What I appreciate about Scrum and other methodologies is that it can be used as a starting point from which customization and adaptation can grow, rather than starting from practically no documentation or process and building a monster of a system that ends up mostly fitting the existing broken system.
Yes, exactly. That's why I advocate starting with some known process, even if you modify it. Starting from scratch, IME, tends to lead to just creating a non-coherent mess.
