Activity #1
• Dice moves clockwise
• Chips move counter clock wise
• If you have no chips, skip your
role and pass the dice
• The amount on the dice
equals the number of chips
you pass to your right
• Record on your sheet your
progress with each role

Why Reduce?
Variation can lead to a number of different effects:

How?
So what can we do… ?
• Communicate milestones
visually
• Break larger sequences of
work into consistent hand offs
• Review and DOCUMENT
successes and failures
• Standardize where ever
possible

How?
So what can we do… ?
This is where you "Measure
twice, cut once“
And set goals and make
them visual
This is where you complete
consistent handoffs of work
This is where you review and
document best practices and
lessons learned
This is where you standardize

Activity #2
Standardizing Your Work – Pig Exercise
Gilbane Building Company | September 2018 14Confidential and proprietary information.
Activity #2
Standard Work
A set method that uses the best combination of people, materials and equipment for
conducting work processes safely at consistently high quality and the lowest possible
cost
• It is the best-yet-identified, least-waste way of conducting the work.
• It is an excellent communication and understanding tool.
• It allows employees & supervisors to improve.
• Typically includes explicit: Content; Sequence; Timing; Output

Activity #2
Everyone needs a piece of paper
A drawing instrument (pen, pencil, etc.)
Put your name on the paper
You have 90 seconds
NOW – Draw a pig!
Let’s Conduct A Standard Work Exercise
Gilbane Building Company | September 2018 16Confidential and proprietary information.
Activity #2
What does the customer think of the pigs?
Do they meet customer needs?
Was the process > Effective (good, consistent quality)?
> Efficient?
> Flexible?
> Stable?
> Controllable?
> If you all worked on one piece of the pig would things have fit together?
How did you feel about your work?> Could it be improved?
> How?
Let’s try with “standard work”. You will all have standard “paper” and standard “instructions/procedures”.

1. Draw a letter M at the top left intersection. Bottom center of M touches intersection.
2. Draw a letter W at the bottom left intersection. Top center of W touches intersection.
3. Draw a letter W at the bottom right intersection. Top center of W touches intersection.
4. Draw an arc from the letter M to the top right intersection.
5. Draw another arc from the top right intersection to the bottom right W.
6. Draw an arc between the two bottom W’s.
7. Draw the letter O in the center left box.
8. Draw an arc from the letter M to the tangent of the circle.
9. Draw an arc from the left W to the tangent of the circle.
10. Draw an arc for the eye. Half way between M and circle.
11. Draw an arc for the mouth. Half way between W and circle. Must be a happy pig!!
12. Draw the cursive letter e near the top of arc on the right.
13. And finally draw two dots in the middle of the circle for the pigs nose.

What does standard work give us?
• A foundation for improvement
• A way to understand capacity
• A way to know when problems are occurring
• A way to reduce variation
• A way to see waste
• A way to build-in quality, safety, productivity
• A way to share learning – everyone understands the “tribal
knowledge”
• A way for employees to create the best way to work

Defining Success
What do we want… results that are repeatable!

Wrap up
The challenge…
• Create space in your project
planning for including goal
setting and visualization of
success
• Do not consider a project
complete until you and your
team have done a deep dive
on successes and failures
• Brainstorm with your team on
what and how you can
standardize work
