Seventh Basic tool of Ishikawa’s – Control charts
At Bell Telephone Laboratories in the 1920s, Walter A. Shewhart invented the control chart, also referred to as the Shewhart control chart. It is regarded as a fairly sophisticated quality management tool. This form of graph, which resembles a run chart, indicates the amount and kind of change that a process is experiencing over time. The procedure can be better understood and described by looking at this chart. The utilization of a control chart is crucial as it enables us to monitor and assess a process’s performance in terms of quality. When a process is under “statistical control,” it indicates that there is no quality issue.
Benefits:
- Keep an eye on process stability and look for deviations.
- Differentiate between deviations due to specific causes and common causes.
- Send out early alerts about possible problems.
Limitations:
- Needs to be stable in order to function well.
- Might not pick up on minute changes in the procedure.
- Non-statisticians may find the interpretation to be difficult.
Ishikawa’s 7 Basic tools
In project management, Ishikawa’s has 7 Basic Tools, which also known as the Seven Quality Control Tools. These are foundational techniques used to analyze and improve processes. These seven basic quality control tools, which introduced by Dr. Ishikawa, are
- Check sheets
- Graphs
- Histograms
- Pareto charts
- Cause-and-effect diagrams
- Scatter diagrams
- Control charts
By giving data visual representations and encouraging a common understanding of project difficulties, these technologies not only make problem-solving easier but also encourage collaborative efforts among project teams. Additionally, its incorporation into project management approaches improves deliverable quality overall, expedites procedures, and ultimately boosts project success and efficiency. Thus, for project managers who want to promote continuous improvement and produce high-quality results in their projects, knowing and effectively applying Ishikawa’s seven fundamental tools is a must.
