High reliability

"High reliability organizations are organizations that operate in complex, high-hazard domains for extended periods without serious accidents or catastrophic failures. The concept of high reliability is attractive for health care, due to the complexity of operations and the risk of significant and even potentially catastrophic consequences when failures occur in health care."

Failure mode and effect analysis (FMEA)

"Failure mode and effect analysis (FMEA) is a common approach to prospectively determine error risk within a particular process. FMEA begins by identifying all the steps that must be taken for a given process to occur ("process mapping") and then how each step can go wrong (i.e., failure modes), the probability that each error will be detected before causing harm, and the impact of the error if it actually occurs. The estimated likelihood of a particular process failure, the chance of detecting such failure, and its impact are combined numerically to produce a criticality index, which provides a rough estimate of the magnitude of hazard posed by each step in a high-risk process. Steps ranked at the top (those with the highest criticality indices) should be prioritized for error proofing."

Human Factors Engineering

"Human factors engineering is...the discipline that takes into account human strengths and limitations in the design of interactive systems that involve people, tools and technology, and work environments to ensure safety, effectiveness, and ease of use."
