  3. 3. www.citoolkit.com Flow Process Chart A symbolic representation that illustrates the sequence of activities within a process
  4. 4. www.citoolkit.com Flow Process Chart Used to analyze and record the activities that make up a process to determine which steps add value and which do not Allows us to focus on the value-added activities
  5. 5. www.citoolkit.com Flow Process Chart Often includes the activities of an individual, a team, a machine, a computer system, or combinations of all
  6. 6. www.citoolkit.com Flow Process Chart Preferred over other process mapping techniques when the process is sequential in nature and contains few decision points Some time it referred to as Process Sequence Chart
  7. 7. www.citoolkit.com Flow Process Chart A useful feature of the flow process chart is that it can be drawn up as the process is happening So it provides an accurate description of the process
  8. 8. www.citoolkit.com Flow Process Chart By watching and recording, a person for example can follow a part, noting how and when it is produced, moved, checked and stored This ensures that what is actually happening gets recorded
  9. 9. www.citoolkit.com Flow Process Chart Later when analyzing the process, some steps become obvious candidates for improvement, such non-value-adding activities, long delays and excessive transportation
  10. 10. www.citoolkit.com Flow Process Chart Used to show all the operation, inspection, storage, transportation, and delay activities that exist in a process From order-taking through scheduling to delivery From raw material through production to the hands of the customer From concept through detailed design to product launch From the receiving through the plant to the shipping
  11. 11. www.citoolkit.com Flow Process Chart Can be used to analyze value-added and non-value added activities NVA Step 3 ENVA Step 2 VA Step 1 Helps identifying waste, long delays and other non-value-added activities
  12. 12. www.citoolkit.com Flow Process Chart Benefits Track performance measures such as time, distance traveled and error rates
  13. 13. www.citoolkit.com Flow Process Chart Benefits Costing the present and future charts will be required to justify any future improvement proposal
  14. 14. www.citoolkit.com Flow Process Chart It records the steps of a process along a vertical or horizontal line
  15. 15. www.citoolkit.com Flow Process Chart The process activities are displayed using common symbols along with text Waiting Inspecting ReceivingSymbols to indicate the type of activities being undertaken Text to briefly describe the activities
  16. 16. www.citoolkit.com Flow Process Chart Common symbols are . . . Operation Inspection Storage Transport Delay These symbols have been accepted by many Lean practitioners and organizations Other categories and symbols can be used depending on the situation
  17. 17. www.citoolkit.com Flow Process Chart Common symbols are . . . Produce, add, change, or process something.Operation Checking of items for quality and/or quantity.Inspection The storing of items until later time.Storage The movement of items or people between areas.Transport The temporary waiting of something or somebody.Delay
  18. 18. www.citoolkit.com Flow Process Chart Common symbols are . . . Produce, change, add or process something.Operation Examples: Drilling a hole in metal and serving a customer at a call center.
  19. 19. www.citoolkit.com Flow Process Chart Common symbols are . . . Checking of items to ensure correct quality and/or quantity. Does not add or change anything. Inspection Examples: Checking for defects, measuring the dimensions of a product, counting a received products, and getting feedback from a customer.
  20. 20. www.citoolkit.com Flow Process Chart Common symbols are . . . The storing of something until later time.Storage Examples: Storing of finished goods in a warehouse, and storing of the received supplies in a storeroom as inventory.
  21. 21. www.citoolkit.com Flow Process Chart Common symbols are . . . The movement of people, materials, documents, tools, or other items from one location to another. Transport Examples: A forklift moving pallets from a warehouse into a loading bay, a conveyer carrying a partially completed product from one machine to the next, and a customer walking from sales floor to cashier Methods can be: • Truck • Forklift • Crane • Trolley • Conveyer • Hand
  22. 22. www.citoolkit.com Flow Process Chart Common symbols are . . . The temporary waiting of something or somebody.Delay Examples: The time spent waiting for maintenance and repair activities, and the time the customer spent waiting in a queue. O R D E R
  23. 23. www.citoolkit.com Flow Process Chart Value-Added Activities and Waste Only operations will add value (BUT not all operations!) Inspection, storage, delay, and transportation activities will add no value from the customer's viewpoint Operation Inspection Storage Transport Delay
  24. 24. www.citoolkit.com Flow Process Chart Other symbols . . . Rework or scrap point Decision Longer-term storage (or when storage is larger than a container) Inspection while operating Operating while transporting Operating while being in storage
  25. 25. www.citoolkit.com Flow Process Chart Care should be taken when choosing the right category, as a delay of a machine could be an inspection made by an operator or a transportation activity
  26. 26. www.citoolkit.com Flow Process Chart There are three common types of flow process charts, based on what is being charted . . . Material-Type Charts Equipment-Type Charts Man-Type Charts
  27. 27. www.citoolkit.com Flow Process Chart Man-Type Charts Shows the actions of a person or group of people Take samples To QC station Inspect samples Enter results into spreadsheet Wait report to be printed S amp les In sp ec tion
  28. 28. www.citoolkit.com Flow Process Chart Material-Type Charts Shows what happens to a product or item as it moves Enter invoice into system 15 minutes Match invoice to PO 10 minutes Send for authorization 5 minutes Wait payment authorization 60 minutes Back to Accounts 5 minutes Pay the supplier 30 minutes S u p p lier Invoic e Proc essin g
  29. 29. www.citoolkit.com Flow Process Chart Equipment-Type Charts Shows how a tool or an equipment is used Use of an offic e copy mac h in e Warming up Waiting to place papers Producing the photocopies Waiting to be turned on Waiting to press the copy button
  30. 30. www.citoolkit.com Flow Process Chart A good practice is to chart the present process as well as the future (proposed) process in order to drive change and continuous improvement AS IS TO BE
  31. 31. www.citoolkit.com Flow Process Chart The typical approach is that the present method is recorded on a chart through direct observation, and then the improvement will be proposed on a second chart
  32. 32. www.citoolkit.com Flow Process Chart When charting the future chart, each step is subject to . . . Elimination Combination Change sequence
  33. 33. www.citoolkit.com Flow Process Chart The time for each process step and the distance travelled should be calculated The reduction of both will help in cost reduction and will justify any improvement proposal
  34. 34. www.citoolkit.com Flow Process Chart Improvements can be achieved as a result of the reduction of the number of steps, the reduction of the time for any of the steps, and the reduction of the distance travelled 1 23
  35. 35. www.citoolkit.com Flow Process Chart How to Construct a Flow Process Chart With your team, describe the process, the scope and the boundaries Observe the process, then record the process activities as they happen Draw on a line the process activities as observed using the standard set of symbols
  36. 36. www.citoolkit.com Flow Process Chart How to Construct a Flow Process Chart Label each process step with a brief description using as few words as possible Add further details as necessary including the distance travelled, error rates, and the time take to perform each activity
  37. 37. www.citoolkit.com Flow Process Chart Identify problem areas and improvement opportunities How to Construct a Flow Process Chart Come up with the proposed chart trying to reduce waste and increase the percentage of the value added activities
