Seven tools of quality
The seven basic tools of quality ( Engl. Seven Tools of Quality , and Q7 ) are a collection of methods of quality assurance , for the first time by Kaoru Ishikawa compiled around 1943.
A number of quantitative methods and instruments are used to identify problems and their possible solutions for continuous improvement in areas such as manufacturing. Most quality problems can be resolved through the use of seven basic quantitative tools known as the traditional "seven tools of quality". These are:
- Ishikawa diagram
- Pareto diagram
- Check Sheet (Engl. Check sheet )
- Quality control card (QRK) or control card for short
- Program schedule (PAP, flowchart )
- histogram
- Scatterplot (Engl. Scatterplot )
All in all, these tools are suitable for separating opinions from facts and then analyzing these facts. The results of this analysis include an interpretation and, if possible, the introduction of measures to eliminate the problem. The Q7s are widespread and are used by quality departments in most organizations. A number of extensions and improvements were proposed and adopted. There are also the " Seven Management and Planning Tools ".
