How ergonomics can fatten the bottom line

It has been demonstrated in numerous industries that “work” designed on sound ergonomic principles results in substantial business benefits, including increases in productivity, improved product quality, decreased rework, improved efficiency and less wasted time.
In today's business world, companies are focused on producing more with less while increasing profit margins. Ask any site superintendent what they are accountable for and you will hear terms like “on-time delivery,” “quality,” “reduced scrap” and “improved profit margins.” Ergonomics is not even in their vocabulary and it seems that injuries are assumed to be a cost of doing business.
In the construction industry, you may hear, “Ergonomics won't work in construction because the work is too physical and can't be changed.” With the continued focus on increasing profits and reducing costs, the value of ergonomics needs to be demonstrated in language that management understands — MONEY.
So we need to ask, “What is the value of our ergonomic effort and can we demonstrate that value in dollars?”
Combining ergonomics with production philosophies such as “Five S,” “Lean,” and “Six Sigma” creates a winning combination to improve efficiency and business performance. These high-level initiatives began in manufacturing but are now being used in shipyards, health care, forest products and other industries. They share the common goals of “improvement” and “reducing waste,” where waste is defined as any human activity that absorbs resources but does not add value.
Good planning and work organization are key elements to reducing waste. On a construction site, how often are materials delivered far from where they are needed, requiring them to be transported either mechanically or manually across the site? Time is wasted, unnecessary machinery may be used, and the extra manual material handling may result in an injury.
These are all examples of waste.
Concrete slump provides another example. If the slump is unnecessarily low, it will be more difficult to spread, creating unnecessary physical work for laborers. The spreading process may also take longer. Planning for the appropriate slump is essential to reducing excess physical work.
Successful integration of ergonomics and “lean” in an industry that shares some of the heavy physical challenges faced in construction is in the ship building and repair industry. At Todd Pacific Shipyards, workers hang coils of hose on a portable pallet-mounted “tre” to make them quicker and easier to reach.
Todd Pacific's improvement in business performance may have an application in construction as well.
For ergonomics to be considered a business necessity, its value must be demonstrated in terms that business leaders understand. Focusing on how ergonomics can impact quality, cost, productivity, safety and worker morale helps to leverage ergonomics into a position of higher visibility.
People are the most valuable part of any business. Fitting “work” to the people that do it is a must for world class businesses.
