Commissioning, Qualification, Validation – Because ‘It Should Work’ Isn’t a Strategy
Understanding the Differences Between Commissioning, Qualification, and Validation
In industries like commercial construction, pharmaceuticals, biotech, and manufacturing, ensuring that buildings, systems, and equipment operate correctly is a critical process. Three key terms often used interchangeably—but with distinct meanings—are Commissioning (Cx), Qualification (Q), and Validation (V). They might sound like jargon-y synonyms at first glance, but each one plays a distinct role in ensuring systems, equipment, and processes work as intended. Understanding their differences is crucial for compliance, operational efficiency, and project success.
So, what sets them apart? Let’s break it down step by step.
What Is Commissioning (Cx)?
Commissioning is a systematic quality assurance process that verifies and documents that facilities, systems, and equipment are designed, installed, and function according to the owner’s requirements.
Imagine you are about to buy a shiny new car. Before you drive it off the lot, you take it for a test drive and check that the engine starts, the brakes work, and the lights turn on. That’s a bit like commissioning—it’s the initial verification after getting a system or piece of equipment up and running before the owner takes acceptance.
Commissioning happens early in the lifecycle of a project, often during or right after installation. It’s about testing and tweaking to confirm that everything was built and set up according to the design specifications. Think of it as the “does it turn on?” phase. For example, in a pharmaceutical plant, commissioning might involve powering up a new mixing tank, checking its motors, and ensuring the pipes don’t leak. It’s practical and hands-on, focused on functionality rather than proving anything to regulators.
Key Characteristics of Commissioning:
Ensures mechanical, electrical, plumbing (MEP), HVAC, fire protection, and other building systems function as intended.
Performed in commercial, industrial, and healthcare facilities.
Involves design review, installation inspections, functional testing, and operator training.
Not a regulatory requirement, but an industry best practice for system performance and energy efficiency.
Commissioning Process Steps:
Pre-Design Phase: Establish Owner’s Project Requirements (OPR).
Design Phase: Review specifications to align with performance goals.
Construction Phase: Verify installation and conduct preliminary testing.
Functional Testing: Ensure systems operate per design.
Post-Occupancy Phase: Monitor system performance and provide documentation.
Key takeaway: Commissioning is about making sure the system works as built, like a first test drive.
What Is Qualification (Q)?
The Code of Federal Regulations (CFR) defines the rules published by the Federal Government. Title 21 of the CFR is reserved for the FDA. 21 CFR Part 210 & 211 defines current Good Manufacturing Practice (cGMP) The drug manufacturer must prove (document) that they have adhered to 21 CFR. This necessitates validation and Good Documentation Practices (GDP). Qualification is a process that documents through GDP guidelines ensuring the quality of medicines throughout the supply chain.
Qualification applies to regulated industries such as pharmaceuticals, biotechnology, and medical devices. It ensures that critical systems and equipment meet specific regulatory requirements and operate within predefined limits. Qualification is more formal than commissioning and often splits into stages like Installation Qualification (IQ), Operational
Qualification (OQ), and sometimes Performance Qualification (PQ). IQ checks that the equipment is installed correctly (e.g., “Is the mixing tank bolted down properly?”). OQ tests that it operates as expected under specific conditions (e.g., “Does it mix at 500 RPM when set to that speed?”). PQ, if included here, might overlap with validation—we’ll get to that in a sec. Qualification is heavily documented because it’s often required by regulatory bodies like the FDA or ISO standards.
Types of Qualification:
Design Qualification (DQ): Ensures that the system’s design meets operational and regulatory needs.
Installation Qualification (IQ): Confirms that equipment and systems are installed per specifications.
Operational Qualification (OQ): Verifies that systems function correctly under standard conditions.
Performance Qualification (PQ): Ensures that systems perform consistently under real-world operating conditions.
Industries That Require Qualification:
Pharmaceuticals and biotechnology
Medical device manufacturing
Food and beverage production
Cleanrooms and controlled environments
Commissioning Vs Qualification – Validation Master Plan
The scope delineation between systems that are included in Commissioning vs Validation (with possible overlaps) comes from the Validation Master Plan (VMP A Validation Master Plan (VMP) is a high-level document that outlines an organization’s overall strategy, approach, and responsibilities for validating systems, processes, and equipment in regulated industries such as pharmaceuticals, biotechnology, medical devices, and food manufacturing. It serves as a roadmap for compliance, ensuring adherence to regulatory requirements like FDA 21 CFR Part 11, GMP, ISO 13485, and EMA guidelines. The VMP provides a structured framework for planning, executing, and documenting validation activities, ensuring that all critical systems consistently function as intended.
A well-structured VMP typically includes several key components. First, the Introduction and Purpose section defines the objective and scope of the validation program, identifying the specific equipment, systems, and processes that require validation. Next, the Regulatory and Compliance Framework references applicable industry regulations and guidelines to ensure alignment with best practices. The Scope of Validation outlines which systems—such as critical utilities, manufacturing equipment, and software—fall under the validation program. Additionally, the Validation Approach and Methodology section describes the step-by-step validation process, including Design Qualification (DQ), Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ).
