1-10-100 Rule
The 1-10-100 rule states that as a product or service moves through the production system, the cost of correcting An error multiplies by 10.
Activity Cost
Order entered correctly $ 1
Error detected in billing $ 10
Error detected by customer $ 100
Dissatisfied customer shares the experience with others the costs is
1000 $

Two Types of Approaches ?
1. Control Approach - Shuts down the process when an error occurs. - Keeps the “suspect” part in place when an operation is incomplete.2. Warning Approach - Signals the operator to stop the process and correct the problem.

3 Primary Methods
• Contact
• Counting
• Motion-Sequence
Each method can be used in a control system or a warning system

Contact Method
Missing cylinder;piston fully extended alarm sounds
Contact Method using limit switches identifies missing
cylinder.
Cannot proceed to next step.
Cylinder present
A contact method functions by detecting whether a sensing device makes contact with a part or object within the process.

Counting Method
Used when a fixed number of operations are required within a process, or when a product has a fixed number of parts that are attached to it.
A sensor counts the number of times a part is used or a process is completed and releases the part only when the right count is reached.
![Page 12: Poke Yoke](https://reader037.vdocuments.mx/reader037/viewer/2022102814/54b5a1c94a795927658b459e/html5/thumbnails/12.jpg)

Counting Method : Examples
Another approach is to count the number of parts or components required to complete an operation in advance. If operators finds parts leftover using this method, they will know that something has been omitted from the process.
“I have an extra part. I must have omitted a step!”
![Page 13: Poke Yoke](https://reader037.vdocuments.mx/reader037/viewer/2022102814/54b5a1c94a795927658b459e/html5/thumbnails/13.jpg)

Motion – Sequence Methods
In order to help operators select the right parts for the right step in a process the “sequencing” aspect of the motion-step method is used. This is especially helpful when using multiple parts that are similar in size and shape.
In this example, each step of the machine cycle is wired to an indicator board and a timer. If each cycle of the machine is not performed within the required “time” and “sequence”, the indicator light for that step will be turned on and the machine will stop.
