Why Should Human Factors and Ergonomics Initiatives Be Important to Your Organization?


Why Should Human Factors and Ergonomics Initiatives Be Important to Your Organization?

In the business world, benefits are often judged by their return on investment (ROI) – the ratio of the profit gained or lost relative to the cost of achieving the profit. According to Wilson and Rosenbaum (2005), there are three categories of return on investment (ROI): internal; external; and social. Internal ROI refers to benefits that save the organization money when developing products or services.

This can take the form of decreased development costs, preventing the need for redesign, and reduced time in getting the product to market. External ROI refers to benefits that increase the profitability of products or services by making them better for the customer. This can take the form of increased sales, increased market share, decreased customer support and service costs, decreased return rate, and improved user experience.

It should be noted that Internal ROI typically must be demonstrated before External ROI can be realized. Social ROI refers to the perception that human factors / ergonomics initiatives are beneficial and can affect both Internal and External ROI. Internal Social ROI includes the perception of stakeholders that a given initiative provides a benefit, which in turn, increases management “buy in.” External Social ROI consists of customer’s positive perceptions of the organization due to past satisfactory experiences and demonstrated trustworthiness, which leads to improved branding and strengthened corporate image.

A common way to determine the benefit of a given human factors / ergonomics initiative is by performing a cost-benefit analysis. The results of a cost-benefit analysis can guide where an organization can best invest their financial resources, thus maximizing their return on investment (ROI).

There is a growing body of literature that demonstrates a positive return on investment (ROI) for implementing human factors / ergonomics initiatives. Case studies have demonstrated the benefits for many technologies, processes, and industries, including:

  • Websites (Bias & Mayhew, 2005);
  • Software (Bias & Mayhew, 2005);
  • Computers (Beevis, 2003; Nielson, 1993);
  • Intranets (Kerr, et al., 2008);
  • Electronics (Hendrick, 1996; Sen & Yeow, 2003);
  • Office ergonomics (Goggins, et al., 2008);
  • Workplace ergonomics / manual material handling (Hendrick, 1996; Lahiri, et al., 2005; Maudgalya, et al., 2008; Rodrigues, 2001);
  • Industrial production lines (Stanton & Baber, 2003);
  • Forestry (Hendrick, 1996);
  • Automotive (Stanton & Baber, 2003);
  • Aircraft (Hendrick, 1996);
  • Petroleum (Hendrick, 1996);
  • Healthcare (Goggins, et al., 2008);
  • Nuclear (Kirwan, 2003) and electrical power plants (Seeley & Marklin, 2003).

Specific benefits for human factors / ergonomics initiatives include:

  • Assembly job redesign: 10.76% first year ROI & 30.10% subsequent year ROI (Lyon, 1997)
  • Workstation redesign: 15% increase in productivity (Hendrick, 2003)
  • Robotic case palletizer: 17% ROI over a 10 year period (Rodrigues, 2001)
  • Log truck redesign: $6,900 investment & $65,000 return = 1:9.4 first year cost-benefit ratio (Hendrick, 2008)
  • Electric utility tool replacement: $300,000 capital investment paid back in 4 months (Seeley & Marklin, 2003)
  • Motherboard redesign: $581,495/year factory savings & $142,105/year customer savings (Sen & Yeow, 2003)
  • Computer usability: 200% – 500% return on a 6% budget investment (Nielson, 1993)

These benefits arise by increasing and decreasing cost related aspects of the development, manufacturing, distribution, sales and support activities. These increases and decreases include those shown below.

Increased Decreased
  • Ease of use
  • Ease of learning
  • Satisfaction, trust, & loyalty
  • Repeat purchases
  • Purchase recommendation
  • Safety & health
  • Productivity & work quality
  • Satisfaction & commitment
  • Sales & market share
  • Stock value
  • Brand recognition

 

  • Accidents, injuries & illnesses
  • Lost workdays
  • Error rates
  • Training time
  • Absenteeism & turnover
  • Development costs
  • Need for redesign & recall
  • Support & service costs
  • Labor costs
  • Equipment damage
  • Maintenance costs
  • Insurance rates
