The best way to eliminate waste in Disciplined Agile is to "eliminate delays in workflow and feedback." Lean principles focus on removing any non-value-added activities (waste) to improve efficiency. By minimizing delays, teams can ensure a smoother flow of work and faster feedback loops, which helps to identify and resolve issues quickly and reduces the time taken to deliver value to customers. While making sure each step is done as quickly as possible (A) or correctly(D) and ensuring people know their job (B) are important, they are not the primary method of eliminating waste according to Lean principles.
