Transform principles into new practices: > We believe that transferring practices from one environment to another is often a mistake. Instead, one must understand the fundamental principles behind practices and transform those principles into new practices for a new environment. --p101, Chapter 5, [Lean software development (book)](https://wiki.g15e.com/pages/Lean%20software%20development%20(book.txt)) "Work-out" as a management improvement process: > At a work-out, 50 or so workers gather for two or three days and come up with proposals that will help them to do a better job. Teams come up with specific proposals for doing away with processes that get in the way and implementing practices that will deliver value faster. Before the work-out is over, managers are required to make a yes-no decision on every proposal, either on the spot or within a couple of days. Those who made proposals are expected to be responsible for implementing them - immediately. The combination of simple tools, immediate action, and participation of virtually everyone in the company combined to make work-out a uniquely successful improvement program. > > In most improvement programs managers tell workers how to do their jobs. In work-out the tables are turned; workers tell managers how to let them do their jobs. A work-out is a process that teaches managers how to listen to workers, charter them to take action on their ideas, and follow up to be sure that approved proposals are implemented promptly. A work-out assumes that workers know how to do their jobs and focuses management attention on changing the systems that, in the eyes of the workers, prevent them from doing a good job. --p102-103, Chapter 5, [Lean software development (book)](https://wiki.g15e.com/pages/Lean%20software%20development%20(book.txt))
