out of
the process

3 Types of Interruptions
• Abnormalities
• Process Design Interruptions
• Product Design Differences
7
Abnormalities
• Machine
• Material
• Training
• Feedback
8
Process Design Interruptions
• Non-cyclical tasks designed into the process that interrupt the cyclical work
9
Product Design Differences
• Customer wants variety, choices• Minimize impact to the operator’s
work flow
10
What is Standardized Work?
• An agreed upon set of tasks • resulting in the best sequence
of human motion and machine • achieving the best quality output in the
safest manner with the least labor, space, inventory and equipment
• that is continually improved

Process Variation is the Enemy!

Standardized Work not
only a concept but also
a means to identify,

Never be satisfied
“Any improvement must be made in accordance with the scientific method, under the guidance of a teacher, at the lowest possible level in the organization.”
Steven Spear & H. Kent Bowen

• Stating a hypothesis
• Test the hypothesis
• Confirm or disprove hypothesis

Method of Implementation

Three options:• Adjust &
experiment again• Adopt the change• Abandon the idea
• Experiment – test the change
• Develop idea• Determine expected
result
• Monitor & Measure• Analyze gaps between
actual & expected
• Identify the problem• Define current situation• Analyze potential causes

Tools of Continuous Improvement
• Continuous Improvement Board
• Focus Board
• Story Board
21
22
Continuous Improvement Board
• Purpose: Employee involvement in process improvement. Captures quick and easy ideas that can be implemented by the employees.
• Process: Use of a card on the Board that follows PDCA methodology and visually shows the progress of the idea.
23
Focus Board
24
Focus Board
• Purpose: Focus on a specific issue that may involve multiple stations.
• Process: Team problem solving approach. Grasp the situation through run charting and Pareto analysis. Test several hypotheses and look at the impact.
25
Story Board
26
Story Board
• Purpose: Problem solving requiring deep root cause analysis. Used by team members supporting the value stream (engineers and leaders.)
• Process: The employee uses a standard template to present the problem solving process from problem description, through the 5 Why analysis, to permanent counter measure.
