What is KPI (Key Performance Indicator)?

Turkish: KPI

A KPI is a critical performance indicator used in decision-making that evaluates how well a business is achieving its strategic goals.

What is a KPI?

A KPI (Key Performance Indicator) is a measurable signal chosen to track whether a goal is being achieved. Not every metric is a KPI; a KPI is tied to a decision, a target, and an accountable owner.

A useful KPI has a clear formula, data source, measurement cadence, target value, and responsible team. “Monthly sales” may be a metric; “increase enterprise opportunity-to-contract conversion to 18%” is a more actionable KPI. KPIs can measure outcomes, but they can also track process quality: delivery time, issue resolution time, active usage, or customer satisfaction.

Business Use

  • Sales teams tracking conversion rate, average deal size, and pipeline health
  • SaaS products monitoring churn, MRR, active usage, and onboarding completion
  • Operations teams watching on-time delivery, SLA breaches, and work backlog
  • Marketing teams measuring acquisition cost, organic traffic, and campaign conversion

KPI design should avoid vanity metrics: numbers that look impressive but do not change decisions. KPIs are commonly presented on a dashboard, analyzed through BI, and supplemented with customer-experience signals such as NPS.
