The marginal gains theory in business suggests that accumulating small, incremental improvements across various aspects of a business leads to significant overall success. It focuses on the idea that making 1% improvements in many areas adds up to a massive difference.

This concept, popularized by British Cycling’s Dave Brailsford, applies perfectly to business operations, from cutting minor costs to improving customer service response times by a few seconds. Success isn't always about one big leap; it's about constant, small steps forward.
