The tools are:
- Check Sheets – A generic Tool which can be used for collection and analysis of data. A structured and prepared form that can be adapted for wide variety of issues
- Control Charts – This is a graphical technique,which can be used to study the changes to a process over time
- Pareto Chart – This is another graphical technique, which can be used to identify the significance of individual factors
- Scatter Chart – This is used to identify the relation between variables, by plotting pairs of numerical data, with one variable on each axis. The points will be falling on a line or a curve, if the variables are related.
- Cause and Effect Diagram (Also called as Ishikawa Diagram or Fishbone Diagram) – This can be used to structure the brain Storming Sessions. It is used to sort ideas into useful categories. Many Possible Causes are identified for a stated problem and the effect on the problem are identified
- Flow Chart (Stratification Charts) - This tool is used to identify the patterns within the data collected from multiple sources and clubbed together. It is used to identify the meaning of the vast data by identifying patterns.
- Histogram – It looks very much like a bar chart. it is used to identify the frequency of occurrence of a variable in a set of data.
The following presentation introduces the 7 basic quality tools:
Most organizations use quality tools for various purposes related to controlling and assuring quality. Although there are a good number of quality tools specific to certain domains, fields, and practices, some of the quality tools can be used across such domains. These quality tools are quite generic and can be applied to any condition.
The seven basic tools of quality can be used singularly or in tandem to investigate a process and identify areas for improvement, although they do not all necessarily need to be used. If a process is simple enough – or the solution obvious enough – any one may be all that is needed for improvement. They provide a means for doing so based on facts, not just personal knowledge, which of course can be tainted or inaccurate. Ishikawa advocated teaching these seven basic tools to every member of a company as a means to making quality endemic throughout the organization.
