningful segments. Bring qualitative context into the review. The best outcome is a testable explanation and a clear next action—not another permanent chart.
Put the idea to work
Write down the decision this analysis should change, the evidence that would challenge your current belief, and the person responsible for acting on the result. These three details keep exploratory work connected to a useful outcome.
When definitions change, record why and from which date. Consistency is valuable, but transparent evolution is more trustworthy than preserving a metric that no longer represents the product.
