What Is a Product Flow Diagram?
The process flow chart uses a certain symbol to show the actual process in a graphical manner, in order to determine the form of possible variables. It can have a comprehensive and unified understanding of the process to be improved; help the project team determine all the variables that are controllable and uncontrollable in the process, as well as possible defects.
- Use the process flow diagram to explain the entire process of product (service) formation. In order to explain all possible fluctuations in the process, all human resources, documents, program methods, equipment and measuring instruments should be included in the process description.
- Process flow diagrams should use standard or recognized graphical symbols (or languages) and structures to draw process flow diagrams. The commonly used symbols for drawing flowcharts are as follows:
- The ellipse symbol indicates the terminal. It indicates the beginning (input) or end (output) of a process. "Start" or "End" is written in the symbol; the rectangular symbol indicates the activity. It represents a separate step in the process, and a brief description of the activity is written in a rectangle; the diamond symbol indicates judgment. It represents a decision or a [1] in the process
- 1.Check each decision symbol
- Is this an inspection activity? Is this a comprehensive check? Or just check for a few types of faults? Is this a redundant check?
- 2.Investigate each cycle
- If there are no failures, do these activities need to be done? How long are the cycles (steps, time lost, resources lost)? Can this cycle prevent the problem from happening or happening again?
- 3.Analyze each activity symbol
- Is it a lengthy event? What is the cost / benefit of the activity? How can we prevent mistakes in this event?
- 4.Research each file or data symbol
