Elasticity

Measure of how responsive one variable is to changes in another variable.

Definition

Elasticity is the measure of how responsive one variable is to changes in another variable. Founders reach for it when a vague conversation needs a shared, specific meaning. Name it clearly, then let the next decision — a hire, a price, a test, or a pass — follow from that meaning.

How the word shows up in a real conversation.

Two cofounders disagree until they define Elasticity. Once they agree it means “Measure of how responsive one variable is to changes in another variable”, the argument becomes a decision.

Common mistake

Using Elasticity as a label instead of a fact. If you cannot point to the evidence — a number, a customer, or a written assumption — you are using the word as jargon.
