Audit and improve a customer cohort analysis for a customer success function

Work on the customer cohort analysis has reached the point where a customer success function needs a defined implementation and a usable handover. We need someone who can examine the existing materials, shape the working approach, and leave the team with a result they can run after delivery. The handover should make ownership, next actions, and remaining dependencies clear to people who will use the work. The project budget is €800.
