Key driver

Primary factor that influences or determines the success of a business or project.

Definition

Key driver is the primary factor that influences or determines the success of a business or project. 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.

In the room

How the word shows up in a real conversation.

A mentor asks, “What is your Key driver?” The useful answer is concrete: primary factor that influences or determines the success of a business or project. A slide title is not an answer.

Common mistake

Using Key driver 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.
