Other forms: expediences
Having the quality of expedience means that something is efficient and gets results — but it's not necessarily ethical.
If a business owner prioritizes expedience, that means she neglects things like safe working conditions and quality products in order to produce goods quickly and make a fast profit. In politics, expedience can mean making false promises or using short-term solutions to deeper problems, with the aim of getting elected (or reelected). "Filling those potholes right before election day looks to me like political expedience on the Mayor's part."
