Work less, achieve more: The secret of the 80/20 rule

80% of your results come from 20% of your efforts? Great. So why are you still micromanaging the other 80% like it's sacred? There is this belief that hard work will always result in success. But that's not always the case. The Pareto principle (the "80/20 rule") reminds us that a small portion of inputs (customers, features, processes) usually generates the majority of the outcomes.

Time, energy, knowledge, money: all these things have their limits. Scattering all of it on 100% of an issue leads to burnout and big losses. The Pareto principle helps you understand and categorise the data, so you can properly invest your resources and efforts.

The Pareto principle explained

Italian economist Vilfredo Pareto first observed this phenomenon over a century ago, with peas in his garden. Joseph Juran has adapted this thinking in management and business, focusing on the "vital few and the useful many". It's not a law but a common pattern; sometimes it can be split into 70/30, 90/10, etc.

The core idea is that a minority of causes produces a majority of effects. For example, 80% of a company's sales often come from just 20% of its clients. The question you need to ask yourself is: Are you focusing on the high-impact few or diffusing your energy across too many low-impact areas?

Examples of the Pareto principle

SaaS & product development: Roughly 20% of software features deliver 80% of the usage and value. The flip side is that companies often waste effort on maintaining the other 80% of features that few users care about.

Customers & revenue (finance): A small fraction of customers or investors usually account for the bulk of financial results. For instance, 20% of customers often generate 80% of revenue profits.

The point here is to identify your "vital few": the key customers, products, features, services, or processes that disproportionately drive outcomes. It's easy for teams to get caught up in the trivial many tasks and lose sight of where the real value comes from.

Using data to drive decisions

Harnessing data and analytics is critical in pinpointing what actually moves the needle in your business. There is a wealth of data, but you need well-designed systems and metrics to separate signal from noise.

Conducting a Pareto analysis on your metrics can help discern the vital few from the trivial many and prioritise actions. For example, analytics may reveal which small set of features drives the most user engagement, which 2 out of 10 marketing channels generate 80% of leads, or which operational bottlenecks create most delays. You could also visualise it with a Pareto chart or dashboard.

If decisions aren't stemming from clear contribution metrics, focus may be diluted. Without knowing your Pareto drivers, it's easy to overinvest in places where benefits are small. The result is often tech complexity without commensurate value: lots of projects, features, or expenses that add up to little overall improvement. To escape this trap, build dashboards and reports that highlight the top contributors for key metrics. Let data inform where effort delivers real returns.

Assessing the situation with Pareto

First, ask yourself this important question:

What are the features/processes that generate the majority of your margin and customer retention?

If you can't readily answer this, your focus is probably scattered. Organisations that lack clear contribution metrics often fall victim to "initiative overload", working hard but not achieving proportional results. When you know what drives the bulk of your success, you can double down on those areas and confidently deprioritise the rest.
