The History

When David Brailsford became performance director of British Cycling in 2003, British cycling was historically mediocre. In almost a century of competing in the Olympics, the team had only one gold medal. That’s not a good track record!

Rather than looking at finding a huge breakthrough, Brailsford introduced a simple idea: “If you break down everything that goes into riding a bike and improve it by 1%, you will get a significant increase when you put them all together.”

This became known as the aggregation of marginal gains.

He didn’t just tweak training procedures, he examined everything. He was so detailed he even had the transport trucks painted white on the inside to spot dust that could affect bike performance.

He also created a culture where every small improvement was valued. This was a really important component to get everyone on board and engaged.

Brailsford rejected the “hero solves the day” philosophy that often happens in sports. He focused on systems and the philosophy that performance is rarely one big moment — it’s the accumulated benefits in many areas.

Let’s look at how to apply this approach in business.

Improve Conversions by One Percent in Many Places

Instead of completely redesigning your website, look at how to get more clarity out of your homepage headline. Improve call to action wording. Are your call-to-action buttons in the right places? Are you asking too many questions in your lead form?

Increase Response Time

If it takes you a day to get back to leads change that to one hour. Send proposals on the same day even if it means working overtime on a Friday. Speed can get you that one percent increase in bringing people to the table to talk.

Tighten Up Internal Processes

Where could your team members be more efficient? Are your processes 100% efficient for performance and time management? Most rarely are. By getting one percent of an increase in efficiency is not daunting at all.

Improve Emotional Marginal Gains

Each phase of working with a client is an opportunity to increase trust and credibility. After a deal closes, how can you improve your onboarding procedures and reduce client stress? Do you need a stakeholder to just check in with clients occasionally? Each improvement increases perceived value.

Upgrade Skills Gradually

No one can transform a company overnight. Have resources take on the improvement of one skill per quarter. Maybe your support team could compile an FAQ for the site that reduces time for support calls or your accountant could create a process to reduce time to respond to overdue invoices.

Conversion Metric Improvements

Conversion metrics are much less daunting if you are shooting for small improvements. Try a goal of increasing your close rate by two percent. Or your cost per lead by one percent. There are a lot of metrics that can be analyzed with simple goal increases.

We revised the headline copy on our website management plans page and the engagement rate increased by 400%. (In all honesty, the copy that was there before wasn’t great, but this was a simple change with good results.)

Combine Brand Value Perception Points

Practice what you preach. If you claim that you really get to know your clients and their challenges, make sure you have a process to do that efficiently and effectively. And align this with your sales communication during sales calls and with your value proposition.

Happy Employees are Productive Employees

Have regular team meetings for suggestions on improvements. Kevin Hochman analyzed everything at Chili’s restaurants and made improvements that have turned the company around.

He replaced small-hole French fry seasoning shakers with ones with large holes so cooks used fewer motions and fries were hotter when they got to the table.

He removed large and cumbersome wings stations that required employees to maneuver around them.

Don’t Treat It Like a Campaign

Using this philosophy should be simply and stress free. Remember we are talking one percent per each component here. Try for one improvement a week. Review your task list every quarter and see how you are doing.

If you improve something by one percent daily for a year look at the results!

1.01^365 = 37.78

1.01 represents getting one percent better times 365 days of the year. The result of 37.78 means you end up nearly 38 times better than where you started.

Wrapping Up

The aggregation of marginal gains reminds us that growth rarely comes from one big “aha” moment. It’s about consistently improving small details across all of your company’s operations. Over time many small improvements can equal big results.

Summary

The aggregation of marginal gains is the strategy of improving many small, controllable aspects of a business by just 1%, leading to significant overall performance gains. Inspired by David Brailsford’s approach with British Cycling, it emphasizes systems over heroics, gradual skill upgrades, efficiency improvements, better client experience, and employee productivity. Over time, these small, consistent improvements compound to produce major results.
