Follow the cohort over time: Track the cohort over time, collecting data at regular intervals (e.g., monthly, quarterly, or annually).
-
Analyze the data: Analyze the data to identify any changes in the cohort over time. This may include changes in behaviors, trends, or other characteristics.
-
Draw conclusions: Draw conclusions from the analysis and use the data to inform decision-making.
