Adoption Half-Life

Adoption Half-Life is the rate at which learner engagement in a training program decays after launch, and it is the number that decides whether an LMS retainer survives its second renewal. Most agencies sell the build: course libraries, portals, compliance paths. The decay curve is what clients actually experience. A program that hits 80% completion in month one and 20% by month four reads to the buyer as a failed deliverable, regardless of how well the content was authored. The framework asks three questions before scoping: who owns the nudge cadence after handoff, what triggers a refresh, and which metric proves the decay is slowing. LearnUpon bundles AI-assisted authoring that claims 90% faster course creation, which shortens build time but does nothing for month-four engagement. Absorb LMS supports multi-tenant delivery and white-label reselling, so agencies carrying several client academies feel the decay multiplied across accounts. Price the maintenance layer, not just the build.
