OUR SERVICES
from early concept through to in-service operationsWe bring human factors into the design and operation of complex systems.
Our work is always targeted, always evidence-based, and always shaped by the operational realities of the environments we work in.
HUMAN FACTORS INTEGRATION (HFI)
Human Factors Integration is the systematic process of ensuring that human capabilities, limitations and behaviours are considered and addressed throughout the design, procurement, introduction and operation of complex systems. In short, it’s about making sure the humans in your system are set up for success.
We deliver HFI across the full project lifecycle — from early concept and feasibility through to commissioning, in-service operation and change management.
Our HFI services include:
Development and management of Human Factors Integration Plans (HFIPs)
Human Factors User Requirement (HFUR) identification and derivation
Human Factors analysis, assessment and reporting across engineering, operational and business systems
Task analysis and human error analysis
HF oversight and governance activities
Workstation, control room and rolling stock design support
Station design, accessibility and wayfinding
Workshop facilitation and end user consultation
HF incident investigation
HF assurance reporting to support regulatory and accreditation requirements under the Rail Safety National Law (RSNL)
HFI to support change management, accreditation applications, variations and notifications of change
Whether you are introducing a new fleet, upgrading infrastructure, modifying existing equipment or navigating a regulatory change process, we provide the Human Factors expertise to manage risk and support defensible, evidence-based decision making.
FATIGUE RISK MANAGEMENT
Fatigue in safety-critical operations is a systemic risk and one that demands a structured, evidence-based approach to identify, assess and manage. Heilsa delivers fatigue risk management services that are practical, proportionate and aligned with industry standards and regulatory expectations.
Our fatigue risk management services include:
Technical roster reviews and fatigue risk assessments
Fatigue Risk Management System (FRMS) development, review and improvement
Fatigue and workload studies, including in-cab and in-field assessments
Risk-based rostering and scheduling tool development
Workload analysis across operational roles and shift types
Fatigue risk management audits
Integration of fatigue risk outcomes into broader safety management systems
We understand the operational and commercial pressures that shape roster design in the transport industry. Our work is designed to support sustainable, risk-managed outcomes, not to add administrative burden.
OCCUPATIONAL HEALTH & ERGONOMICS
Good ergonomics is the foundation of safe, effective and sustainable work. Where people interact with equipment, infrastructure, tools and workspaces, there is an opportunity to either increase or reduce risk. We bring structured health and ergonomic assessment and design support to transport and industrial environments.
Our services include:
Physical ergonomic assessments of workstations, cabs, control rooms and maintenance environments
Participative ergonomics programs, working directly with frontline workers to identify and resolve risks
Manual handling risk assessment and design improvement
Job dictionary and task library development
Health risk profiling and rail health risk assessments
Psychosocial hazard analysis
SAFETY INVESTIGATIONS
Safety incidents rarely result from a single action or failure. Effective investigations look beyond immediate actions to understand the operational, organisational and systemic factors that contributed to the event. Heilsa provides independent, systems-focused investigations, as well as specialist support to internal investigations teams. Our approach is evidence-based, no-blame and focused on identifying active and latent failures, human performance influences and broader systemic safety issues.
Our services include:
Independent external investigations and reviews
Human factors support to internal investigation teams
Systems-based accident and incident analysis
Human error and error antecedent analysis
Application of recognised investigation methods, including iCAM, 5 Whys and PEEPO
Cognitive interviewing and evidence-gathering techniques
Multidisciplinary support from human factors and experienced rail safety investigators
Independent review of investigation findings and recommendations
Coaching and training in interviewing techniques for internal investigators
Our focus is on providing proportionate, defensible investigations that support organisational learning and meaningful safety improvement.
