What are the different accounting concepts and principle?
One accounting concept is based around the principles of lean thinking. This is used by companies that employ such methods as lean manufacturing, lean product development, and other lean strategies. Lean Accounting uses cost, management, and financial accounting methods that are based on lean principles. Lean Accounting supports and motivates lean thinking and lean improvement throughout an organization. This is in contrast to more traditional accounting methods that are hostile to lean thinking because they reflect the traditional management principles that are counter to lean thinking.
