The Error Coefficient: A Must-Read Book for Event Production Professionals

At All On Stage, we're proud to work alongside some of the most knowledgeable professionals in the event production industry. One of our team members, André Lazarini Ferreira, recently published a book that we think every event planner, production manager, and AV professional should read.

The Error Coefficient: The Mathematic of Success in Events tackles something every veteran in this industry knows intuitively but rarely talks about openly — how small, seemingly insignificant mistakes accumulate until they reach a breaking point. The concept is straightforward but powerful: every risk factor in an event carries a percentage. A loose bolt, a distracted technician, an untested cable. Individually they seem minor. But when those percentages add up to 100%, failure becomes inevitable. André calls this the Error Coefficient. The book covers technical errors, human errors, financial and logistical errors, communication breakdowns, safety failures, digital event challenges, and even cultural errors — a comprehensive look at every dimension of event risk. It closes with real case studies and a practical Event Risk Map.

After 20+ years producing events across South Florida, this framework resonates deeply with how we operate at All On Stage. Owning 100% of our equipment, keeping experienced technicians onsite throughout every event, conducting thorough pre-event checks — these aren't just good practices, they're how you keep the Error Coefficient low. Whether you're an event planner, a corporate AV buyer, or a production professional, this book will change how you think about event risk.
