“Is it robust — do you have a value promise solving a real pain point? Is it delivered rapidly — can you get someone to the aha moment in the first 30 seconds? Is it repeatable — will users keep getting value month after month? And is it remarkable enough that people talk about it and build a community around it?”

Value creation needs four Rs: Robust, Rapid, Repeatable, Remarkable

Carter's four-part framework for evaluating the value creation step. Robust = real PMF (40% test). Rapid = aha moment in first session. Repeatable = ongoing utility that justifies recurring billing. Remarkable = organic word of mouth that compounds acquisition. Each R has its own measurement tools and common failure modes — and missing any one of them creates a predictable ceiling.
