Fighting Inertia: Obstacles to Adoption and Use

Definition

Inertia is the default state customers rest in even when a better option exists: a genuinely superior product does not sell itself, because switching has its own cost and people will look for reasons not to change. The book names ten recurring, specific obstacles that operate at two different moments — obstacles to adoption (barriers to the first purchase, such as lack of knowledge, required behavior change, multiple decision-makers, high cost, high risk, or an unfamiliar category) and obstacles to use (barriers to continued use after purchase, such as missing supporting infrastructure). Naming which specific obstacle is blocking a product tells you which specific lever to pull.

In the Book

Chapter 5 opens with a woman living in an apartment with literally no kitchen, who nonetheless never got around to moving because "other things came up" — inertia beating even an acute, obvious need. The chapter's extended case is mopeds versus cars in U.S. cities: despite comparable traffic and hassle to markets where mopeds thrive, American consumers default to cars because of perception and comfort, and GenZe's electric scooter (the GenZe 2.0) was engineered against that specific inertia — rainproof cargo units, a 7-inch touchscreen, taller windscreens, and a beginner driving mode, all aimed at named adoption obstacles rather than generic "better design." The ten obstacles are each grounded in a distinct example: lack of knowledge (physicians not realizing the cost of messy paper medical records), behavior-change requirement (Ozon's e-reader struggling in Russia's cash-based economy), multiple decision-makers (hospital systems needing IT, department, and physician buy-in simultaneously), high cost (a $40,000 diamond-studded Nesmuk knife; carrier termination fees), high risk (slow uptake of patent litigation insurance for fear of inviting suits), unfamiliar category (IoT vendor en-Gauge entering through the familiar, budgeted niche of fire-extinguisher monitoring rather than "IoT" broadly), and, for continued use, limited supporting infrastructure (electric vehicles stalling on a lack of charging stations; a peer-to-peer app with no peers).

Why It Matters

Distinguishing "the product isn't good enough" from "a specific, named obstacle is blocking adoption or repeat use" changes what a team spends its next dollar on. Most product failures aren't failures of the underlying idea but failures to anticipate one of a short, recurring list of frictions — which means the fix is usually not a better product but a smaller ask: lower the cost of trial, reduce the number of people who must agree, or build the missing supporting infrastructure first.
