Is it possible to resolve 95% of quality issues in a factory using just a handful of (digital) tools?

Referred to as the seven basic quality tools, or 7QC/7QTs, this set of graphical and statistical instruments can effectively and efficiently analyze and address workplace challenges. According to Kaoru Ishikawa, the Japanese expert who pioneered the quality circle movement and introduced the fishbone diagram, around 95% of quality issues can be tackled if management focuses on the insights and outcomes derived from these seven tools:

1. Check sheets

These are straightforward tools for recording data, whether it's statistical or observational, typically formatted as a table where users can mark off items like a checklist or scorecard.

2. Fishbone diagram (cause and effect)

This brainstorming method illustrates how one action can influence another, helping to identify potential causes of problems.

3. Histogram

A popular choice in six-sigma practices, this bar chart displays data over specific time periods, aiding in forecasting and problem-solving.

4. Pareto chart

This visual tool highlights the 80/20 principle, showing that 80% of issues often stem from just 20% of causes, making it a valuable problem-solving resource.

5. Control chart

Monitoring variations and anomalies is crucial for any organization. This graph offers a robust way to interpret real-time data.

6. Scatter diagram

This simple plotting tool illustrates the relationship between two numerical variables, helping to identify trends and discrepancies.

7. Stratification (flow chart)

This method categorizes data into similar groups or strata, making it easier to analyze information from various sources, such as different suppliers or shifts.

Although these seven basic quality tools were introduced by Ishikawa long ago, they remain relevant and effective in today’s modern manufacturing environments.
