Replay of an extract of Philip Marris' presentation

In his conference, Philip shared his 34-year journey and explained the extraordinary impact that Eli Goldratt had on him. The realization that plants were unbalanced and therefore had bottlenecks. The fundamental importance of marketing in business-to-business industries. Eli wrote the book The Goal as a marketing tool, so how does one do TOC marketing today? Focus: learning not to do what one should not do; protecting one’s daily schedule from the horrors of bad multitasking (no mobile phone); etc. The conflict between DBR and Lean Manufacturing. The Blue Ocean of Critical Chain Project Management. The strange world of logic: Thinking Processes, Goal Trees and other dangerous habits. How and why to never waver on your TOC journey.
