ABSTRACT
This chapter considers the conceptual and operational toolset and mindset needed to develop well-founded trust between different parties with different perspectives on complex concerns needing formal planning. It addresses potential catastrophes in an enlightened manner at a high level of clarity. The top-down perspective the board needed had to see the pyramid built by the safety and security team from the top. The bottom-up building of that pyramid by the safety and security team needed to understand the architecture of the whole structure needed by the board. Oscar began his workshop by indicating that the basic foundations of Northern European Railways (NER) approaches to safety and security had to change radically. The starting point for an NER approach to As low as reasonably practicable had to be a ‘holistic base-case model set’ which captured their railway system’s safety and security status with strategic clarity.
