John is a Security Management Systems (SeMS) subject matter expert, and was responsible at the UK CAA for developing the UK SeMS framework published jointly by government and the CAA.  As the CAA’s Aviation Security Strategy Lead and SeMS subject matter expert, John worked with many industry stakeholders and guided the first two pathfinder organisations to develop their SeMS to achieve a successful regulatory assessment.

Experienced in guiding the design and implementation of effective strategic change in public and private sectors to improve operational effectiveness, John has been a lead designer of numerous governance, risk and compliance systems.  He is adept at unifying strategic vision with its practical delivery to drive business change and align objectives with business requirements; innovating practical solutions to strategic and operational challenges, removing obstacles to change and achieving strategic goals and training / mentoring multi-disciplined teams to embed fresh working practices and behaviours which drive performance improvements.  

John is a qualified project, programme and risk manager, (PRINCE2, MSP, MoR) and holds a masters degree in Physics from Oxford University. 

Relevant achievements and accolades

On completion of his assignment at the CAA, John recognised the need to continue the promotion of SeMS worldwide and founded SeMSnet, a group for security managers and related experts to share best security and risk management practice. In 3 years, SeMSnet has grown to 1300+ members worldwide and continues to debate the key issues in aviation security management.  

Prior to SeMSnet, John had two key roles at the CAA. Originally engaged to develop the safety regulation strategy, John led this programme to create the strategy and implementation blueprint for the CAA’s Performance Based Regulation which is being implemented across all divisions of the CAA’s safety group and has been adopted by a growing number of regulated entities.  On the basis of that success, John was assigned to develop the Security Regulation Strategy, and on publication of the strategy as part of the CAA’s strategic plan, he quickly allied with the UK government’s aviation team to implement that strategy by driving development of the Framework for SeMS, authoring much of the document himself, and developing the surrounding methodology and practices.

John has consistently demonstrated his value to clients, receiving testimonials such as: · “John's guidance and support in helping me develop a security management system at the airport was invaluable. His advice was always practical and he very quickly grasped the issues.”

“John has continuously demonstrated his almost unique ability to get inside his client's head, win them over and then help them deal with complex system, organisational and cultural challenges.” · “He is a visionary, problem solver and has a great capability to convert the vision and deliver a practical workable solution. He used all of these skills on a major change programme working alongside the stakeholders and delivering through leadership and mentoring.”
