I’ve skipped heaps – the ‘doing’ part of the abstraction hierarchy, but their descriptions of the problem and the discussion had some gold. For context: ·         Procedural issues have been linked in a number of major accidents… Continue reading Analyzing Procedure Performance using Abstraction Hierarchy: Implications of Designing Procedures for High-risk Process Operations
