This document discusses different levels or stages and provides a hyperlink to a website with information about those levels. It also lists several references to the same case study from 2013 about implementing Kanban in an enterprise setting, written by Mattias Skarin. The document focuses on stages or levels and cites the same case study multiple times.

In summary, most of the "hidden truths" about Nmap options provide little practical benefit to users.
