By the way, in the manufacturing industry, activities to increase productivity are also important. Of these, we sometimes pay attention to "variation" such as "variation in work", but the work flow and mechanism are the fundamental part.
A business flow is a diagram that shows the business flow and structure.
The flow of work in the company is extremely complicated, and even if only the person in charge knows, or even if he knows the part he is in charge of, what is his input and why is the output destination? You may not know much if you are there.

There are two points to focus on to find problems and improvements from the workflow.
It may be an improvement if there are many exchanges between the two departments.
An analysis performed by the IE method , PERT , and Theory of Constraints .
If each process proceeds in the same time, there will be no problem even if work comes in one after another, but if there is a part that takes time even in one place, the overall speed will be decided by that part. increase. Finding this part is the goal of the analysis.
