The exact change

Before

The article told the pea-pod discovery story, gave a Microsoft 80%-of-crashes figure, called the 80/20 customer rule nearly universal, cited a Gruber NEJM 2012 Medicare study, used Salesforce and Spotify as universal examples, and presented a Vodafone UK case with a named executive and 18%/76% figures.

After

Corrected the anecdote, qualified the universal claims, replaced the unverifiable NEJM citation with a sourced general statement, and generalized the fabricated-looking case studies, while keeping the verifiable statistics and studies.

Suggested change

See before/after.

Why this is better

The pea-pod story is apocryphal and several case studies and the NEJM citation could not be verified. Corrections remove or generalize the unverifiable specifics and keep the genuine ones rather than inventing sources.
