A validation master plan (VMP) organizes a validation project. The document can be used to define what to validate, why, who owns the work, and the order of execution. This allows the validation team and those involved to operate from the same approved plan before execution begins.
When that plan is missing or incomplete, problems can surface during project activities. If validation begins before the design and process are settled, validation rework may be required. Without a strong and organized validation master plan, adjusting to design and process changes may open the project up to unforeseen delays.
Months or years later, future project teams may struggle to locate the objective evidence behind prior validation decisions. These gaps expose them to unplanned rework and additional validation that was never part of their project scope.
In this guide, we walk through what a VMP is, whether it is required, and what it should include to close those gaps.
What Is a Validation Master Plan?
A validation master plan does not contain the protocols or test results. It indexes them.
Installation, operational, and performance qualification (IQ, OQ, and PQ) protocols and their reports live in separate documents. The VMP brings together the process outline as it relates to validation, risk assessments, and rationale. This allows anyone reviewing the VMP to see what is being done and why.
Why a VMP Matters
The catch-all capability of the VMP is what makes the document so valuable. It documents the who, what, where, when, and why of validation in one place, whether the records sit on paper or in a digital validation system.
The value is most evident when a company wants to organize multiple products or processes into one clear, concise validation location. This allows future teams to understand earlier decisions.
Other Names for a Validation Master Plan
Some organizations call it a master validation plan or a matrix validation plan, and commissioning programs may use a commissioning and qualification master plan (CQMP). Terminology varies by organization, but the document serves the same purpose.
Site-Level vs. Project-Level VMPs
A site-level VMP covers a facility’s overall validation program and sets the intervals for periodic requalification. A project VMP covers a single effort, such as a new product introduction, and closes once the product launches.
When Is a VMP Written?
A VMP is typically written before commissioning and qualification (C&Q) begin, once the design and process steps are stable enough to plan against. A project VMP can then be revised as testing progresses, up until the product launches.
Is a Validation Master Plan Required?
It depends on the regulatory framework. The European Union’s good manufacturing practice (GMP) guidelines require a VMP or an equivalent document. In the United States, the Food and Drug Administration (FDA) does not require a document by that name. Still, its regulations require planned and documented validation, and a VMP is a common way to meet that expectation.
EU GMP and PIC/S Requirements
EU GMP Annex 15, the qualification and validation annex to the European Union’s GMP guidelines, requires a VMP or an equivalent document. The Pharmaceutical Inspection Co-operation Scheme (PIC/S), an international network of more than 50 GMP inspectorates, applies an equivalent annex.
At a minimum, Annex 15 expects the plan to include or reference:
- The validation policy
- The organizational structure, including roles and responsibilities
- A summary of facilities, equipment, systems, and processes, with their validation status
- Change control and deviation management
- Guidance on developing acceptance criteria
- References to existing documents
- The validation strategy, including requalification
FDA Expectations
For drug manufacturers, the FDA’s current good manufacturing practice (CGMP) regulations in 21 CFR Parts 210 and 211 require process validation, and the agency’s process validation guidance expects that work to be planned and documented across the product lifecycle.
For medical device manufacturers, the FDA’s Quality Management System Regulation (QMSR), which incorporates ISO 13485:2016, requires validation of any process whose output cannot be fully verified through later inspection or testing. Under either framework, the reasoning behind each validation decision belongs on record alongside the results.
What Should a Validation Master Plan Include?
Annex 15 defines the minimum. Beyond that, a VMP can be as detailed as its author chooses, and more detail generally makes the plan easier to defend, because each documented decision is one the next team will not have to reconstruct.
In practice, a VMP can be organized into five working sections, and the order matters. Scope comes first, because every decision that follows depends on where the plan’s boundaries sit.
1. Scope
The VMP scope sets the high-level boundaries of the validation covered in the document. The scope specifies what facilities, processes, and systems are included and what is considered out of scope.
Once the boundaries are set, the next question is who owns the work inside them.
2. Roles and Approvals
A VMP draws on several functions, each owning a distinct piece of the work. A typical plan defines the following roles:
- Author: Often an external validation partner responsible for writing the plan and its protocols and for executing deliverables.
