3 A symbolic representation. Illustrates the sequence of actions within a process. Records the steps of a process along a vertical line. Used when analyzing the steps in a process. Helps identify and eliminate waste. Sometimes called process sequence chart.

4 It can be drawn up as the process is happening. This allows getting an accurate description of the process. A person for example can follow a part, noting how and when it is produced, moved, checked and stored. This ensures that what actually happens gets recorded. Later when analyzing the process, some steps become obvious candidates for improvement such as: Non-value-adding activities. Long delays. Excessive transportation.

5 -- Flow Process Chart Common Process Problems: Non-value adding steps. Errors and rework. Unnecessary activities and duplication. Bottlenecks. Long cycle times and excessive delays. Missing and unclear steps. Too many inspections or checks. Complex procedures. Departure from procedure. Dead ends. Costly steps. Muda

6 Common Symbols: Operation produce or process something. Inspection checking of items to ensure correct quality or quantity. Storage storing materials or other items. Transport movement of people, materials or other items. Delay idle time of people, material or machinery. Operation Transport Inspection Delay Storage Rejection point

7 Three Types: A man-type chart which shows the actions of a person. A material-type chart which shows what happens to a product or item. An equipment-type chart which shows how a tool or other piece of equipment is used.

8 Example Material Type Chart Egg Tray Production Process: Waste paper in store Inspecting and counting Convey to mixer Staking for packing Pulping and mixing Packing Convey to forming machine Convey to warehouse Forming Egg trays in store Drying

9 Example Supplier Invoice Processing: 15 minutes 10 minutes 5 minutes 60 minutes 5 minutes Enter invoice into system Match invoice to purchase order Send for authorization Wait for payment to be authorized Bring back to the Accounts Office 30 minutes Pay the supplier

10 Example Supplier Invoice Processing: Step # Time (min) Distance (meters) Step Description 1 15 X Enter invoice into system 2 10 X Match invoice to purchase order X Send for authorization 4 60 X Wait for payment to be authorized X Bring back to the Accounts Office 6 25 X Pay the supplier

11 Example Supplier Invoice Processing: Number of steps Time (min) Distance (meters) Operation Transport Inspection Delay Store

12 -- Flow Process Chart Further Information: What do we think of a process is not necessary what it actually is. What you think it is What it actually is What you would like it to be Hidden factors
