Products and services delivered to clients are subject to review and approval by our technical supervisory board composed of senior industry managers and research/academia experts.

Members have all more than 25 years broad industry experience and robust competence in their own professional discipline.

The technical supervisory board acts independently and autonomously and ensures that GPCI delivers best of class products and services to its clients.

Technical supervisory board members may be also involved at early project framing stages to ensure adequate scoping and are available for regular or ad hoc expert advice up to board room level.
