# Market Entry Decision Framework for Diversified Firms

## Framework: Market Entry Decision for Diversified Firms

A three-gate sequence for a diversified firm deciding whether and how to enter a market. Which gate is decisive depends on where the target sits on the [[framework-competitive-intensity-model]].

### The three gates

1. **Assess Synergies** *(always applies).* Can you serve customers better or at lower cost than competitors using *simultaneous* resource sharing? This is the standard diversification check — see [[concept-synergy-vs-redeployability]]. Synergies help at every intensity.
2. **Evaluate Ramp-Up Speed** *(decisive at medium intensity).* Ask: *'Can you ramp up your resource/market position faster than competitors?'* Crucial in medium-intensity markets to establish a strong position early and deter entry. This is the operational lever behind [[action-assess-ramp-up-speed]] and rests on [[claim-medium-intensity-favors-flexibility]].
3. **Evaluate Commitment Credibility** *(decisive at high / winner-take-all intensity).* Ask: *'Can you credibly commit to defend your resource/market position, whatever it takes?'* Crucial in winner-take-all markets. **If the honest answer is no**, either engineer commitment via [[concept-structural-separation-commitment]] (see [[action-structural-separation]]) — or abandon entry.

### Companion action

Before entering, run [[action-evaluate-retreat-signals]] to check whether your inherent flexibility reads as a willingness to retreat. If it does, and you cannot pass Gate 3, do not walk into a war of attrition you are structurally primed to lose (cf. [[entity-google-d1]] in Google+, [[entity-uber-d116]] in China).
