Process Mapping is "the process of putting on a map, using specialized symbols, the process that you what to talk about".

Process Flow Chart is one of the many tools you can use to map your process.

Different diagramming tools that you can use to map your process.
You have to use the right one according to your purpose for mapping the process.

Charts developed in industrial engineering


Operation Process Chart
Flow Process Chart
Operator Process Chart


Charts that were subsequently developed in other disciplines and techniques.

Value Stream Mapping


I want to portray value stream mapping as process wide diagram of delays in flows. It means the temporary delays shown in the flow process charts of various parts, sub-assembly and assembly are visualized in more detail in value stream map. In flow process charts or operation process charts, I want to bring in the data block used in VSMs in a data column. Presently there is remarks column in the process charts. We need to add data column. The flow process chart clearly tells industrial engineers to learn more about production processes, inspection processes, material handling processes and warehousing processes. I would say none is covered in my NITIE syllabus when I studied. Today also in industrial engineering curriculums, there is no adequate content in these areas. That is how we give degrees to weak IEs who do imaginary engineering - that is zero engineering.

Value stream mapping vs. process mapping to drive process innovation

What's the difference between value stream mapping vs. process mapping? One is focused on making an existing process more efficient, while the other dissects the value of each step

The Origin of Value Stream Mapping
 “Material and information flows” chart is a technique of visual mapping the Toyota Motor Corporation used to understand the material and information flow within the organization.

The term ‘value stream’ was first coined by James Womack, Daniel Jones and Daniel Roos in their book, The Machine that Changed the World in 1990. It was further popularized in Lean Thinking by James Womack and Daniel Jones in 1996. 
In Learning to See (1998) Mike Rother and John Shook explained in detail the application of the method in manufacturing. Then in 2004, Beau Keyte and Drew Locher discussed the extended application of value stream mapping in office and administrative processes.

What is Value Stream Mapping?
A value stream map, t helps identify non-value adding steps that should be eliminated and areas in the process that should be improved to achieve better and faster outcomes.

A value stream map can be divided into 3 segments,

Production or process flow
In this section,  the flow of the process is drawn from left to right. 

Information or communication flow
In this section (at the top portion of the map) all the communication, both formal and informal, that occurs within the value stream is shown.  

Timelines and travel distances
Timelines appear at the bottom of the value stream map.  While the top line indicates the invetory  time, the bottom line indicates the cycle time. Another line, placed at the bottom of the map shows the travel distance (of the product or work or of the people moving) through the process.

Can somebody tell me the difference between the flow chart - process mapping - value stream mapping?

Answers

1
These are the typical differences, but some may use them interchangeably:
Flow chart - typically a basic, unadorned graphical representation of the process using boxes as process steps and connecting arrows
Process Mapping - starts with a flow chart, and typically adds detail such as inputs and outputs of each process step (used in Six Sigma)
Value Stream Mapping - Starts with a flow chart and adds time for each process step as well as the delay between process steps, including transportation. Also identifies each step as Value-add or Non-value-add (used in Lean)

2
Value-Stream Mapping is both material and information flow. So, not only does it show process flow (usually horizontally, not vertically as in a flow chart), but it includes data associated with each process, inventory between processes, the method by which material moves from one process to another, and information flows between and among Production Control, the processes, suppliers, and customer. It also includes (most importantly) customer demand.

Further more.........

a flow chart tends to represent the 'logic' behind the process, as in the original application of flow charts, which is computer programming. It assumes 100% yield from the process which is 'logical'.:yes:

A process map, if done effectively, will show the actual process, including non-value added steps, and can be used to identify the waste in a process. For example, process mapping the purchasing process might show that 50 requisitions are handled (per week) but 10% do not complete the process due to a lack of information. These can 'sit' in the process (on a buyers desk) so the 'yield' from the requisition process isn't 100%. That 10% still need to be completed, so the next week, the volume goes up to 55. During each subsequent week, the volume increases, until at the end of the month, the buyer has to work overtime to clear outstanding incomplete requisitions. In the meantime, the people who wanted the buyers to pace an order are still waiting for their delivery!! This issues wouldn't necessarily be revealed by a flow chart.....:nope:

It can be used to identify increased costs such as overtime when 'standardized work' isn't being done.

A value stream map can do the same, but for 'product' rather than 'data'

The Strategos Guide to Value Stream & Process Mapping

Quarterman Lee, Brad Snyder
Enna Products Corporation, 2007 - Business & Economics - 159 pages

At last, this much anticipated book has been published and provides a much needed breath of fresh air. The Strategos Guide to Value Stream and Process Mapping has helpful tips on facilitating group VSM exercises and helps put VSM in the greater Lean context. With photos and examples of related Lean practices, the book focuses on implementing VSM, not just on drawing diagrams and graphs. This is the most comprehensive and practical book on the subject to date.
