Case Study
Validation Strategy & Manufacturing: IQ/OQ/PQ Framework
Defining a multi-site Validation Strategy using a framework that coordinated across contract manufacturers and in-house manufacturing to demonstrate manufacturing process control
The Challenge
Before manufacturing at scale, the company needed to prove contract manufacturers could consistently produce equipment and consumables meeting exact specifications. This required comprehensive validation protocols covering Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) across multiple sites.
The validation complexity stemmed from different contract manufacturers producing various components at separate locations. The company sought expertise to develop validation strategy proving manufacturing process control across all sites.

Company Background
The company was transitioning from product development to manufacturing readiness. With designs finalized and contract manufacturing partnerships established, the next critical step was proving manufacturing processes could consistently produce products meeting all specifications.
While they had established validation protocols for consumable batch processes, capital equipment validation represented different complexity—assembly line manufacturing with components from multiple suppliers requiring coordinated validation across sites.
The Validation Challenge
The company faced several interconnected validation requirements.
Multi-Site Coordination: Contract manufacturers at multiple sites produced different components. Validation protocols needed coordination across suppliers while ensuring consistency in standards and requirements. Each site had its own quality systems, but overall validation strategy needed coherence.
Comprehensive Protocol Framework: IQ/OQ/PQ protocols needed to actually prove process control, not just check compliance boxes. The validation approach required appropriate test methods and acceptance criteria, statistical rigor demonstrating process capability, documentation standards supporting regulatory expectations, and practical execution considering resource constraints.
Regulatory Expectations: Validation documentation needed to satisfy regulatory expectations and support future submissions. Protocols had to be thorough, well-documented, and scientifically sound—demonstrating manufacturing processes were under control.
Integration Across Value Chain: Equipment validation required proving not just individual manufacturing steps, but the complete system including component manufacturing at contract manufacturers, assembly operations integrating components, software installation and functionality, and complete system performance under various conditions.
The company sought specialized expertise in device validation and multi-site manufacturing qualification to develop comprehensive validation strategy and framework.
Our Approach
01 | Three-Phase Validation Strategy Framework
We developed comprehensive validation strategy covering the complete manufacturing value chain through Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ).
The IQ framework proved equipment and facilities were properly installed and configured through equipment installation verification procedures, utilities qualification, facility environmental controls verification, calibration verification for manufacturing equipment, and documentation requirements with acceptance criteria.
Our OQ framework demonstrated manufacturing processes operated within specified parameters through process parameter challenge testing, equipment performance verification across operating ranges, control system functionality testing, alarm and safety system verification, and training verification for operators.
The PQ framework demonstrated consistent output quality over time using production runs simulating commercial manufacturing, statistical analysis of output quality, process capability studies, validation of complete product specifications, and documentation of consistent performance.
We defined validation scope, approach, and responsibilities across sites while creating a master validation plan establishing the overall framework. We identified critical process parameters requiring validation, established acceptance criteria and statistical methodologies, and developed documentation structure and report templates. The strategy balanced regulatory rigor with practical execution, providing clear roadmaps that internal teams and contract manufacturers could follow.
02 | Multi-Site Coordination & Integration
We coordinated validation planning across contract manufacturing sites to ensure cohesive system-level process control. This involved aligning validation approaches while respecting site-specific quality systems, integrating component validation with assembly validation, establishing communication protocols between sites, creating consolidated validation reporting framework, and ensuring documentation consistency across suppliers.
The coordination ensured validation strategy worked as an integrated system rather than isolated site efforts. Despite different quality systems and operational approaches at each site, the framework created cohesive approach demonstrating system-level process control.
03 | Change Control & Continuous Improvement Framework
We established change control processes for post-validation modifications to allow continuous improvement while maintaining validation status. This included classification of changes by validation impact, revalidation requirements for different change types, documentation requirements for approved changes, and communication protocols for changes affecting multiple sites.
The framework provided clear processes for managing the inevitable engineering changes and process improvements that would occur after initial validation while preserving manufacturing process control.
The Impact
Manufacturing Process Control Framework Established
The validation strategy provided comprehensive framework for proving manufacturing process control across all sites. The three-phase IQ/OQ/PQ approach built systematic confidence in manufacturing capability—IQ confirmed equipment and facilities configuration, OQ demonstrated process operation within specified parameters, and PQ proved processes consistently produced products meeting quality specifications.
The protocol frameworks were designed for execution by internal teams and validation specialists, demonstrating that processes could consistently produce products meeting specifications. This framework positioned manufacturing for commercial scale-up with confidence that quality would be maintained as production increased.
Regulatory Compliance & Documentation Framework
The validation strategy created framework for permanent record of manufacturing capability supporting regulatory compliance and quality assurance. The documentation approach provided traceability from requirements through verification, statistical evidence of process capability, baseline data for troubleshooting and continuous improvement, and foundation for future regulatory submissions if needed.
This regulatory documentation framework satisfied compliance expectations while creating practical tools for ongoing manufacturing operations and quality management.
Multi-Site Integration & Scalability
Despite managing validation across multiple contract manufacturing sites with different quality systems and operational approaches, the framework successfully created cohesive approach demonstrating system-level process control. The coordination ensured all sites worked toward consistent standards while respecting their individual operational contexts.
The established framework provided reference for replicating processes as manufacturing expanded or new sites were added—enabling geographic expansion and capacity growth without requiring complete revalidation of the strategic approach.
Risk Mitigation & Commercial Readiness
The investment in comprehensive validation strategy framework prevented costly problems emerging from improperly qualified manufacturing processes including product quality issues requiring recalls, manufacturing delays from process failures, regulatory compliance gaps, and customer complaints from inconsistent products.
By establishing strategic framework for proving process control, validation planning protected business objectives and brand reputation. The company could proceed to commercial launch with confidence that manufacturing capability had been systematically verified.
Note: MKA established the validation strategy and framework during the program management engagement. The company transitioned validation protocol development and execution to internal quality teams and validation specialists after MKA’s engagement concluded in March 2022. The strategic framework provided clear roadmap enabling the company to complete validation activities with appropriate specialists.
