Contract Development and Manufacturing Organizations (CDMOs) operate on aggressive timelines. Speed to market is essential, so production must come online quickly. Every phase of facility construction and system startup becomes a race against the calendar. In these aggressive, schedule-driven environments, it is common for Commissioning, Qualification, and Validation (CQV) tasks and deliverables to be scheduled near the end of the project. CQV is the last discipline to finish, so it is assumed that facility, utility, and equipment installation and electrical/mechanical completion milestones must be completed before CQV begins.

In practice, this end of schedule CQV creates risk. When the CQV team is brought in late in the project timeline, they typically discover missing specifications, undocumented requirements, or system designs that are not GMP-compliant. Closing these compliance gaps during qualification requires formal deviation records and remediation plans, which in turn result in schedule delays that ripple through the production timeline.

Bringing CQV into a project near the finish line leaves little room to correct problems that began months earlier. However, most of these challenges are avoidable if CQV expertise is embedded earlier in the process.

Indicators that CQV was brought in late

Across the CDMO sector, experienced CQV professionals see a repeating pattern: CQV becomes a bottleneck because it was not built into the project plan from the beginning. Some warning signs include:

• CQV appears as the final project milestone instead of a series of activities integrated throughout the project.
• The project has no clear change control strategy.
• User requirements, risk, and impact assessments are incomplete or unapproved when CQV execution is scheduled to begin.
• Equipment procurement begins before the CQV team can establish vendor document requirements.
• Ownership of the systems required to maintain a validated state is not defined (i.e., standard operating procedures, calibration tasking, preventive maintenance tasking).
• Templates are not yet established for verification testing, traceability matrices, turnover packages requirements, etc.
• The CQV team uncovers design gaps, missing documentation, or systems that do not fully support GMP-compliant operation.
• Design changes occur without a documented impact assessment.
• Deviations, remediation plans, and documentation rework are prevalent.
• The project team relies on informal communication rather than structured document management and approval workflows.

Embedding a CQV expert early can help facilities avoid most of the problems.

Embedding CQV expertise across the project lifecycle

CQV delivers the best value when it is integrated across the full project life cycle rather than being deferred to the end. When CQV specialists get involved early, they can influence design decisions and help create a realistic CQV schedule.

CQV planning as an output of design definition

The optimal time to involve CQV specialists is during the design definition phase, while facility design and process flows are still being developed. An early review of preliminary P&IDs helps the CQV team establish the overall CQV approach and timeline for the rest of the project.

Early CQV involvement helps teams spot potential issues before they become expensive to fix. A system may look complete from an engineering standpoint, yet the submittal package may still lack the supporting documentation or functional requirements needed for validation.

Once the project definition is complete and the design is underway, the CQV team has enough information to begin developing the project Commissioning / Qualification / Validation Plan (CQVP). The CQVP defines the policies, approaches, and procedures for executing CQV. It also classifies the GMP impact of each system and identifies the deliverables required to verify compliance. A complete CQVP can also serve as the CQV request-for-quote by setting clear expectations for prospective service providers.

Experienced CQV professionals providing input during design definition can add significant value. The goal is to align engineering decisions with regulatory expectations as early as possible.

CQV input into the project schedules

Project schedule input is critical to successful CQV execution. Effective CQV relies on milestones for equipment delivery, installation, mechanical completion, and commissioning/qualification readiness. Without those dependencies, CQV can slip into a compressed window at the end of the project.

Embedded CQV specialists can help build dependencies into the schedule, so CQV activities progress in sequence. Essential activities like Factory Acceptance Testing, system startup, and commissioning turnover become planned events rather than last-minute additions.

Early CQV planning also establishes execution milestones. When equipment installation, commissioning, and qualification are scheduled effectively, the project follows a structured, proactive sequence with fewer unscheduled emergencies.

CQV deliverable preparation

CQV is fundamentally a documentation-driven process. Whether the approach is paperless or hard copy, every qualified system requires verification protocols, final reports, SOPs, calibration records, and change control documentation that can withstand regulatory scrutiny. Establishing this documentation framework early helps prevent major disruption later in the project.

A clear understanding of the client’s document management and change control systems improves coordination across design, construction, CQV, and quality teams. As construction progresses, information flows through structured workflows rather than informal communication channels.

Formal (documented) commissioning verification can simplify later qualification via the risk-based approach. With Quality unit approval, verification testing completed during commissioning can be leveraged to support installation qualification, reducing duplicate testing and helping keep validation schedules on track.

CQV site presence during construction

The embedded CQV specialist plays a key role during construction and commissioning. Because they are present throughout the project, they develop a detailed understanding of the facility, the equipment being installed, and the contractors performing the work.

This level of continuity allows them to monitor design changes and construction decisions that could affect downstream CQV. Their presence also strengthens communication between engineering, construction, and the CQV team.

Making early CQV involvement work

Embedding CQV expertise early in a project requires an organizational structure that supports it. Facilities that succeed with this embedded model typically assign strong project management leadership alongside the CQV team.

A dedicated project manager maintains the master schedule, tracks dependencies, and holds teams accountable for deliverables that affect validation readiness. Without this structure, projects drift into a series of recurring meetings where the same issues are discussed week after week without clear task ownership.

An approved responsibility matrix is equally important, including:

1. Ownership of procedure development, maintenance programs, and calibration tasking
2. Responsibility for protocol review and approval

Both are necessary to maintain a system’s validated state. Assignment of ownership early keeps those foundational elements from becoming last-minute obstacles. With the right structure in place, early CQV involvement becomes a practical strategy rather than an additional layer of complexity.

How can Salas O’Brien help?

Your facility startup depends on more than construction milestones. GMP compliance determines when production can begin and how smoothly regulatory inspections will proceed. Bringing CQV expertise into the project early aligns engineering decisions with compliance requirements helps reduce downstream deviations.

At Salas O’Brien, you gain access to multidisciplinary teams that integrate engineering, commissioning, and validation planning from the start of your project. We support CQV for CDMO projects by:

• Embedding experienced CQV professionals during early planning and design
• Developing CQV master plans and validation strategies
• Incorporating CQV milestones into the construction schedule
• Designing systems that support efficient qualification and long-term compliance

If you are planning a new facility or a facility expansion, our team can help you incorporate CQV expertise at the stage where it has the greatest impact. Contact us at [email protected].
