2. Flow Process Chart A Flow Process Chat is a symbolic representation that illustrates the sequence of activities within a process. It is used to record and analyze the activities that make up a process to determine which add value and which do not. Activities can be any operation, inspection, storage, transportation, and delay actions that are carried out by an individual person, a team, a machine, a computer system, or a combinations of all.

3. Flow Process Chart Cont…. There are three common types of flow process charts based on what is being charted. A man-type chart shows the activities of a person or group of people, a material-type chart shows what happens to a product or item as it moves, and an equipment-type chart shows the activities from the viewpoint of the machine or equipment involved. Activities are often recorded along a vertical or horizontal line using common symbols and descriptive words. These symbols have been accepted by many Lean practitioners and organizations. Other symbols can be used based on the situation.

4. Flow Process Chart Examples The following are the explanation of each of the five categories, along with examples listed with them: OPERATION: Produce, add, change, or process something. Examples: Drilling a hole in metal – Serving a customer at a call center. INSPECTION: Checking of items to ensure correct quality and/or quantity. Examples: Checking for defects – Measuring the dimensions of a product – Counting received products – Getting feedback from a customer. STORAGE: The storing of something until later time. Examples: Storing of finished goods in a warehouse – Storing of supplies received in a storeroom as inventory.

5. Flow Process Chart Examples cont…. DELAY: The temporary waiting of something or somebody. Examples: The time spent waiting for maintenance and repair activities – The time the customer spent waiting in a queue. TRANSPORT: The movement of people, materials, or other items between locations. Examples: A forklift moving pallets from a warehouse into a loading bay – A customer walking from sales floor to cashier. Other symbols can be used based on the situation.

6. Parts of a Flow Process Chart A particularly useful feature of the chart is that it can be drawn up as the process is happening. Thus you can follow a part around a factory floor, for example, noting how and when it is machined, stored, moved, etc. The table below shows many of the symbols that may be found in Flow Process Charts.

7. How it works The Flow process Chart is a simple half-text, half-picture method of showing the steps in a process, using symbols to indicate the type of action being taken and text to give details of the action. The chart can selectively be used to show what happens to selected people, materials or equipment. Symbols indicates types of action Text description give detail of action Get invoice from document drawer Complete invoice of goods Take completed invoice to account dept Wait for transcription and printout Sign for completion of work Take final invoice to post room

8. How it works cont… Identify the process to be charted and the objective for charting it. Identify the symbol set to be used. Record the steps of the process as it happens, starting at the top of the page, with symbols on the left overlaying a vertical line with appropriate notes about what is happening to the right. Try to record significant activities which are generally of approximately equal size (unless the problem is at the detail level, do not try to capture too much detail). We can also make the diagram more useful by such tricks as numbering the different action types in sequence (for example so you can see how many times the item under examination was moved) and changing the direction of movement arrows to show input or output activity. You can also put the time taken in each activity to the left of the symbol.

9. How it works cont… If we are watching the process as it happens, we may want to repeat the analysis several times to ensure that we have captured the normal chain of events. Analyzing the final chart, for example the total times taken in non-value-adding activities such as storage, movement and inspection. Using the Flow Process Chart

10. Example The following example shows a flow process chart and a process chart for processing an invoice after received by the supplier. The process begins after receiving the invoice and ends with paying the supplier. The following table is the process chart summary, which is useful to estimate key performance metrics.

11. Two-handed Process Chart (or) Right Hand, Left Hand Chart It is the process chart in which the activities of two hands of the operator are recorded. Motions of both hands of worker are Right hand-Left hand chart recorded independently. It shows whether the two hands of the operator are idle or moving in relation to one another, in a timescale. It is generally used for repetitive operations.

12. Two-handed Process Chart cont… The objective of this investigation is to eliminate or reduce the unwanted motions and to arrange the remaining motions in a best sequence. A two-handed process chart is made up of two columns in which the activities of the left hand and right hand and the appropriate symbols are respectively recorded in sequence. The activities of the two hands are inter-related by aligning the symbols on the chart so that movements by both hands appear opposite to each other. Additional columns can be designed to record the activities of the other parts of the body whenever necessary.

13. Two-handed Process Chart cont… Operation: An operation occurs when the hand grasps, releases or assembles tool, material, component etc. Transport: Transport occurs when the hand moves from one position to another at the work place. Delay: Delay occurs when the hand is Idle in the sense that it is not performing any activity. Hold The term storage is not used in connection with the two handed process chart. Instead the symbol is re designated as hold. A hold occurs when the hand holds an object so that the other hand may be able to do something to that object. Inspection This symbol is not generally used in this
