# Evaluate Retreat Signals Before Market Entry

## Action: Evaluate Retreat Signals Before Market Entry

**Do:** Assess whether your firm's inherent flexibility signals a *willingness to retreat* to incumbent competitors.

**Expected outcome:** Prevents entering winner-take-all markets where incumbents will exploit your lack of absolute commitment through wars of attrition.

### How to run it

This is the pre-flight check ahead of the [[framework-market-entry-evaluation]]. Ask what an incumbent *sees*: if your resources can obviously be redeployed elsewhere ([[concept-resource-redeployability]]), you are broadcasting a Plan B and inviting the [[concept-commitment-paradox]]. The failure cases to keep in mind are [[entity-google-d1]] in Google+ and [[entity-uber-d116]] in China. If the signal is bad and you cannot fix it, either engineer commitment via [[action-structural-separation]] or stay out.
