What are human factors in the workplace?

Human factors is the scientific discipline concerned with how people interact with their work environment. It examines the complex relationships between individuals and the job, organisational, and environmental factors that influence their behaviour at work. The goal of considering human factors is to design work systems that optimise human well-being and overall system performance, leading to improved health, safety, and productivity. 

Key categories of human factors

There are three main areas of human factors in the workplace: 

• Individual factors

  • Physical: Aspects like an individual's body size, strength, health, fatigue, and physical abilities.

  • Psychological: An employee's personality, attitudes, motivation, perception of risk, and mental abilities.

  • Training and experience: The skills and knowledge an individual brings to a task can influence their performance.

    
    

• Job factors

  • Task design: The nature of the task itself, including its complexity, workload, and mental demands.

  • Equipment and tools: The design and usability of the equipment employees use.

  • Procedures: The role of clear, up-to-date, and well-designed procedures.

  • Workload: The physical and mental demands of the job, including pace and working hours.

    
    

• Organisational factors

  • Work patterns: Issues like shift work, staffing levels, and work breaks can significantly affect human performance.

  • Culture: The workplace's safety culture, including the attitudes and behaviors that are considered normal.

  • Communication: How information is transmitted between individuals and teams.

  • Leadership: The messages and cues that managers and supervisors send about safety priorities.

  • Resources: The availability of adequate resources such as personnel, time, and tools. 

    
    

The importance of human factors

Ignoring these factors can lead to unintended consequences that affect safety, productivity, and employee morale. By proactively addressing human factors, organizations can achieve multiple benefits: 

• Reduced human error: Human factors analysis helps move beyond simply blaming "human error" by identifying the underlying systemic weaknesses that set people up to fail.

• Improved safety: By designing jobs and equipment to account for human strengths and limitations, organizations can create a safer work environment and prevent accidents and injuries.

• Increased productivity: When the work environment and tasks are designed to align with human capabilities, employees can perform more efficiently and effectively.

• Higher job satisfaction: A well-designed workplace that considers employees' needs can lead to better morale, increased engagement, and reduced absenteeism.

• Creation of a positive safety culture: Engaging employees and fostering open communication about safety concerns helps build a strong safety culture from the ground up. 

Business benefits

Managing human failures is essential to prevent major accidents, occupational accidents and ill health, all of which can cost businesses money, reputation and potentially their continued existence.

Successful businesses achieve high productivity and quality while ensuring health and safety. Good technology combined with the best work systems can help to achieve these goals. The best work systems are based on having a skilled workforce, with well-designed jobs that are appropriate to individuals' abilities.

The influence of biological, psychological and organisational factors on an individual at work can affect their health and safety, but it also affects their efficiency and productivity.
