decide to take a trip for the first time, it is advisable to look at a map. As
you read the map you will realize that you need five very important pieces of
information before you can start your journey:
1. Where are
you starting from?
2. Where is
your final destination?
3. How do
you get from the starting point to your final destination?
4. How much
time do you have to complete the trip?
5. What is
the cost of the journey?
By using a
map you will be able to determine which direction you need to go to get to your
final destination and you can estimate how many miles you need to travel. With
this information you can choose your mode of transport to get you to your
destination within the time available. If you drive you can estimate your total
travel time, number of rest stops and gas usage, etc. I know what your thinking,
"this is all just plain common sense."
would be surprised at the number of organizations who start out on a journey to
create change without first determining "where they are starting from today" and
then planning for "where their final destination is going to be" in order to get
the best results for their business.
If you don't
know where you going any road will do.

mapping (VSM) is a great tool to get you focused on customer needs. VSM will
give a 30,000 feet view of the whole system and from this vantage point you can
identify key areas to improve first in order to give customers what they want,
when they want it. Using a value stream map you will see how the current
activities are performed, how much time each activity is taking and which
activities are "Value Adding" or "Non-value Adding". Customers are only willing
to pay for for value, not waste or non-value activities like, rework, scrap,
Once you identify waste, you see it and then you can try to eliminate
it. However, if you can't see waste then it stays hidden and continues to add
additional costs to the finished products.
three stages to Value stream Mapping:
A Current State Value
Stream Map will show just how you are supplying your customers today. Using
the Current State Map you can clearly see waste and from this determine what
to change and in what order of priority these changes need to occur. The end
result is to identify any process improvements that will allow your company
to supply your customers in more effective manner.
The next stage is to
create a Future State Value Stream Map. This will allow you to eliminate or
reduce waste from the current state process and it shows graphically the
overall effects of these changes on the manufacturing process before you
even move or change anything. Usually the Future State Value Stream Map is a
vision of the manufacturing process over the next 6 - 12 months.
implementation plan using the Future State Map. This implementation plan
will define what to do, when to do it and who is responsible.
If you know
where you are today, it's much easier to know where you want to be tomorrow, and
you can plan to make the transition into the future state a much easier,
enjoyable and successful event.
