First-Mover Advantage

Overview

Lieberman and Montgomery's 1988 landmark paper established both the mechanisms of first-mover advantage and, with equal rigor, the mechanisms of first-mover disadvantage that make late entry rational and sometimes superior. The three advantage sources are: (1) technological leadership, (2) preemption of scarce assets, and (3) buyer switching costs. The three disadvantage mechanisms are: free-rider problem, resolution of market/technology uncertainty, and incumbent inertia. First-mover advantage is not a fact to assert — it is a structural condition to diagnose.

When to Use

Apply when: deciding to enter now or wait · assessing how defensible a market leader's position is · a late entrant maps where the pioneer is weakest · a first mover audits which accumulated advantages are durable · gauging whether an AI-native pioneer's lead survives fast-followers, AI capex escalation, or accelerating AI adoption.

When NOT to use: No one has entered yet. The core question is execution quality, not timing. The advantage claimed is brand/momentum alone with no structural lock-in mechanism.

Engine mode: specific market + named pioneer + strategic question → run The Process. Coach mode: "what is FMA / should we move first?" → guide step by step. In Coach mode, respond one step at a time. Each [WAIT] is a hard stop — output only that step's question, then stop.
