In Simple Words
Traditional business training is like giving someone a thick textbook covering twenty different sports all at once during a short one-week workshop. Because the material is broad, generic, and fast-paced, participants remember a few basic rules initially but quickly fall back into old routines once daily business pressures return.

- 12.1% higher profits on average
Meta-analytic average across traditional-training comparisons, with different programs and follow-up periods. The average does not establish lasting gains in every setting.

Standardized classroom-based business courses attempt to teach broad managerial topics—such as financial management, marketing, and accounting—in general group settings. However, microentrepreneurs struggle to absorb dozens of distinct practices simultaneously and frequently revert to prior habits over time.
Participants
Human microentrepreneurs across low- and middle-income countries evaluated in 28 randomized trials (representing a global field where at least US$1 billion is spent annually to train 4 to 5 million microentrepreneurs).
Study Design
Meta-analysis of 28 Randomized Controlled Trials (RCTs) measuring business practice adoption, sales, and profits over short- and long-term horizons.
Results
Traditional training yielded modest average sales increases of 5.6% and profit increases of 12.1%; practice adoption faded within 4 months in Kenya and within 1 year in Ghana, while an all-day week-long course in Sri Lanka increased practice use for 2 years without generating detectable profit gains.
Takeaway
Replace multi-topic general classroom lectures with narrow, focused modules that target single, actionable operational problems.
