CSV Expertise: Ensuring compliance, quality, and patient safety
In the Life Sciences industry, regulatory compliance is not just a requirement, it is a safeguard for patient safety, product reliability, and public trust. Every medicinal product, from early development to post-marketing surveillance, must meet stringent international standards to demonstrate that all data, processes, and outcomes are accurate and dependable.
Among the disciplines that ensure these expectations are met, Computer System Validation (CSV) plays a decisive role. CSV verifies that the digital systems used throughout the product lifecycle operate as intended and comply with regulations such as FDA, EMA, MHRA, Japan PMDA, China FDA, OECD, and GxP guidelines.
From laboratory information systems to clinical trial tracking tool, pharmacovigilance platforms and manufacturing, CSV ensures that every software involved in drug development and production delivers reliable data, documented traceability and safety assurance. This includes adherence to data integrity principles such as ALCOA+, which are critical for maintaining trust in electronic records and ensuring compliance throughout all processes and across the entire data lifecycle.
A typical CSV project follows a structured and controlled lifecycle,
including:
- Comprehensive planning with stakeholders
- Implementation and documentation of system compliance
- Gap analysis and corrective actions
- Final validation reporting
At ALTEN Belgium, this process is carried out through a rigorous and collaborative framework, supported by strong communication, continuous alignment with stakeholders, and a commitment to delivering compliant, robust, and future-proof systems.
To shed light on the day-to-day reality of this profession, we spoke with Mouna Guessous, CSV Engineer, who contributes to both delivery and team development.
What are the main responsibilities of a CSV consultant, and what technical skills or personal qualities are essential for success in this role?
Mouna: I provide end-to-end support on CSV projects, from initial planning through to the final validation document. I also provide ongoing support for systems already in place as they evolve and require maintenance. In addition, I act as Stream Leader, training and supporting junior consultants on our platform.
To succeed, you need a strong sense of rigour, a critical eye, and a good understanding of validation processes and tools. But personal qualities matter just as much: resilience, attentiveness, and a collaborative mindset. Building strong relationships with stakeholders is key.
How would you describe the atmosphere and dynamic within your team of ALTEN consultants? What do you think is your greatest collective strength?
Mouna: We have an excellent team dynamic. We work in an open space, which encourages constant interaction. Whenever someone has a question, they can rely on others for support. We also share social moments, like lunches and coffee breaks.
Even on remote working days, we stay connected through regular chats and virtual touchpoints to keep collaboration alive.
Our greatest strength? Collaboration and mutual support.
What motivates you most in your job, and what makes you proud of your career at ALTEN?
Mouna: What I love most is the variety of projects. Each new assignment brings something different, whether technically or in terms of human interaction. You never get bored! I’m proud to contribute to projects that have a real impact on product quality and patient safety.
If you had to give one piece of advice to someone who wants to start a career in CSV, what would it be?
Mouna: Understand the purpose behind what you do. Knowing why we validate these systems makes the job truly engaging. Be curious, rigorous, embrace continuous learning and enjoy working as part of a team.
At ALTEN Belgium, CSV is more than a compliance requirement, it is a driver of product reliability, patient safety, and operational excellence.
