I had the opportunity to participate in the course this week and can confirm that it is in fact a game changer (like Essence itself). After attending this course, you will see the software engineering method industry with different eyes. Essence puts Scrum (and any other practice/ method) into perspective. Existing software development frameworks and methods are suddenly dwarfed. They are just one piece of the puzzle. Thus, there is a necessity for an ecosystem of software engineering practices which includes the practices from nearly all frameworks and can be used to select and adopt the practices needed for a specific software development endeavor. Eventually you will see that single and isolated methods/ frameworks guarded by individual persons/ organizations do not make sense.
