Human factors: Procedures

Why is good procedure design important?

Procedures, including method statements, work instructions, permits to work etc, are agreed safe ways of doing things. They usually consist of instructions and related information needed to help carry out tasks safely. Procedures may include step-by-step instructions, checklists, decision aids, diagrams, flow-charts and other types of job aids

Problems with procedures are linked to numerous incidents and frequently cited as one of the causes of major accidents. The inadequate management of procedures have not only contributed to disasters such as Bhopal, Piper Alpha and Clapham Junction, but also to fatalities, personal injuries and ill health.  The main causes are too much reliance placed on procedures to control risk, a failure to follow safe working procedures or the use of inadequate procedures.

Operating procedures may not be the best way of controlling hazards, at least not as the sole defence against human error.
