It’s people that daily interact with systems, tools and processes across all level of organizations.

Human performance encompasses the way teams adapt to complex, dynamic environments, often navigating challenges and dilemmas to successfully carry out assigned tasks and activities.

The goal of focusing on human performance is to create error-tolerant systems that are based around the capabilities, characteristics, and needs of people.

Why Human performance matters

• Because error is normal—and systems must be ready for it
• Because blaming people prevents learning and improvement
• Because safer, more resilient operations depend on how work is actually done

What Human performance means in practice

• Shifting focus from individual failure to system design
• Understanding the context behind everyday decisions
• Creating conditions where people can succeed

Principle 1: Error is Normal

Human Performance is grounded in the recognition that error is an inherent aspect of human nature. Since eliminating errors entirely is often impractical, they must be planned for by implementing strategies that anticipate them and minimize their impact, with systems strengthened to withstand and recover from mistakes.

Principle 2: Blame Fixes Nothing

Blame fosters a culture of fear, discouraging people from speaking up, leading to concealed mistakes and missed opportunities for learning, eventually halting improvement journeys. HP promotes investigating the circumstances and factors leading up to an event with the aim of assessing the systemic factors which may have led to errors.

Principle 3: Context Drives Behaviour

Systems, processes, equipment, and culture collectively influence the decisions individuals make, the actions they take, and – in the long term – the social norms that emerge. Understanding the context of work enables better risk management, design, and execution of tasks.

Principle 4: Learning is Vital

Human Performance depends on an organization’s commitment to continuously and deliberately learn and improve. Rather than waiting for failures to trigger an analysis, everyday work should be proactively learned from, whether successful or not.

Principle 5: How Leaders (You) Respond Matters

How the leaders of an organization respond to both successes and failures is crucial to building a strong and effective culture of a learning organization. A thoughtful and deliberate leadership’s response to human performance shapes how the organization perceives error, context, blame, and learning.

The five Human Performance principles promote a culture where learning is prioritised, and systemic factors are addressed. By embedding these principles into decision-making and leadership behaviours, organisations focus on building resilient, error-tolerant systems.

Alongside the principles are several foundational concepts that explain how HP can be integrated into real-world operations. Together, the principles and fundamentals provide a comprehensive framework for improving safety, and creating conditions where people can succeed under varying circumstances.
