 ISO 9001:2015 – Clause 8: Operation


For clause 7- Support: https://qms2025.blogspot.com/2025/11/iso-90012015-clause-7-support.html

Clause 8 of ISO 9001:2015 is considered the heart of the Quality Management System (QMS) because it deals with the actual execution of processes that transform customer requirements into final products or services. While previous clauses focus on planning, leadership, risk analysis, and support, Clause 8 emphasizes real action, real control, and real output.

This clause ensures that operations are carried out in a structured, controlled, and repeatable manner so that organizations consistently meet customer expectations and achieve sustainable quality performance. It integrates planning, execution, monitoring, supplier control, product realization, and handling of nonconformities.

Clause 8.1 – Operational Planning and Control

The first step in effective operations is planning. The organization must identify what needs to be done, who will do it, what resources are needed, and how results will be monitored.

Key requirements include:

  • Identify the processes needed to meet product/service requirements
  • Establish acceptance criteria for processes and outputs
  • Determine required resources (manpower, machinery, methods, and materials)
  • Implement controls to ensure consistency and compliance
  • Retain documented information as evidence of implementation

Purpose:
To ensure that activities necessary to provide quality products or services are carried out in a systematic manner.

If planning is weak, execution will fail—leading to quality issues, customer complaints, and rework.

Clause 8.2 – Requirements for Products and Services

Before doing any work, the organization must clearly understand what the customer expects. Misunderstanding customer requirements is one of the leading causes of quality failures.

8.2.1 Customer Communication

Organizations must establish effective channels for communication regarding:

  • Product/service information
  • Contract or order handling
  • Customer feedback and complaints
  • Changes in products or orders

8.2.2 Determining Requirements

The organization must determine:

  • Customer-specified requirements
  • Legal and regulatory requirements
  • Requirements considered necessary by the organization

8.2.3 Reviewing Requirements

Before accepting an order, the organization must review and ensure:

  • Requirements are clearly understood
  • The organization has the capability to meet them
  • Any differences or gaps are resolved

8.2.4 Changes in Requirements

Any changes must be controlled and communicated to relevant stakeholders.

Objective:
Avoid surprises or mismatches between expectations and delivery.

Clause 8.3 – Design and Development of Products and Services

If an organization designs products or services, it must control the entire design process to prevent the delivery of defective or unsafe solutions.

Key steps include:

  • Design planning: Define stages and responsibilities
  • Inputs: Collect requirements, regulations, previous performance data
  • Outputs: Develop specifications, drawings, formulas, software models, etc.
  • Review, verification & validation: Check functionality and performance
  • Design changes: Must be documented, reviewed, and verified

Design controls reduce risk, cost, and time related to post-launch failures.

If design and development are not applicable (e.g., trading companies), the organization must justify the exclusion.

Clause 8.4 – Control of Externally Provided Processes, Products & Services

Suppliers and outsourced services significantly affect product quality. Poor supplier performance leads to delays, failures, and customer dissatisfaction.

Requirements include:

  • Evaluating and selecting suppliers based on capability
  • Monitoring supplier performance and quality
  • Verifying purchased materials before use
  • Clearly communicating requirements to suppliers

Goal:
Ensure external inputs do not compromise output quality.

Clause 8.5 – Production and Service Provision

This section covers the execution stage of production and service delivery. It includes:

8.5.1 Control of Production and Service Provision

Organizations must implement controls such as:

  • SOPs, work instructions, control plans, or process sheets
  • Suitable equipment and competent personnel
  • Monitoring and measurement activities

8.5.2 Identification and Traceability

Products must be identifiable throughout production.

8.5.3 Customer Property

Take care of customer-owned equipment, materials, and data.

8.5.4 Preservation

Protection from damage, corrosion, contamination, or deterioration.

8.5.5 Post-delivery Activities

Include warranty, servicing, recycling, recall, etc.

8.5.6 Control of Changes

Production process changes must be evaluated and approved to prevent errors.

Clause 8.6 – Release of Products and Services

Before delivery, the organization must:

  • Inspect or test outputs
  • Ensure acceptance criteria are met
  • Retain evidence (inspection reports, test certificates)
  • Release only after authorization by trained personnel

This prevents accidental shipment of defective outputs.

Clause 8.7 – Control of Nonconforming Outputs

When something goes wrong, the organization must take corrective steps:

  • Identify the nonconforming output
  • Prevent unintentional use or shipment
  • Segregate or label defects
  • Inform customers if required
  • Take corrective actions
  • Maintain records

Goal:
Prevent defects from reaching the customer and avoid repetition.

Conclusion

Clause 8 ensures that real operations are executed with control, discipline, and consistency. When implemented effectively, organizations experience:

✔ Reduced defects and rework
✔ Higher productivity and efficiency
✔ Improved customer satisfaction
✔ Better process consistency
✔ Strengthened brand trust

Simply stated:
Clause 8 converts planning into performance and customer needs into successful outcomes.

Statistical Process Control (SPC)

Statistical Process Control (SPC) In modern manufacturing, consistent quality is no longer a luxury — it is a non-negotiable requirement. Customers demand zero-defect performance, reliable deliveries, and repeatable precision every time. Competitive industries such as automotive, aerospace, machining, surface treatment, fabrication, electronics, and plastics operate under strict control standards where even small deviations can lead to massive consequences — from rework and downtime to field failures and recalls. However, maintaining such consistency cannot be achieved by inspection alone . Checking quality after production only identifies problems once they have already occurred, leading to waste, delays, and customer dissatisfaction. To meet today’s expectations of reliability and efficiency, organizations must monitor the process continuously and prevent defects before they happen. This is exactly where Statistical Process Control (SPC) becomes one of the most valuable and powerful...

Internal audit & why it is importance in ISO 9001

What is INTERNAL AUDIT & Why It Is Important in ISO 9001 Introduction Internal audits play a crucial role in ensuring the effectiveness of a Quality Management System (QMS). They act as an internal checkpoint to verify whether processes are functioning as intended, employees are following documented procedures, and improvement opportunities are identified before issues escalate. In simple terms, internal audits help organizations remain compliant, consistent, and continually improving. They are not meant to point fingers or find fault, but to strengthen the organization and support improvement. A strong internal audit system ensures that quality is not just a document on paper—it is a disciplined way of working that leads to reliability, customer satisfaction, and sustained business growth. Additionally, internal audits encourage transparency, accountability, and data-driven decision-making at every level of the organization. When performed effectively, they help teams under...
