What Are Key Performance Indicators In Businesses

What Are Key Performance Indicators, and Why Do Most SMEs Get Them Wrong?

A Key Performance Indicator (KPI) is a specific, measurable figure that tells a business whether it is on track against a goal that matters to its performance. Used well, KPIs give directors an early, reliable signal of what's working and what needs attention, well before the problem shows up in the monthly accounts. Used badly, or when they're missing altogether, decisions end up being made on instinct rather than evidence.

In Secantor's experience working with owner-managed businesses, this is far more often the reality than not. Most businesses either have no meaningful KPIs in place at all, or the ones they do have are poorly chosen, rarely reviewed, or disconnected from the decisions they're supposed to inform.

What Makes a Good KPI?

A good KPI has three characteristics. It is directly linked to a decision the business needs to make, not simply interesting to know. It is reviewed regularly enough to actually influence that decision, rather than surfacing the information too late to act on. And it has an owner: someone accountable for the number moving in the right direction, not just for reporting it.

A useful test is this: if a KPI moved sharply in the wrong direction next month, would anyone notice, and would anyone change what they're doing as a result? If the honest answer is no, it's probably not a KPI worth keeping.

What Types of KPIs Should a Growing Business Track?

Most SMEs need a mix of KPIs across several areas of the business, not just finance. The right combination depends on the business, but the categories that matter most typically include:

Financial KPIs. Revenue, gross margin, net profit, debtor days and cash position, always reviewed against budget or forecast rather than in isolation, so directors can see deviation from plan and take corrective action.

Sales KPIs. Enquiries, quotes, conversion rate, order book and sales performance by customer, product or territory. These give an early view of where revenue is heading, often weeks or months before it appears in the financial results.

Operational KPIs. Productivity, capacity, on-time delivery, quality and cost per unit, depending on what actually drives performance in that business. These tend to be the earliest warning signs of a problem, since operational issues usually surface before they affect the numbers.

Other functional measures. Depending on the business, this might include people metrics such as staff turnover, marketing metrics such as lead generation cost, or sector-specific measures such as health and safety performance. Not every business needs every category. The right mix reflects what actually drives that business's results.

It's also worth distinguishing between leading and lagging indicators. Lagging indicators, like revenue or profit, tell you what has already happened. Leading indicators, like sales pipeline or quotation conversion rates, help predict what's coming next. A well-balanced set of KPIs includes both, since lagging indicators alone only ever confirm a problem after it's too late to prevent it.

How Many KPIs Should a Business Have?

Fewer than most business owners expect. A common mistake growing businesses make is assuming that more measurement automatically means better management. In practice, the opposite is usually true: a long list of KPIs that nobody reviews consistently is worse than a short list that's genuinely acted on every month.

There's no fixed number that suits every business, but a useful discipline is to limit KPIs to the handful of measures that would change a decision if they moved. Everything else can still be monitored at an operational level without needing to sit on the board-level dashboard.

How Should KPIs Be Used in Practice?

KPIs work best when reviewed alongside monthly management accounts, not as a separate exercise. Reviewing the numbers together gives directors both the financial outcome and the operational drivers that produced it, which is usually where the useful insight sits. Our Management Information knowledge page sets out how this fits into a wider management information framework as a business grows.

Each KPI should have a named owner accountable for it, and below-target performance should trigger a clear corrective action, not just a note in the board pack. Trend data matters more than any single month's figure; presenting KPIs on a rolling basis, such as the last 12 months, makes it far easier to spot a genuine pattern rather than reacting to one unusual month.

This is a pattern Secantor sees consistently across decades of hands-on work with hundreds of SME businesses: the businesses that get the most value from KPIs are the ones that review a small, well-chosen set regularly and hold people accountable to them, not the ones with the most sophisticated dashboard.

Frequently Asked Questions

What is a Key Performance Indicator?
A Key Performance Indicator is a specific, measurable figure that shows whether a business is on track against a goal that matters to its performance, reviewed regularly enough to actually influence a decision.

How many KPIs should an SME track?
There's no fixed number, but most businesses get better results from a small, carefully chosen set that's genuinely reviewed and acted on, rather than a long list that receives little attention.

What's the difference between a leading and a lagging indicator?
A lagging indicator, such as revenue or profit, shows what has already happened. A leading indicator, such as sales pipeline or conversion rate, helps predict what's likely to happen next. A good set of KPIs includes both.

How often should KPIs be reviewed?
Most owner-managed businesses benefit from reviewing KPIs monthly, alongside management accounts, with certain measures such as cash or sales pipeline reviewed more frequently depending on how quickly they can change.

Do KPIs need to be financial?
No. Financial KPIs are only part of the picture. Sales, operational and people-related measures often provide an earlier signal of a problem than the financial results alone.
