Thing is, Scrum doesn't work for most of the organization. Sales use a sales funnel as their guiding organizational tool. IT operations and support do reactionary work on incoming tickets, and some rather routine and planned projects. HR is almost all routine paperpushing. Legal has to take the time it takes to answer the questions they get, because they have to answer correctly. Market analysis is timeboxed analysis - a spike in agile lingo. Hardware design is innately waterfall. Hardware production is just mindless repetitiveness as fast as you can go... and so on... They're all different!
