Business cycle

Fluctuations in economic activity over time, including expansion and contraction phases.

Definition

Business cycle is the fluctuations in economic activity over time, including expansion and contraction phases. 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.

Two cofounders disagree until they define Business cycle. Once they agree it means “Fluctuations in economic activity over time, including expansion and contraction phases”, the argument becomes a decision.

Common mistake

Using Business cycle 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.
