that will be used for this step are stopwatch, pencil and direct observation sheet or blank sheet.
There are few mapping tips given in “Learning to See” book created by Mike Rother and John Shook as follow:
1. Always collect current-state information while walking along the actual pathways of material and information flows yourself.
2. Begin with a quick walk along the entire door-to-door value stream, to get
a sense of the flow and sequence of processes. After the quick walk through, go back and gather information at each process.
3. Begin at the shipping end and work upstream, instead of starting at the
receiving dock and walking downstream. This way you will begin with the processes that are linked most directly to the customer, which should set the
pace for other processes further upstream.
4. Bring your stopwatch and do not rely on standard times or information that you do not personally obtain. Numbers in a file rarely reflect current
reality. File data may reflect times when everything was running well, for example the first-time-this-year three-minute-die-change, or the once-since-
the-plant-opened week when no expediting was necessary. Your ability to envision a future state depends upon personally going to where the action is
and understanding and timing what is happening. Possible exceptions to this rule are data on machine uptime, scraprework rates, and changeover times.

5. Map the whole value stream yourself, even if several people are involved.
Understanding the whole flow is what value-stream mapping is about. If different people map different segments, then no one will understand the
whole.
6. Always draw by hand in pencil. Begin your rough sketch right on the shop
floor as you conduct your current-state analysis, and clean it up later-again by hand and in pencil. Resist the temptation to use a computer.
3. Waste Identification and Reduction
The current state map of the processes revealed some wastes in the value stream selected. Before proceeding to the next step – mapping the future state, it is
important to identify as much waste as it can in the current state map, make some analysis and propose solutions to reduce the influence of wastes.
4. Develop Future-State Map