- Process Engineers: Typically in a Manufacturing Operations R&D role, they develop the process and provide the author and team with risk documents, equipment details, and user manuals.
- Quality Assurance Engineer (QAE): The quality approver, responsible for reviewing and monitoring the validation efforts to ensure quality and safety standards are met.
- Process Owner: A designated lead from operations or project management who is responsible for the business process that the validation is supporting.
- Validation Approver: The authorized role or individual responsible for reviewing validation deliverables to determine whether they meet internal validation requirements and international or technical standards.
Naming each role in the VMP gives every protocol a clear sign-off path, allowing for a streamlined review and approval process. With ownership settled, the plan can address the harder question: how much validation the facility, process, or system in scope actually needs.
3. Risk Assessment, Validation Strategy and Documentation
Not every deliverable within the determined validation scope requires the same testing, and the validation strategy is where the team makes and justifies that decision.
It begins with an Impact Assessment (IA). This evaluation determines whether a facility, utility, system, equipment, or process has a Direct Impact (should be commissioned and qualified) or an Indirect Impact (will only be commissioned) on process and product quality.
Once the evaluation is complete, the team begins qualifying items with Direct Impact and logs that work in the VMP. Depending on the validation required, the VMP can include the following activities:
- Commissioning: Verifies that the facility, utility, and equipment (the “system”) are installed properly, function properly, and have the correct utilities connected.
- FAT (Factory Acceptance Test): Provides documented evidence that a piece of equipment or system has been adequately tested at the manufacturer’s facility and meets the end user’s expectations before delivery.
- SAT (Site Acceptance Test): Provides documented evidence that a piece of equipment or system has not been affected in transportation, has been adequately tested at the end user’s facility, and performs to the end user’s expectations.
- IQ (Installation Qualification): Documentation that verifies all aspects of a facility, utility, or equipment that can affect product quality adhere to approved specifications and are correctly installed.
- OQ (Operational Qualification): Documentation that verifies the facilities, systems, and equipment, as installed or modified, operate as intended throughout the anticipated operating ranges.
- PQ (Performance Qualification): Documentation that provides assurance the equipment and system function accurately and consistently according to predetermined specifications within the anticipated operating ranges.

4. Acceptance Criteria and Decision Rationale
As previously mentioned, the VMP is an index of the validation activities determined to be in scope of the project. The VMP can note where acceptance criteria can be found for equipment or processes within the validation scope.
For example, a system design and associated process requirements are captured in a User Requirement Specification (URS). That document is reviewed and approved outside of the VMP. The VMP captures any rationale or leveraging decisions that coincide with in-scope validation deliverables.
The applicable acceptance criteria, rationale decisions, and leveraging opportunities create traceability from a single source. This makes it easier for reviewers and future teams to understand the validation efforts conducted and why.
5. Change Control and Deviations
Few validation projects remain static before launch. One of the most common sources of rework is developing and executing validation deliverables too early, before process steps are finalized. This can lead to repeated validation activities that a project team may not have budgeted for.
Some changes are unavoidable, and with a strong VMP, the impact of process changes is easier to identify, so the team can update validation deliverables, rationale, and language to streamline any revalidation efforts, if necessary.
A project VMP can be revised until launch. After launch, teams handle changes through a separate validation project or a smaller VMP, while risk assessments, which are utilized by the VMP, remain open as living documents across the product lifecycle.

Conclusion
A VMP is often treated as paperwork written after the planning is done. In practice, it is the planning. The scope, ownership, strategy, acceptance criteria, deliverables, rationale, and change controls it defines determine whether validation proceeds in an effective and timely manner or results in potential rework or ambiguous validation decisions.
Performance Validation (PV) brings certainty to that planning. Clients often come to PV with equipment installed and ready for qualification, but without a clear view of which validation activities they need. PV engineers review the process end to end, then define exactly what validation the project needs and why.
Because they support pharmaceutical and medical device programs, PV engineers are fluent in both industries’ validation terminology. With PV’s expertise in commissioning, qualification, and validation, clients receive detailed documentation structured for regulatory review.
