time, to maintain a full workload, we can do a lot of work every day basically is certain, so the throughput rate basically does not change too much.If at this time we want to shorten the average lead time, which is the waiting time, the law of Delphi tells us that this goal can be achieved by reducing the number of WIP.In this case, the number of people queuing is reduced.
It is also well understood that the queue of 10 people and the queue of 20 people, the former need to wait for a shorter t

I heard many people say: "We are doing agile development. Every release is divided into multiple iterations for development ."
However, I found that at the end of each iteration, the developed software could not meet the quality requirements of "launch", and even the software could not run.
