Quality and Human Factors in Consumer Products

quality and human factors

Manufacturers of consumer products should incorporate human factors into their Quality Management Systems (QMS).  Because human factors are directly connected to product safety, it is important that it be considered in all phases of product development and life cycle.  The Division of Human Factors, U.S. Consumer Product Safety and Health Canada’s Consumer and Hazardous Products Safety Directorate jointly released Guidance on the Application of Human Factors to Consumer Products in February 2020.  This was released to help consumer product manufacturers integrate human factors into their product development process.

What is Human Factors?

Human Factors is a discipline that studies of relationships between humans and elements of a system or product.  The discipline is comprised of engineering and test and evaluation practices.  User Experience and Usability are associated fields that evaluate human/product interfaces.  Design methods that consider human characteristics, capabilities and limitations create safe and effective products.  The benefits of including human factors into product design include:

  • Improved usability and acceptance.
  • Increased safety.
  • Reduced lifecycle cost and risk.
  • Reduced support and help desk costs.

Quality Management and Human Factors

Human Factors engagement is not limited to product design.  It also applies to testing, validation, and evaluation during the production and post-production phases of a product lifecycle.  Because these activities are identifiable and create viable metrics for assessing product effectiveness and safety, they can be implemented into a QMS’s policies and procedures.  Risk identification and mitigation for product safety should:

  • Identify potential cost, schedule, design, safety, and performance risks that result from design aspects of human-system integration;
  • Quantify these risks and their impacts on cost, schedule, and performance;
  • Define and evaluate sensitivity of potential risks as related to the human interface;
  • Identify alternative solutions to human factors problems and define the associated risks of each alternative;
  • Document the identified risks, their impact on the product, and the mitigation action(s) taken;
  • Take actions to avoid, minimize, control, or accept each human factors risk; and
  • Ensure that human performance risks are included in the overall product’s risk-management process.
