EP 3 - The Conversation Gap Between Technical Experts & Business Leaders

EP 2 - Rejecting the culture of experimentation with Mark Palfreeman

Mark Palfreeman, Senior Business Intelligence Manager at Flutter UK and co-founder of Experimentation North, joins Efestra's Manuel da Costa to challenge the industry's obsession with "culture of experimentation."

Through candid discussion about challenges, trust gaps between experiment results and business reality, and the dangerous democratization of testing without proper governance, this conversation reveals why most "mature" experimentation programs are busy but not valuable - and what organizations should focus on instead.
