Catapult Exercise
• You have been pre-selected (based on your skills and past performance records) for the openings posted for Her Majesty’s Catapult Squad.
• Problem Statement: Catapult launching is not capable of meeting Her Majesty’s requirements over the target range of 5-12 feet +/- 6 inches.
• Goal: Your mission is to optimize the inputs to be able to hit a target repeatedly within this range so that Her Majesty can conquer the evil Empire.
• A successful catapult squad can place a payload to the target every time. (Only 3.4 misses per million!)
• The distance from the target varies due to several factors; consequently, you don’t know the distance until you’re in position.
• May the FORCE be with You!! Heads rolled on the last crew which is why we have postings for the current positions!

This is the middle of the funnel for most projects (multiple X’s or with variable relationships between X’s)– for some simpler projects with a single X, this is the
bottom of the funnel, the final vital X
Important X’s for Y = f(X1, X2, …, Xn) – we still need to determine “f”

Step 8: Discover Variable Step 8: Discover Variable RelationshipsRelationships
How the X’s affect Y Evaluate how my Vital X’s affect Y, either independently
or in combination with other Vital X’s. This is primarily done through the use of DOE or Regression.
This is the bottom of the funnel, I know which X’s affect my Y and I know how they affect Y
The function Y = f(X1, X2,…, Xn) is called a “transfer function” – it describes how a change in one or more of the X’s transfers to a change in Y
We now know what Y = f(X1, X2, …, Xn) is
The variable relationships within many Green Belt projects are frequently established simply through the use of standard hypothesis tests.
Step 9: Establish Operating Step 9: Establish Operating TolerancesTolerances
How To Set My Xs I know which X’s are important. What settings do I use to
improve my project? In the case of a variable X (e.g. PSI on an air feed), I have
to provide a setting tolerance (e.g. a target amount ± an allowed amount of variation about the target)
In the case of a non-variable X (e.g. Supplier), I know which value of the variable provides the best value of Y, therefore I have specified the absolute operating tolerance
Make use of what we know about Y = f(X1, X2, …, Xn)
In our case study we will “set the X’s” at the settings of our improved process.
Improve PhaseImprove Phase
We will conduct a 2k factorial experiment in order to identify the proper factors and levels to achieve the highest capability (Zst). – You only have enough resources to investigate three
X’s at 2 levels – Determine your factors and their respective levels. – Use the knowledge you learned in DMA and as a team
determine what factors and the respective levels you want to use to conduct the DOE

There are 4 possible combinations to hit the target. Which one minimizes variation?
Recommended Pin Factor Level SettingsRecommended Pin Factor Level Settings Stop Pin: 2 Front Tension Pin: 2 Recall the equation for AvrgD:
– AvrgD = -378.7 + 70.03 * StopPin + 2.39 * DrawAngle + 15.04 * TensionPin - 0.42 * StopPin*DrawAngle
Enter the fixed settings into the equation for AvrgD:– AvrgD = -378.7 + (70.03 * 2) + 2.39 * DrawAngle + (15.04 *
2) - 0.42 * (2*DrawAngle) Reduce the equation:
– AvrgD = -378.7 + 140.06 + 2.39 * DrawAngle + 30.08 - 0.84 * DrawAngle
– AvrgD = -208.6 + 1.55*DrawAngle Substitute the target (60”) for AvrgD and solve for Draw Angle
– DrawAngle = 173.3 degrees

Step 10: Validate Measuring Step 10: Validate Measuring SystemSystem
Can I Measure My Xs & Y? In the case of a variable X (e.g. PSI on an air feed), I need
to validate that it can be measured (a vital X MSA) In the case of a non-variable X, I need to validate that I can
tell whether the X is the right value (e.g. is this from Supplier A?)
Also, I might have improved my Y so much that I can no longer “read” my process, and may have to improve my measurement system to truly measure the improvement
Can’t control Y = f(X1, X2, …, Xn) if you can’t measure it

Common tools:– Six Sigma Capability Analysis (Normal) for continuous
data– Six Sigma “Product Report” for discrete data
Can you consistently make X1, X2, …, Xn to produce “good” Y’s?

Step 12: Implement Process Step 12: Implement Process ControlsControls
Let’s Not Do This Again The X’s you have determined as vital, their settings, and
other actions you have taken to make the improvement must be:– nailed down– set in concrete– fully implemented (NOT just agreed to)– put into a rigorous audit schedule– Documented in a Control Plan
BEFORE you can say a project is closed!
How do you control X1, X2, …, Xn to always produce “good” Y’s?
Controls – Two RequirementsControls – Two Requirements1) The actual controls Controls must be placed on completed projects to make sure that they do
not decay – Energy must be expended on processes to keep them in their optimum condition.– The degree of control is proportional to the risk of the process
decaying from its final project derived settings.2) The Control Plan The controls must be documented carefully, answering:
– What is being done?– Who is to do it (position not name of person)?– When is to be done?– What will be action if process does decay?– What will make it difficult to change the project settings OR controls?

A catapult team decided that they needed to be able to control the Draw Back Angle.
An observer requested an operator to launch consecutive balls at an angle of 180 degrees.
The observer, through special visual imaging equipment, recorded the angle and the distance of each launch.
Is the operator able to control the angle? Generate a control chart and flip chart your

Catapult Control Plan ExerciseCatapult Control Plan ExercisePurpose: To develop a Control Plan that sustains the gains of the work our Six Sigma Team performed that optimizes the capability of the catapult to deliver conforming product.
You and your Six Sigma team have have successfully completed a project by identifying the critical X’s and their respective levels in order to achieve your project objective. It is now time to hand the project over to the Process Owner, therefore a Control Plan needs to be developed. This Control Plan needs to contain the proper information that will allow the Process Owner to sustain the gains your team has achieved.
Any six sigma project must have a control plan

which she described the test as follows: “The winning design will be the one that is able to launch ammunition into
a fine goblet from various distances.” Further, the marketing team overheard that Her Majesty herself would fire
the catapult after a short tutorial from the gunsmith.
After you have completed the control plan and documented your SOP’s, I will give you a new target to hit. You will have 5 minutes and 3 launches (within those 5 minutes) to identify a new set of operating conditions. You will set up the catapult at these new conditions. I will read your Standard Operating Procedures and then launch 10 balls. The capability of these launches will be included in the final competition calculations.
