Poke Yoke (Mistake proofing): Also called: poka-yoke, fail-safing. Mistake proofing, or its Japanese equivalent poka-yoke (pronounced PO-ka yo-KAY), is the use of any automatic device or method that either makes it impossible for an error to occur or makes the error immediately obvious once it has occurred. It is a common process analysis tool.

Benefits of poka-yoke implementation
Less time spent on training workers
Elimination of many operations related to quality control

7 QC Tool
The 7QC tools are comprised of simple graphical and statistical techniques which are helpful in solving critical quality related issues. At Awwa we adopt 7QC tools since it could be implemented by any person with very basic training to solve complex quality issues.

1. Cause-and-effect diagram (Ishikawa or fishbone diagrams): Identifies many possible causes for an effect or problem and sorts ideas into useful categories.
2. Check sheet: A structured, prepared form for collecting and analyzing data; a generic tool that can be adapted for a wide variety of purposes.
3. Control chart: Graph used to study how a process changes over time. Comparing current data to historical control limits leads to conclusions about whether the process variation is consistent (in control) or is unpredictable (out of control, affected by special causes of variation).
4. Histogram: The most commonly used graph for showing frequency distributions, or how often each different value in a set of data occurs.
5. Pareto chart: A bar graph that shows which factors are more significant.
6. Scatter diagram: Graphs pairs of numerical data, one variable on each axis, to look for a relationship.
7. Stratification: A technique that separates data gathered from a variety of sources so that patterns can be seen.
