Episode notes
Experimentation Misconceptions Rooted in History
- The majority of what's called experimentation in business today doesn't make sense due to legacy misconceptions from early A-B testing consultants.
- Experimentation is wrongly treated as a tactical revenue generator rather than a strategic innovation process.
The ROI Trap in Experimentation
- ROI calculations for A-B tests create unrealistic expectations, misleading senior management about experimentation's real impact.
- Experimentation should focus on evidence-based business innovation, not simply revenue uplift from small front-end changes.
Manage Experimentation Like Apollo Mission
- Businesses should manage experimentation as a coordinated, strategic process aligned with clear goals, like the Apollo space mission example.
- Simply running experiments or having tools is not experimentation; governance and alignment to strategy are essential.
