The XYZ of data safety

摘要

Safety Management has matured from simple process based arguments to become hazard focused and proactive. The adoption of Goal Structuring Notation and 'product line' safety arguments means that products comprise multiple constituents in several axis. Data is now ubiquitous in the development, operation and assurance of products. This paper therefore explores data safety in the form of a three-axis model. A process that uses this model is discussed. Model validation is by reference to existing safety and assurance models and case studies.
