Exhaustive Guide to Quality and Environmental Management Systems (ISO 9000 and 14000)

Quality Management Systems: Overview and Foundations

• The International Organization for Standardization (ISO) was founded in 1946 in Geneva, Switzerland. Its mandate is to promote international standards to facilitate the global exchange of goods and services.

• ISO consists of over 90 member countries. Representatives include the American National Standards Institute (ANSI) for the United States and the Bureau of Indian Standards (BIS) for India.

• The ISO Technical Committee (TC) 176 developed the first international standards for quality systems, published in 1987.

• The ISO 9000 series (comprising 9000, 9001, and 9004) was originally advisory for two-party contracts and internal auditing but became universally accepted due to adoption by the European Community (EC).

• The fourth edition of ISO 9001, released in 2008, replaced the 2000 edition to clarify text and enhance compatibility with ISO 14001:2004.

• In the United States, national standards are published by the American National Institute/American Society for Quality (ANSI/ASQ) as the ANSI/ASQ Q9000 series.

• Government agencies utilizing these standards include the U.S. Department of Defense (DOD) and the Food and Drug Administration (FDA).

Audit Systems and Registration Benefits

• Two-Party System: The supplier develops a system, and the customer audits it. This often leads to multiple costly audits for both parties.

• Third-Party Registration: Replaces the two-party system. A registrar (third party) assesses the supplier's system and issues a certificate of registration. This ensures customers that a quality system is in place and being monitored through periodic surveillance audits.

• Drivers for Registration: Customer or marketing demands, process improvement needs, and a desire for global deployment. Registration often creates a "snowball effect" as registered organizations require their subcontractors to follow suit.

• Italian Manufacturing Study Research: A study of 100 firms showed significant improvements in:

  • Internal quality: Measured by scrap percentages, rework, and final inspection nonconformities.

  • Production reliability: Measured by breakdowns per month, emergency time, and downtime per shift.

  • External quality: Product acceptance without inspection, reduced claims, and fewer returns.

  • Time performance: Improvements in time to market, on-time delivery, and throughput.

  • Cost of poor quality: Reductions in external nonconformities.

  • Negative finding: Prevention and appraisal costs typically increased.

• AICPA Example: The American Institute of Certified Public Accountants saw a $4\%$ improvement in gross margins after registration, the largest in its history.

ISO 9000 Series of Standards

• The series is generic and applicable to any organization size or sector (manufacturing, service, healthcare, legal, engineering, etc.).

• The Simplified Philosophy: Say what you do, do what you say, then document/prove it.

• ISO 9000:2005 (Quality Management Systems—Fundamentals and Vocabulary): Discusses fundamental concepts and provides terminology.

• ISO 9001:2008 (Quality Management Systems—Requirements): The standard used for registration to demonstrate conformity to customer and regulatory requirements.

• ISO 9004:2000 (Quality Management Systems—Guidelines for Performance Improvement): Focuses on improving overall performance beyond just meeting requirements.

Sector-Specific Standards

• AS9100 (Aerospace): Released by the Society of Automotive Engineers in May 1997. It unifies requirements from NASA, DOD, and FAA. Aligned with ISO 9001:2000 in March 2001. Revision C was released in January 2009.

• ISO/TS 16949 (Automotive): Harmonizes quality requirements for U.S. (Chrysler, Ford, GM), French, German, Italian, and Asian automakers. Replaces the obsolete QS 9000. It emphasizes continuous improvement, defect prevention, and reduction of variation/waste. GM reported an $85\%$ improvement in supplier parts-per-million defect rates over five years using QS 9000.

• TL 9000 (Telecommunications): Developed by the QuEST Forum (e.g., Motorola, Lucent, Verizon, AT&T). It has a five-layer structure:

  • Layer 1: ISO 9001 requirements.

  • Book 1 (QSR): Common requirements plus specific hardware, software, and services requirements.

  • Book 2 (QSM): Common industry measurements (e.g., billing errors) plus specific hardware, software, and services measurements.

