A VSM Standard for a Lean deployment
What Is a VSM Standard ?
A Value Stream Mapping standard applies the lean concept of standard work to the activity of creating
and leveraging value stream maps. These are critical assets at the heart of a lean deployment. As with
other standard work this is a documented method such that the work can be easily done according to the
standard. Because there is a standard, it can be improved over time and any improvement leveraged
over the whole organization.
eVSM has been designed to promote the creation and leverage of a VSM standard. This document
discusses how this is done and provides metrics on the benefits
Who uses the VSM Standard ?

Practitioner
The standard is used by everyone involved in
drawing, analyzing and comprehending value
stream maps. It’s highly leveraged in any
Process
organization involved in a lean deployment.

For critical parameters on the map, standard

What are the benefits ?
The benefits of a standard are :
1. Rapid mapping
2. Eliminating need to write basic equations
3. Eliminating need to define basic charts
4. Easier and uniform map comprehension
5. Less errors

Equation – Equations allow some variables (like
NVA Time or Production Lead Time) to be
automatically calculated from other data on the
map. Equations are processed using Excel and can
use any excel functions.
Managed Equations in eVSM are part of the VSM
Standard.
Takt Time (Secs) = Demand / Production Time (Secs)
Set – A combination of names, units and
equations can be stored and distributed to other
Units
users as a “set”. A “set” and “stencil” (see below)
together define a VSM Standard.

Stencil – Macro Shapes can be moved to a
stencil from which they can be applied with a
drag & drop. This stencil can be saved as a file
to use on new maps or share with others.
A “stencil” in combination with a “set” comprise
the VSM Standard in eVSM.
A VSM Standard button on the computer
desktop automatically opens eVSM with the
standard for new maps.

Steps to Create a VSM Standard
Basic Steps
Follow these steps to create a VSM standard:
Decide on Names & Units you would like to use
and enter these into the eVSM as a Set.
Write Managed Equations.
Create macro shapes.
Put the macro shapes in a stencil file.
Getting Help
Contact us to help you create a standard. It’s not
difficult and really pays off. We will be hosting
webcasts that illustrate standards development and
usage corresponding to some of the key workbooks
in our lean library (such as “Learning To See”).

Eliminating Waste
Mapping without a VSM standard will result in a great deal of waste !. eVSM is explicitly designed to help you
create and leverage a VSM standard to the benefit of your organization. Contact us to see how.
