Nonconformity Management: Best Practices and Strategies

Managing nonconformities is a key aspect of maintaining quality in any organization. Nonconformity refers to instances where a process, product, or system fails to meet specified requirements. In regulated industries such as manufacturing, pharmaceuticals, or medical devices, nonconformity management ensures compliance with quality standards and regulations. This blog explores non-conformity in detail, covering its types, prevention strategies, best practices, and guidelines for effective management.

What is Nonconformity?

Nonconformity occurs when a product, service, or process does not meet established standards, specifications, or regulations. In simpler terms, it is a deviation from expected performance, leading to quality issues. Nonconformities can stem from poor materials, inefficient processes, inadequate quality control or human error. These deviations can occur at any stage of production, from design to delivery.

Nonconformities are red flags that identifies the gap between the desired outcome and the actual result prompting organizations to take corrective action. By identifying and addressing nonconformities, businesses can continuously improve their processes and maintain product quality.

Nonconformity management is vital in maintaining compliance with industry regulations such as ISO 9001, ISO 13485, and others. Organizations must have systems in place to identify, document, and resolve nonconformities while also taking proactive measures to prevent from recurring.

Nonconformity in ISO: Explained

The International Organization for Standardization (ISO) outlines specific guidelines for managing nonconformities across various industries. ISO 9001, the international standard for quality management systems (QMS), provides a framework for organizations to manage nonconformities systematically.

ISO 9001 requires organizations to detect nonconformities, document them, and take appropriate corrective and preventive actions. The standard emphasizes a process-based approach to quality management, where nonconformities must be addressed within the context of the entire QMS.

Key ISO 9001 clauses related to nonconformity management include:

1. Clause 8.7 – Control of Nonconforming Outputs: This clause requires organizations to ensure that products, services, or processes that fail to meet requirements are identified, controlled, and corrected. Nonconforming outputs must not be delivered to customers unless the issue has been resolved and documented.
2. Clause 10.2 – Nonconformity and Corrective Action: Clause 10.2 outlines the steps organizations should take to address nonconformities, including identifying the issue, determining its cause, and taking corrective action to prevent recurrence.

Other industry-specific ISO standards, such as ISO 13485 for medical devices and ISO 45001 for occupational health and safety, also provide nonconformity management requirements. These standards ensure that organizations maintain compliance and continuously improve their processes.

Types of Nonconformity

Nonconformities can be classified into several types, depending on the nature and impact of the deviation. Understanding these types helps organizations take appropriate corrective actions. Below are common types of nonconformity:

1. Product Nonconformity: This occurs when a product fails to meet the intended quality or performance criteria. It can result from design flaws, manufacturing defects, or substandard materials. For instance, a medical device that malfunctions would be considered nonconforming.
2. Process Nonconformity: A process nonconformity occurs when a procedure or operation deviates from established requirements. This might happen due to incorrect execution or failure to follow standard operating procedures (SOPs). Such deviations can lead to inefficient production and increased costs.
3. System Nonconformity: System nonconformity occurs when the overall management system fails to meet established standards. For example, if a company’s quality management system does not meet the standards set by ISO 9001, it would be classified as a system nonconformity. Such nonconformity often requires changes in documentation, policies, or procedures.
4. Regulatory Nonconformity: Regulatory nonconformity occurs when an organization fails to comply with industry regulations. This can lead to fines, penalties, and damage to the organization’s reputation. Examples include non-compliance with FDA requirements in pharmaceuticals or safety standards in the automotive industry.
5. Out of Tolerance (OOT)/Out of Specification (OOS) Nonconformity: OOT/OOS nonconformity occurs when a product or process measurement deviates from the specified parameters. This indicates that it does not meet the established standards. For example, if a manufacturing process requires a specific dimension to be within 0.5mm, and a product measuring 0.7mm would be considered OOT and nonconforming. Additionally, a product would be deemed OOS if its color is wrong, even if its dimensions are within tolerance. Recognizing the type of nonconformity is the first step toward addressing it effectively.

Examples of Nonconformity

Real-life examples provide insight into how nonconformities can manifest and the importance of addressing them swiftly.

• Automotive Recall Due to Defective Airbags: In the early 2000s, a major automobile manufacturer recalled millions of vehicles due to defective airbags. The airbags deployed incorrectly, causing injuries and deaths. This product nonconformity led to a costly recall and damaged the company’s reputation.
• Pharmaceuticals: In the pharmaceutical industry, even minor deviations from established quality standards can result in serious nonconformity. For example, a drug manufacturer might face regulatory action if a batch of medication fails to meet potency or purity standards. These nonconformities pose a significant health risk to patients and may necessitate product recalls.
• Construction Industry: A construction company using substandard materials in a project could face nonconformity issues. Structural defects resulting from such materials can pose significant safety risks, requiring expensive repairs, delays, and potential legal liabilities.
• Food Industry: A food manufacturer can face severe nonconformities if their products contain undeclared allergens. Regulatory authorities may recall such product, and the company must implement corrective action to ensure compliance with food safety regulations. 

These examples demonstrate the wide-ranging effects of nonconformity across industries. 

Tips to Prevent Nonconformity

Preventing nonconformity requires proactive measures throughout the production and management process. Here are some effective strategies for prevention: 

• Regular Audits: Conduct internal and external audits to ensure processes and products meet required standards. Audits identify potential issues before they escalate into nonconformities.
• Training and Education: Provide regular training for employees to ensure they understand standard operating procedures (SOPs) and quality requirements. Well-trained staff are more likely to adhere to establish processes and identify potential issues.
• Supplier Quality Management: Establish strong relationships with suppliers and collaborate with them to ensure they adhere your quality standards. Poor-quality materials from suppliers are a common source of nonconformity. Regular supplier evaluations and audits can significantly reduce this risk.
• Standardized Processes: Develop and implement standardized processes for production, quality control, and documentation. Clear and well-defined procedures reduce the likelihood of process deviations, ensuring consistency and efficiency throughout operations.
• Risk Management: Incorporate risk management into the quality system. Identify potential risks and establish effective controls to mitigate them. This prevents nonconformities related to unforeseen issues.
• Clear Communication: Maintain open communication between departments and teams. Teams being on the same page, reduces the likelihood of misunderstanding and errors.

Best Strategies for Handling Nonconformity

Effectively handling nonconformity requires a structured approach. The following practices and strategies help organizations manage and resolve nonconformities:

1. Documenting: Timely and a well-written nonconformity statement is crucial for documenting and addressing quality issues.
2. Immediate Containment: As soon as a nonconformity is identified, immediate action should be taken to contain the issue. This may involve halting production, isolating defective products, or temporarily suspending certain processes to prevent further damage.
3. Root Cause Analysis: Identify the root cause of the nonconformity using tools such as the 5 Whys or fishbone diagram. Understanding the underlying issue ensures that corrective actions address the actual problem, not just the symptoms.
4. Corrective Action: Implement corrective actions to eliminate the cause of the nonconformity. Corrective actions should be documented and evaluated to ensure effectiveness. If the nonconformity is due to a process failure, the procedure may need to be revised.
5. Preventive Action: In addition to corrective action, take preventive measures to avoid future nonconformities. These actions should address potential risks and improve overall system robustness.
6. Verification of Effectiveness: After implementing corrective actions, verify that they have resolved the nonconformity. This may involve retesting products, reviewing processes, or conducting audits to ensure the issue is fully resolved.

Handling nonconformities efficiently protects product quality, customer satisfaction, and regulatory compliance.
