Every issue has different characteristics and different quality tools will be appropriate to gather and analyse data. Teams of people who can apply elements of these seven tools will find that their ability to solve problems is greatly enhanced and they can quickly move from opinions to facts. RCA Rt has a special training course that covers 7 Quality Tools in addition to 5WHYS and 12 STEPS + CauseTree.
1. Ishikawa or fishbone diagram.
Also called fishbone diagrams or herringbone diagrams. Diagrams are created by Kaoru Ishikawa, that graphically show potential causes of a specific event. Commonly used in brainstorming.
2. Check Sheet.
Normally a form that is structured in a way that assists in gathering data or executing a procedure. Simple counting required.
3. Control Chart.
A graph that is used to illustrate how something changes over a time period. They are used to determine if a manufacturing or business process is in a state of statistical control.
A common graph used to show how often various things happen in a set of data (sometimes called frequency distributions).
5. Pareto Chart.
A bar graph arranged to show the most important issues. It helps identifying the 80:20 rule in Pareto's principle, which says that 20% of causes (vital or significant few) are responsible for 80% of effects.
6. Scatter Diagram.
Graphs pairs of data with one variable on each axis. Excellent for searching for patterns and comparisons.
7. Stratification, Flow Chart and Run Chart.
Stratification seeks to find a hidden variable in a dataset. Run Charts plot the changes in a variable over time. Flow charts are a representation of a process.
Visual devices help visually communicate the priorities during the investigation. They are specially designed by us, and are unique in the entire problem solving industry. Our Visual Devices help you in all problem solving investigations, regardless if you use the RCA Rt our method or not.
