Value Stream Mapping and Lean Manufacturing

Esteem stream mapping is a ‘lean assembling’ framework used to comprehend the stream of data and items to the client. The framework started in the Toyota plant where it was named as ‘material and data stream mapping’. This wording is utilized as a part of the procedure/forms that need change.
This is a useful technique that can be utilized as a part of a ‘lean’ situation to enhance the ‘lead time’. This framework is valuable in the assembling procedure as well as in coordinations, benefit related ventures, human services and item improvement. It is a perception device arranged to the TPS. It helps in comprehension and streamlining work forms utilizing the different ‘apparatuses’ and ‘methods’ of ‘lean administration’. The objective of Visual Stream Mapping is to recognize and show squander in the framework, and take out the same. This framework is taken as a beginning stage for the makers, generation engineers, providers, schedulers, relates and even clients to distinguish and dispense with squander in any shape. In this way, it can be seen that the visual mapping stream isn’t just a specialized instrument yet additionally a key arranging device and a change administration apparatus.
Keeping in mind the end goal to accomplish this end, the visual stream mapping framework maps the stream of materials from the time they enter the industrial facility premises, through the generation line and straight up to the time they touch base at the dock for shipment as completed items. Mapping out the different exercises in the assembling procedure (down circumstances, process durations, in-process stock, and material moves and so forth.) pictures the present condition of the procedure exercises, and aides that state to a future wanted state. The methodology by and large incorporates the ‘physical’ mapping of the present state while likewise concentrating on the ‘future’ state. This, at a later stage, would fill in as the venturing stone for future ‘lean’ administration methodologies.
In the Toyota Production System (TPS) seven squanders were recognized. These squanders were usually acknowledged. They are:-
Unseemly preparing
Transport(inordinate delay)
Superfluous inventory(excess stock)
Overproduction(faster than would normally be appropriate pace)
Defects(correction of errors)
Superfluous movement
Unseemly preparing
Having recognized the seven innate squanders, the seven Value Stream Mapping instruments are as under:-
Process action mapping
Inventory network reaction
Generation assortment channel
Physical structure mapping
Choice point examination
Request enhancement mapping
Quality channel mapping
There are four stages to Value Stream Mapping:-
a) Define and pick the item and, or the item family.
b) Create the present state Value Stream Mapping.
c) Create the Future state Value Stream Mapping.
d) Develop an activity intend to make the FSVSM and the CSVSM.
