Timing is an important and critical evaluating feature in the assessing and decision of what needs to be done and how to attain it. In order to produce something you must have gone through all the necessary stages to enable the understanding of the undertaking.

First you would utilize the preliminary stage to plan, gauge estimate and predict the task and time to be done. Then there would be the elementary stage which would enable an exact time for the task to be started and completed. Then thirdly there would be a final stage of checking and revision to ensure that everything has gone according to plan. But the whole operation has to be timed and scheduled.

There is no point finishing stage two before you start stage one or doing stage three first. You must wait for each stage to start before you start another one. Once completed you can progress onto the next stage. Management meant waiting because there is a right time to do everything. Like there is no point making another hundred products before you have sold the first fifty. The fact that you can't put the cart before the horse means that everything must be done at its perfect time.
