Updated on 24 October 2026. Every business has dozens of things to manage, but only a handful truly decide whether it succeeds. Those are its critical success factors. Here is what the term means, where it came from and how to use it.
What are critical success factors?
Critical success factors (CSFs) are the limited number of areas where things must go right for an organisation, team or project to reach its goals. If performance in these areas is poor, the goal is likely to be missed, however well everything else goes.
The idea was popularised by John F. Rockart of the MIT Sloan School of Management in a 1979 Harvard Business Review article on how chief executives could define the information they really needed.

Examples of critical success factors
| Business | Possible critical success factors |
|---|---|
| Restaurant | Food quality, location, speed of service |
| E-commerce brand | Product quality, delivery speed, customer acquisition cost |
| Software start-up | Product-market fit, user retention, team quality |
| Hospital | Patient safety, specialist availability, waiting times |
| School | Teacher quality, results, parent trust |
CSFs vs KPIs
The two are related but not the same:
- A CSF is what must go right. For example, “fast delivery”.
- A KPI measures how well it is going. For example, “percentage of orders delivered within two days”.
Each CSF usually has one or more KPIs attached, so you can track it.
How to identify your critical success factors
- Start with your goal. Be specific about what success looks like this year.
- List what must go right. Ask which activities, if they failed, would sink the goal.
- Keep the list short. Most teams should have three to six CSFs. If everything is critical, nothing is.
- Attach a KPI to each. Decide how you will measure it and how often.
- Review regularly. CSFs change as markets and goals change.
Common mistakes
- Listing too many factors, which spreads attention thin.
- Confusing tasks (“post on social media”) with factors (“brand awareness among target customers”).
- Setting CSFs once and never revisiting them.
