KPIs, MBOs and SMART goals are often mentioned alongside OKRs, but each does a different job. KPIs monitor the health of the business. MBO is an older, annual and pay-linked way to set individual goals. SMART is a checklist for writing a single goal. OKRs are a quarterly system that focuses teams on the few outcomes that need to change.
OKRs vs. KPIs: change vs. health
- KPIs (Key Performance Indicators) are like the gauges on a car's dashboard. They track the ongoing health of business-as-usual work, such as uptime, revenue or tickets closed, and they stay in place year after year.
- OKRs define where you want to go next. You set an OKR to change something, not to maintain the status quo.
The two work together. A KPI that turns red often becomes the focus of an OKR. If customer retention drops, a team might set the Objective "Give customers a reason to stay" with the Key Result "Improve customer retention from 85% to 92%". Once the KPI is healthy again, it goes back to the dashboard.
OKRs vs. MBOs: the modern evolution
OKRs grew out of Management by Objectives (MBO), but they fix its main weaknesses:
- Cadence: MBOs are usually set and reviewed once a year. OKRs run quarterly, so teams can adapt.
- Transparency: MBOs are private between a manager and an employee. OKRs are visible across the company, which makes alignment and collaboration possible.
- Direction: MBOs flow top-down to individuals. OKRs combine company direction with teams writing their own OKRs.
- Compensation: MBOs are tied to bonuses, so people set safe targets. OKRs are kept separate from pay so teams can aim high.
- Scoring: MBOs are judged as met or not met. OKRs are scored on a scale, and reaching about 70% of an aspirational Key Result counts as a good result.
OKRs vs. SMART goals: system vs. checklist
SMART (Specific, Measurable, Achievable, Relevant, Time-bound) is a checklist for writing one well-defined goal. OKRs are a system: a qualitative Objective that explains why something matters, 2 to 4 Key Results that prove it happened, and weekly check-ins to steer.
The two are not rivals. Every good Key Result should pass the SMART test. The difference is ambition: SMART asks for achievable goals, while OKRs deliberately include aspirational targets that push beyond business as usual.
What all good goals share
Whichever method you use, measure outcomes, not activities. "Publish 8 blog posts" is an activity. "Grow organic sign-ups from 300 to 450 per month" is an outcome. OKRs make this distinction central, which is the main reason they turn strategy into results.
