VSM — Value Stream Mapping

In plain English

Value Stream Mapping is a method used to visualize and analyze a value stream to identify waste and improvement opportunities.

VSM is how you draw the value stream.

It turns a messy reality into a shared picture — showing:

steps

delays

handoffs

and waiting time

Seeing it on one page is usually uncomfortable.

What they actually mean

VSM doesn’t create improvement.
It removes denial.

Once the map is visible, the excuses disappear:

“I didn’t know”

“That’s not my part”

“It’s always been like this”

If the map looks bad, the system is bad — not the people.

Example

Does it actually matter?

Yes — diagnostically.
VSM helps teams agree on what’s actually happening.

Improvement gets easier once everyone is looking at the same problem.