Another crucial element of the VMP is the Risk Assessment Strategy, which identifies potential risks associated with equipment and processes, helping prioritize validation efforts based on their impact on product quality and safety. Systems are typically delimited between Direct Impact and No Impact.
The plan also defines the Roles and Responsibilities of various stakeholders, such as Quality Assurance (QA), Engineering, the Validation Manager, and Operations personnel, to ensure accountability throughout the validation process. The Documentation and Deliverables section specifies the required protocols, reports, and test scripts, ensuring that all validation activities are well-documented and traceable.
A comprehensive VMP also includes a Change Control and Re-Validation policy to address modifications to validated systems, establishing guidelines on when re-validation is necessary. It further outlines procedures for handling Deviations and Corrective Actions (CAPA) in case validation results deviate from expected outcomes. Finally, the Final Approval and Review Process details how the VMP is reviewed, maintained, and updated over time to ensure ongoing compliance and continuous improvement.
A Validation Master Plan is essential for regulatory compliance, quality assurance, and risk management. It helps organizations maintain consistent validation practices, ensures audit readiness, and provides documented proof of adherence to industry regulations. By implementing a structured VMP, companies can effectively minimize risks, enhance product safety, and maintain regulatory approval.
What Is Validation (V)?
Back to the car analogy: Validation is daily driving your car and constantly chacking that everything still works—consistently and reliably. In technical terms, validation confirms that the entire process or system delivers the intended outcome, not just that individual pieces work.
Validation looks at the bigger picture. Where qualification focuses on equipment or components, validation ensures the whole process—equipment, people, and procedures included—produces the right result every time. For instance, in drug manufacturing, validation might mean running the mixing tank, filling machine, and packaging line together to prove they consistently produce safe, effective tablets. It’s end-to-end assurance, often culminating in a Process Validation that regulators love to see.
Validation is a comprehensive process that ensures a system, process, or piece of equipment consistently delivers results that meet predetermined standards. It includes commissioning and qualification but extends to process verification. Validation ensures manufacturing systems, equipment, and processes consistently produce safe, high-quality products that meet Good Manufacturing Practice (GMP) regulations set by agencies like the FDA, EMA, and WHO. It includes Qualifaciton to confirm that facilities and processes operate reliably and within regulatory standards, but is not a one time event. Validation is an ongoing process that extends for the lifetime of the product.
Key Characteristics of Validation:
Mandatory in regulated industries to comply with FDA, EMA, GMP, and ISO standards.
Focuses on repeatability, consistency, and regulatory compliance.
Applies to entire processes, equipment, and facilities.
Involves extensive documentation, risk assessment, and compliance testing.
Validation Process Steps:
Validation Master Plan (VMP): Defines scope, objectives, and methodologies.
Risk Assessment: Identifies potential failure points.
Equipment & Process Validation: Conducts qualification steps (DQ, IQ, OQ, PQ).
Final Report & Regulatory Submission: Demonstrates compliance with industry standards.

Keys to success for CQV Projects?
Successful Commissioning, Qualification, and Validation (CQV) projects require clear objectives, regulatory compliance, and effective collaboration. Defining a well-structured scope and risk-based approach ensures that critical systems are validated efficiently while minimizing delays. Regulatory awareness of FDA, GMP, and ISO standards is essential to ensure compliance, while thorough risk assessments (e.g., FMEA) help prioritize validation efforts. Cross-functional collaboration between QA, Engineering, and Operations teams, combined with proper documentation of DQ, IQ, OQ, and PQ protocols, ensures traceability and audit readiness. A structured Change Control process is also necessary to manage deviations and modifications while maintaining validation integrity.
Additionally, adequate resource allocation, training, and a proactive testing strategy are key to ensuring CQV success. Comprehensive Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), and process simulations help identify issues early, while continuous monitoring and periodic reviews ensure long-term compliance. A well-documented and systematic approach to CQV helps organizations mitigate risks, streamline validation efforts, and maintain operational excellence. By focusing on these key factors, organizations can achieve regulatory approval, minimize project delays, and ensure validated system performance for long-term success.
Why It Matters
These distinctions aren’t just academic. In regulated industries, skipping or skimping on any of these steps can lead to costly delays, failed audits, or even unsafe products reaching the market. Commissioning saves headaches by catching issues early. Qualification builds trust with regulators. Validation ensures customers get what they expect. Together, they’re the backbone of quality and compliance.
Final Thoughts
Understanding the distinctions between commissioning, qualification, and validation is crucial for ensuring compliance and maintaining the integrity of processes and systems in regulated industries. These three components work together to establish a strong foundation—commissioning verifies system functionality, qualification confirms that equipment meets design specifications, and validation ensures consistent performance under real-world conditions. By integrating these steps effectively, businesses can strengthen compliance frameworks, enhance operational efficiency, and improve product quality and safety. As regulatory landscapes continue to evolve, mastering these principles is key to staying ahead and fostering a culture of excellence in regulated environments.
