You're familiar with the conversion metrics funnel. Here, you can optimise and measure UX. Certain parts are more important to you. Here's the humanised, experience-translated version.
Acquisition: I get you. I understand you.
Activation: I'm a BIT curious. I can act.
Retention: You fit into my life. I feel intuitive. I know that I will be supported.
Referral: You delight me. You make me laugh. You show that you know me well.
Revenue: I trust you. Your product and packaging is for me.
