When accidents happen, it is common to blame the end-users, the pilots, the drivers, the controllers, those who are at the front line of the operation. But accident investigators often admit that there were flaws in the design of the ICT system, engineered device, or business procedure. This book provides a research-based investigation into the design process, pointing out how and where errors creep in, and offers practical advice on strategies to remove potential hazards from design projects in the future. Real life examples are used to demonstrate the points being made.
