The Fundamentals Of
Standard Work
Quick Review
Standard Work Is:
• The best combination of people and equipment,
• Utilizing the minimum amount of labor, space,
inventory, and equipment,
• For a specific level of customer demand
The way we choreograph the operators within a process for a given
level of demand (takt time)

Standard Work
Standardization …
• Reduces Variation
• Enables Flow
• Eliminates Waste
• Fuels Continuous Improvement
... in quest of the:
shortest lead-time
highest quality
lowest cost
Standard Work is part of the foundation

Why Implement Standard Work
• To make it possible to identify and eliminate variations in
operator work
• To sustain the gains achieved from improvement
activities
• To provide a baseline for future improvement
Standard work and variation reduction are key
in creating a foundation of stability.

How Leaders Support Standard Work
•
Ensure that SW is Documented for Each Operator
• Ensure that SW Documentation is Displayed
• Ensure that all operators are trained and follow
agreed upon SW
• Encourage Experimentation and revisions to SW
after improvements are found
• Repeat above cycle

Applying Standard Work
• Team Leaders determine the SW work goal (shared by
work team).
• Everyone seeks to improve against the standard focusing
on identifying and eliminating waste
• Each process in the flow becomes the customer of the
preceding process.
• Each preceding process becomes a just-in-time supplier
for the consuming process (RM towards FG).
• Operational tests, Quality checks, 5S actions, and
material conveyance are included in SW.

Essentials of Standard Work
• Standard Work Is:
• Created by people doing the work, facilitated by their leader.
• Operator Specific
• Specifies content, sequence, timing, and outcome.
• Includes Takt time and Standard Work-in-Process (SWIP)
inventory.
• Clear, visible, and posted at the process.
• Defines the normal condition; normal is not chaotic.
• Only changed based on Takt or improvement by the owners.
Standard Work always enables production.
The standard is the specification for evaluating potential
improvements.
