This document summarizes an experiment conducted with teams at a company to test self-organizing principles. In the experiment, called a "No Management Sprint", mature teams were given autonomy with minimal rules while younger teams struggled. Mature teams thrived, completing their work on time while also taking on additional improvement projects. Younger teams had difficulties and felt stressed without clear direction. Based on the results, the document recommends only using this approach periodically with mature teams and with management endorsement.
