A - Z Glossary Terms:
Adaptation
The ability of workers and systems to adjust to unexpected challenges and changing conditions to maintain safety and performance. Adaptation is essential in dynamic and complex environments.
Attention Activators
A tool, technique, or prompt designed to quickly capture and focus workers’ attention on critical safety information or tasks.
Auditing to the black line
A method of assessing work as it is actually performed (the blue line) against documented procedures or expectations (the black line), often used to penalize non-compliance, but ideally used to identify gaps and better understand operational realities.
Bias
The preconceptions or predispositions that individuals bring to their understanding and decision-making processes.
Example: Hindsight Bias.
Black line
The plan for completing work ("Work as Imagined"), often unable to account for real-world variability.
Black Line Blue Line
A sense-making model that contrasts the ideal, imagined, or documented work process (black line) with how work is performed in reality (blue line).
Blame
Assigning fault, which can prevent learning and improvement by shutting down curiosity and creating fear and defensiveness.
Blue line
The actual path taken to complete work ("Work as Done"), adapting to real-world challenges.
Brittle
A system or process that lacks resilience, offering little capacity to absorb or adapt to variability or unexpected conditions. Brittle systems are prone to failure under stress.
Complex adaptive system
A dynamic network of interdependent variables that continuously adapt and evolve to changing environments. It often involves human interaction and requires ongoing adjustment to manage variability and change. Examples include organizations and industrial processes.
Complexity
The interaction of numerous variables and dynamic conditions within a system, making outcomes unpredictable and emergent.
Complexity Science
The study of systems with many connected parts that create unexpected behaviors and patterns that can’t be understood just by looking at the parts alone.
Compliance
Adherence to rules, regulations, and standards. In HOP, compliance is considered necessary but not sufficient to ensure safety or operational excellence. Synonym: autopilot
Compliance mentality
A mindset that prioritizes following rules and procedures above all else—often at the expense of learning, adaptability, or understanding real work. It assumes that rule-following alone will ensure safety and success.
Context
The specific conditions and circumstances surrounding an event or situation, including both the physical environment and the less tangible factors that influence how work is done and decisions are made.
Coupling of variability
The interaction and amplification of different sources of variability within a system.
Cross-thread
The misalignment of threaded parts during fastening that compromises the connection.
Disciplinary action
Measures imposed on individuals who violate established rules or expectations. (From a HOP perspective, disciplinary action should be applied fairly and proportionately, taking into account underlying system factors that might influence behavior.)
Discipline
See: Disciplinary action
Error
An unintended action often leading to an unintended result.
Event
An occurrence with potential safety, operational, or system implications.
F.R. clothing
PPE specifically for fire protection.
Flight plan
A detailed sequence of maneuvers that outlines the load’s trajectory, rigging configuration, and operational steps to ensure safe, efficient, and coordinated lifting and placement of heavy loads.
Fox in the hen house
(idiom) Bob uses this term to describe employee sentiment about inspectors and auditors when they come into the workplace looking to identify and correct non-compliance (without understanding context).
Fundamental Attribution Error
A bias where we think others act a certain way because of their character or personality (a person problem), not their situation (a system problem).
Hawthorne Effect
The tendency for individuals to change their behavior simply because they are aware that they are being observed.
Hollnagel, Erik
A renowned Danish researcher and thought leader in safety science and resilience engineering, best known for developing the Safety-II approach and advancing our understanding of human and organizational performance.
HOP (Human and Organizational Performance)
An operating philosophy that focuses on understanding how humans interact with their work environment and systems.
Leader standard work
A structured set of daily routines and responsibilities that leaders follow to ensure operational consistency, maintain safety standards, and drive continuous improvement through regular performance checks and team engagement.
LEAN
An industrial philosophy and methodology focused on continuously eliminating waste, optimizing processes, and enhancing efficiency to maximize value and quality in production and operations.
Learning session
One session of a learning team (see: Learning team)
Learning Team
A facilitated conversation with those who perform the work to understand how the work actually gets done. The goal is to learn first, then define the problems, and lastly to come up with ways to make things better. It is based on elevating the voice of the worker.
Master of the Blue Line
Frontline workers who, operating within complex adaptive systems, possess intimate day-to-day operational knowledge around procedural adherence and necessary adaptations in real-world situations.
Mechanical system
A system that operates in a predictable, linear, and controllable way.
Mistake
An intended action leading to an un-intended outcome.
Near miss
A potential perfect storm where a worker adapted and changed before the negative outcome came about, or an element of luck reduced the severity of the outcome.
Opaque system
A system in which internal processes and decision-making are not readily visible or understandable, making troubleshooting, risk assessment, and optimization more challenging.
Operational challenge
The difficulties encountered during the execution of operational tasks or processes
Operational fidelity
The degree to which a rule or procedure is practical, makes sense for the end user, and aligns with how work is actually done (Blue Line); the rules and procedures make sense in a day to day operation
Operational learning
The process of acquiring, adapting, and applying knowledge and insights gained from operational experiences to improve performance, enhance safety, and optimize processes by learning from both successes and failures, and continuously refining practices based on real-world experience and feedback
Operational learning team
A small group of workers and leaders who come together to understand how work really happens, share insights from experience, and identify ways to improve safety, performance, and systems by learning from both challenges and successes.
Operational upset
An unexpected or disruptive event that deviates from normal operational conditions and can affect efficiency, or effectiveness of processes.
Operator
Individuals who executes work on specific processes or machines.
Ordered system
A structured, predictable environment where operations follow clear, repeatable rules or laws (Like the laws of physics), and failures are typically straightforward with identifiable, single causes that experts can diagnose and fix.
Perfect storm
A swirl of many conditions coming together at the same time.
Person problem
An issue that follows the person around, regardless of team or department; if the person is replaced the problem goes away.
