Start with the behaviour you want to change
“We need a loyalty programme” is not yet a brief. Be specific about the outcome: more repeat purchases, stronger subscription retention, higher engagement between purchases or a better reason to choose your service. That decision shapes everything that follows.
Pick one primary outcome and a small number of supporting measures. Trying to solve acquisition, retention, referrals and average order value in the first release usually produces a complicated programme that is difficult to explain.
