  2. 2. What is the purpose of a flow chart? • It is a picture of a process • It is drawn with symbols representing different types of activities • It defines the system being studied. • It documents changes to the process.
  3. 3. Why are flow charts useful? • They provide a visual for students to see steps in a process. • They can be used as an assessment to check for student understanding. • They can help organize classrooms and minimize transition times.
  4. 4. Flow Diagram Definition  A flow diagram is a graphical means of presenting, describing, or analyzing a process & movement of material, men etc.  This is done with the help of all five symbols which represent steps in a chain of steps.  These all symbols are connected to other one by lines and arrows which represent sequence and dependency relationships (i.e., X must be done before Y can be done).
  5. 5. Objectives Of Flow Diagram  The flow charts indicates the sequence of events they do not show the movement of men, material etc but the path of movement can be better visualized by a flow diagram.  Flow diagram is drawn to scale.  It shows the relative position of machines, jigs, fixture, gangway etc and mark the paths followed by men and material.  Distances between two location is indicated in flow diagram.
  6. 6. Steps in drawing a Flow Diagram  Draw to scale the plan of the work area.  Mark the relative position of machine tools, benches, store, racks, inspection tables etc.  From the different observations, draw the actual movement of the material or worker on the diagram.  Indicate the direction of movement.  Mark the distances between consequence two locations.
  7. 7. CHARTS AND DIAGRAMS USED IN METHOD STUDY Following chart are used in method study :(1) OPC - Outline process chart (2) FPC - Flow process chart Man type Material type Equipment type (3) Two handed process chart (4) Multiple activity chart like man and machine chart (5) SIMO chart
  8. 8. The following diagram are also used in method study. (1) Flow diagram (2) String diagram (3) Cycle graph (4) Cronocycle diagram (5) Travel diagram
  9. 9. FLOW PROCESS CHART
  10. 10. FLOW PROCESS CHART  When the overall idea of the process has been established it is possible to go into greater details. Flow process chart can be defined as a graphical presentation of all operations, inspections, delays and storages occurring during a process or procedure which includes information considered necessary for analysis like time required, quantity and distance moved etc.
  11. 11. TYPES OF FLOW PROCESS CHART  Man type -  Material type material. - It records what happens to the  Equipment type - It records how the equipment is used. It records what the worker does.
  12. 12. Flow Process Charts A flow process chart is a chart of all the activities involved in a process. It is similar to an operations process chart, except that more detail is shown by including transportations and delays as well as operations, inspections, and storages. Not usually used for entire assemblies, it is used for just one component (or operator) Add in information on:  Operation duration (time to complete)  Distance traveled (for transport operations) Good for showing savings of a new method.
  13. 13. Flow Process Charts (Cont.) Process charts summarizes the whole process They are used to compare the existing and the proposed methods Process is observed, who, what, where, when, and how questions are asked Every detail is understood and the chart of the existing situation is drawn
  14. 14. 1.Operation Process Chart Symbols Indicates the main steps in a process, method or procedure. Usually the part, material or product concerned is modified or changed during the operation. 2.Inspection Indicates an inspection for quality and / or check for quantity 3.Transport Indicates the movement of workers, materials or equipment from place to place
  15. 15. 4.Temporary Storage or Delay Indicates a delay in the sequence of events : for example, work waiting between consecutive operations, or any object laid aside temporarily without record until required. 5.Permanent Storage Indicates a controlled storage in which material is received into or issued from a store under some form of authorization; or an item is retained for reference purposes. 6.Combined Activities Indicates a controlled storage in which material is received into or issued from a store under some form of authorization; or an item is retained for reference purposes.

  21. 21. EXAMPLES OF FLOW PROCESS CHART
  22. 22. Before and After Comparison Flow Chart
  23. 23. Example Typist has to take dictation from the author’s office. He has to type the letter, copy the letter and get letters attested by the author. He has to prepare the envelope and put these letters in the envelope. Finally place the letter and copy aside the tray. Author’s office is 20 feet away from typist office.

  30. 30. Information shown in a flow process chart :(1) Type of the flow process chart. (2) Information of the person producing the part (3) Information , place ,time & name of operator for whom the product or process is prepared. (4) Different stages and their involved in the process. (5) Transport activity , its various stages and distance travelled in it (6) Different stages of delay ,storage and inspection (7) Summary information of activities