  • Metrics are administered by the University of Texas at Dallas (UTD), providing anonymous benchmarking data like mean, range, median, and standard deviation.

ISO 9001 Requirements (Analysis of Clauses)

The Process Approach

The standard emphasizes understanding/fulfilling requirements, considering processes for value added, obtaining results for performance/effectiveness, and continual improvement based on objective measures.

Clause 4: Quality Management System (QMS)

Implementation and Documentation Hierarchy

Steps for Implementation

1. Top Management Commitment: CEO must commit the necessary resources.

2. Appoint Management Representative: Coordination contact for internals/externals.

3. Awareness: Training sessions (e.g., Habibganj station was the first ISO certified railway station in India).

4. Implementation Team: Cross-functional team to identity processes.

5. Training: Seminar-based training for the audit team and supervisors.

6. Time Schedule: Usually takes less than $1.5$ years.

7. Select Element Owners: Assign responsibilities for specific standard sections.

8. Review Present System: Perform a gap analysis.

9. Write Documents: Draft manuals and work instructions (Case: Stream International encouraged employees to document processes).

10. Install New System: Document daily operations.

11. Internal Audit: Verify effectiveness.

12. Management Review: Determine goal achievement.

13. Preassessment: Optional preparedness check.

14. Registration: Choose registrar and undergo audit.

The Documentation Pyramid

1. Tier 1: Policy: "What" and "Why". Stated as the overall quality intentions (e.g., TVS Logistics Services Ltd policy).

2. Tier 2: Procedures: "Who", "When", and "Where". Strategy for fulfilling policies.

3. Tier 3: Work Instructions: "How". Specialized details (drawings, recipes, routing sheets).

4. Tier 4: Records: "Proof". Traceability and evidence that instructions were followed.

Effective Document Writing

• Aim for simple, concise text (8th-grade reading level, 13-14pt font).

• Use a standard numbering system (e.g., "QPol" for policy, "QPro" for procedures).

• Focus on flow diagrams and self-explanatory check sheets to reduce verbiage.

Internal Audits and Registration Process

Audit Techniques

• Methods include examination of documents, observation of activities, and interviews.

• Interviewing Styles:

  • Open: "How is…?" (Best for opinions/explanations).

  • Closed: "Do you have…?" (Best for quick facts).

  • Clarifying: "Tell me more…" (Prevents misunderstandings).

  • Leading/Aggressive: Should be avoided as they bias findings or create offense.

• Audit Findings: Nonconformance reports must include target element, location, objective evidence, and specific requirement language.

Selecting a Registrar

• Boards include RAB (USA) and NABCB/QCI (India).

• Criteria: Industry experience, customer satisfaction survey ratings (e.g., Quality Digest), certificate recognition, and auditor qualifications (ISO 19011).

• The Steps: Application -> Document Review -> Preassessment (Optional) -> Assessment (Audit) -> Registration -> Periodic Surveillance.

• Registration is typically valid for three years, with surveillance every six to twelve months.

Environmental Management System (ISO 14000)

• ISO formed SAGE in 1991 and TC 207 in 1992 to develop environmental management standards.

• These are process standards, focusing on the process rather than the end goal (similar to ISO 9000).

• ISO 14001: The specific requirements standard for registration.

• ISO 14004: Guidelines on principles and supporting techniques.

• ISO 19011: Replaces older auditing standards; provides unified guidelines for quality and environmental audits to reduce duplicate efforts.

• ISO 14031: Guidelines for recording and tracking environmental performance.

• World's largest supplier of mid-range gas turbine systems.

• Employs 6,200 people (80% in US, 20% across 23 nations).

• Hallmarks: Strategic planning, teamwork, and an unique "authority delegation process".

• Training expenditure: Equivalent to approximately $15\%$ of payroll.

• Cycle time improvement: New product development cycle trimmed from $39$ months to $22$ months since 1994.

• Quality results: Maintenance costs for Solar-made turbines are $42\%$ lower than the industry average.
