Validation Protocol in the Pharma are same “Imagine building a skyscraper in the heart of a bustling city. You don’t pour concrete without drawings. You don’t weld beams without approvals”. Similarly, in the pharmaceutical industry, we don’t validate equipment, systems, or processes without a Validation Protocol — the industry’s blueprint of trust.
This article will take you through how to write a Validation Protocol in a construction project metaphor, ensuring it’s engaging, easy to understand, and methodologically sound.
A Validation Protocol in the pharmaceutical industry is a pre-approved, documented plan that outlines the objective, scope, responsibilities, procedures, acceptance criteria, and documentation requirements necessary to carry out the validation of a process, system, equipment, or method to ensure it consistently performs as intended and complies with regulatory and quality standards.
(Simple Definition ):
“A validation protocol is a written plan that defines how a system, equipment, or process will be tested to confirm that it works correctly and consistently, ensuring product quality and patient safety.”
Types of Validation:
Let’s represent the types of validation using a metaphor of “Time Travelers”, each traveling through different phases of the process lifecycle:
Step 1: Name the Production (Title Page)
Action: Give your protocol a formal identity.
Include:
- Title (e.g., Validation Protocol for Blister Packaging Machine XYZ)
- Protocol Number
- Document Revision History
- Approval signature lines
Step 2:Objective & Scope
Action: Clearly define what you’re validating and why.
Example:
“The objective of this protocol is to validate the operational performance and compliance of XYZ Tablet Press, ensuring it meets user-defined requirements under GMP conditions.”
Step 3: Assign Cast & Crew (Responsibilities)
Action: Define who’s doing what.
Typical Roles:
- QA: Review & Approval
- Engineering: Execution & Technical Input
- Validation: Drafting, Execution & Reporting
- Production: User Verification
Step 4: Describe the Set (System/Process Description)
Action: Provide a technical overview of the system, equipment, or process.
Include:
- Make/model
- Serial numbers
- Utility requirements
- P&ID references or schematic diagrams
Step 5: Define the Genre (Validation Strategy & Approach)
Action: Choose your validation type and methodology.
Options:
- Prospective / Concurrent / Retrospective / Revalidation
- Risk-based strategy (tie into FMEA if applicable)
Step 6: Write the Scenes (Detailed Testing Procedures)
Action: Break down testing into defined phases:
- Installation Qualification (IQ) – Is everything installed correctly?
- Operational Qualification (OQ) – Does it work under expected conditions?
- Performance Qualification (PQ) – Does it perform consistently during real operation?
Each test must include:
- Purpose
- Procedure steps
- Expected results
- Space for actual results
- Deviation handling
Step 7: Insert the Props (Supporting Documents & Attachments)
Action: Reference or attach all relevant documents:
- SOPs
- Drawings
- Calibration reports
- URS
- Certificates
Step 8: State the Ending Criteria (Acceptance Criteria)
Action: For each test, write clear, objective criteria that define “pass” or “fail.”
Example:
“The machine must operate for 3 consecutive hours without deviation or system alarms.”
Step 9: Prepare the Final Scene (Deviation & Change Management)
Action: Include how any deviations from expected results will be handled.
Should cover:
- Deviation logging
- Impact assessment
- Corrective action process
Step 10: Roll the Credits (Review & Approval Page)
Action: The protocol must be reviewed and approved before execution.
Typically signed off by:
- Validation
- Quality Assurance
- Engineering
- End-User/Production
Optional: Step 11: Post-Credit Scene (Linking to Validation Report)
After execution, the results go into a Validation Report, which refers back to this protocol — proving you followed your script.
Final Thoughts: Protocols Are Proof of Discipline
In pharma, writing a validation protocol is not just an academic task — it is a regulatory, ethical, and scientific obligation. It ensures:
- Patient safety
- Product quality
- Regulatory compliance
