KPI
Also: KPI, Key Performance Indicator, performance indicator, indicateur clé de performance, ICP
Key Performance Indicator, a measurable value that shows how effectively you're achieving a specific objective, tracked over time against a target.
What it is
A Key Performance Indicator (KPI) is a quantifiable metric that measures how effectively an organization, team, or individual is progressing toward a specific objective. The word key is deliberate: out of the hundreds of metrics you could track, a KPI is one you have chosen because it directly reflects success on a goal that matters.
A useful KPI has three parts:
- A metric (what you measure, for example conversion rate)
- A target (the value you aim for, for example 4 percent)
- A time frame (over what period, for example this quarter)
Without a target and a time frame, a number is just a metric, not a KPI.
Why it matters
KPIs turn strategy into something observable. They align teams around shared definitions of success, make progress visible, and support decisions with evidence instead of opinion. They also expose problems early, while there is still time to react.
Good KPIs share a few traits, often summarized as SMART: Specific, Measurable, Achievable, Relevant, and Time bound.
How it is used in practice
- Define the objective first, then choose the KPI that best signals progress toward it.
- Set a baseline from historical data so you know your starting point.
- Assign a target and a review cadence (weekly, monthly, quarterly).
- Distinguish leading from lagging indicators: leading KPIs predict future results (for example qualified pipeline), lagging KPIs confirm past results (for example revenue).
- Avoid vanity metrics: numbers that look impressive but do not drive decisions.
- Limit the count: a dashboard with 40 KPIs has none. Focus on a handful per objective.
Worked example
A subscription business sets the objective reduce customer churn.
- Metric: monthly churn rate = customers lost in month / customers at start of month
- Baseline: 5.0 percent
- Target: 3.5 percent within two quarters
- Cadence: reviewed monthly
In March, 40 of 1,000 customers cancel, giving a churn rate of 4.0 percent. The team is moving toward the target but not there yet. Because churn is a lagging KPI, they also track a leading KPI (product logins per active account) to anticipate churn before it happens.
The KPI does not fix churn by itself; it tells everyone, in one agreed number, whether current efforts are working.
