Overview
SIST ISO 11462-2:2014 - Guidelines for implementation of statistical process control (SPC) - Part 2: Catalogue of tools and techniques - outlines a comprehensive catalogue of tools and techniques to support organizations in planning, implementing, and evaluating an effective Statistical Process Control (SPC) system. Published by SIST and based on ISO 11462-2:2010, this standard serves as a practical guide to enhance quality management through structured statistical methods, helping organizations achieve reliable process performance and continual improvement.
By referencing widely recognized statistical control methods and providing practical guidance, SIST ISO 11462-2:2014 enables organizations to systematically address process variability and maintain consistent product quality.
Key Topics
-
Catalogue of SPC Tools and Techniques: The standard provides a structured list of essential tools and techniques, categorized for ease of application in different phases of quality management.
-
Purpose and Application: Guidance on using the catalogue in quality planning, process control, and continual improvement initiatives.
-
Classification and Selection: Systematic classification enables organizations to choose suitable tools for specific process challenges.
-
Recommended Tools and Techniques:
- Control charts (p, np, c, u, X-bar and R, X-bar and s, EWMA, CUSUM)
- Pareto analysis and cause-and-effect diagrams (Ishikawa/fishbone)
- Process capability indices (Cp, Cpk, Pp, Ppk)
- Histogram, scatter diagram, stratification, check sheets, sampling, and regression analysis
- Root cause tools (FMEA, FMECA, Fault Tree Analysis)
- Relational and quality planning tools (Affinity diagrams, Quality Function Deployment, Process flow diagrams)
- Measurement system analysis (repeatability & reproducibility)
-
Continual Improvement: Integration of SPC tools into ongoing quality and process improvement initiatives.
Applications
SIST ISO 11462-2:2014 is valuable for diverse organizational contexts aiming to improve process performance and product quality through SPC. Typical applications include:
- Manufacturing and Process Industries: Identification and control of process variation to minimize defects and optimize production efficiency.
- Service Organizations: Reducing errors, analyzing customer feedback, and improving service delivery through data-driven decision-making.
- Quality Management Systems: Implementing SPC as part of ISO 9001 or other quality management frameworks to demonstrate control and capability.
- Continuous Improvement Programs: Supporting Six Sigma, Lean, and other operational excellence initiatives with standardized quality tools.
- Training and Competence Development: Providing a baseline toolkit for quality professionals, aiding in the training and upskilling of staff in SPC methodologies.
Related Standards
SIST ISO 11462-2:2014 builds on and references several foundational international standards, offering compatibility and guidance for integration:
- ISO 11462-1: Elements of SPC - foundational elements related to statistical process control systems.
- ISO 7870 Series: Control charts, including guidelines and specialty applications.
