The document discusses various quality control (QC) tools essential for maintaining product quality and operational efficiency, including flowcharts, Pareto charts, cause-and-effect diagrams, check sheets, control charts, histograms, and scatter diagrams. These tools facilitate data collection, analysis, and identification of issues, ultimately supporting continuous improvement and standardized processes within organizations. By leveraging these QC tools, businesses can make informed decisions that promote sustainable growth and quality excellence.

2. Introduction
to Quality
Control

3. Quality Control
→ Quality Control refers to the processes and techniques used to
ensure that products or services meet specific quality standards.
→ QC is crucial for maintaining consistency, meeting customer
expectations, and improving overall operational efficiency.

4. What are QC Tools?
The QC tools are basic tools which help in
resolving business issues through:
•Data collection & analysis
•Root cause identification
•Identify solution through data stratification
•Controlling the improved state

5. “As much as 95% of quality
problems can be solved with
seven fundamental tools.”
- Kaoru Ishikawa

6. Flow Chart

7. Flowchart
→ A Flowchart is a diagram that represents a process, showing the
steps and decision points.
→ To find the bottlenecks and unnecessary steps within the system
or process.
→ Quality-checking tool used to document process flow and
organizational structures.

8. Steps For Creating An Effective Flowchart
Identify the
process
Define the
steps
Incorporate

10. "If you can’t describe what
you’re doing as a process,
you don’t know
what you’re doing!"
-W.Edwards Deming

Data Analysis
Useful for analyzing
the frequency and
impact of defects or
issues within a
process or system.

15. Pareto Chart
→It is a technique for identifying the most significant
factors contributing to a problem or issue.
→Example: Identifying the most common types of
defects in a manufacturing process.

18. Cause-and-
Effect Diagram

19. Cause-and-Effect Diagram
It is a visual representation used to
identify and explore the potential causes
of a specific problem.
Example: Using a Fishbone
Diagram to analyze the causes of
equipment downtime in a
production line.

20. Steps to create a Cause-and-Effect Diagram

22. Check Sheets

23. Check Sheets
It is simple data collection tools used to gather and
organize data in a systematic way.
It's a simple and effective tool for data collection
and analysis, often used for quality control
purposes.
Example: Using a check sheet to track defects on
a production line.

24. Tips for creating effective check sheets
Ensure Ensure Ease Of Use
Provide Provide Clear Instructions
Define Clearly Define Categories

26. Control Charts

27. Control Charts
→ Control Charts are graphical tools used to monitor the stability and
consistency of a process over time.
→ Monitors and displays the variation in a process over time.
→ Aiding in maintaining process stability.
→ Example: Tracking the variation in the diameter of manufactured parts over
multiple production runs.

30. Histograms

31. Histograms
Histograms are visual representations of the
distribution of data.
Displays the distribution of data, allowing
analysis of variation and identification of
patterns.
It graphs the frequency of occurrence of
continuous data.

33. Scatter Diagram

34. Scatter Diagrams
Scatter Diagrams
are used to
identify
relationships
between two
variables.
Graph uses dots to
display the values
of two variables.
Analyzing the
correlation
between the
variables.

36. Conclusion
Continuous Improvement
• Utilizing these tools supports a culture of continuous
improvement and sustains quality excellence.
Optimized Decision Making
• Empowers organizations to make data-driven, informed
decisions, leading to sustainable business growth.
Standardized Processes
• The use of the QC tools helps establish standardized processes,
ensuring consistency and reducing variability in operations.
