3. 1. Ergonomics is not simply a lay person’s “common sense”; professional expertise is required. Ergonomics programs: Invariably, the more than 30 poor ones that I have examined have not been staffed by professional ergonomists.
Ergonomic design. “Common sense” design that does not include input and approval by a professional ergonomist often induces human error.
Sometimes just frustrating and a nuisance,
But sometimes has disastrous results!
4. 1. Ergonomics is not simply a lay person’s “common sense”; professional expertise is required. A Disastrous “common sense” example experienced by myself
Development of a new aircraft altimeter
Replaced old 3-pointer altimeter in F-86D fighter aircraft with a
2-pointer with direct odometer type readout to replace the 3rd pointer.
Indication Old Altimeter New Altimeter
10,000 ft . Short pointer Direct readout
1,000 ft. Medium pointer Medium pointer
100 ft. Long pointer Long pointer
5. 2. Good ergonomics projects typically give a direct cost benefit of from 1 to 2, to 1 to 10+, with a typical pay-back period of 6 to 24 months. Good ergonomics can be defined as appropriately applied ergonomics technology that also is cost effective.
In part, lesson 2 above is based on my review of 24 documented widely differing good ergonomics projects (see Hendrick, 1997. Good ergonomics is good economics. Available for downloading in pdf format at no cost at http://hfes.org).
Many other examples have been reported to me by ergonomists around the world.
6. 3. Life cycle ergonomics cost-benefit savings can be 1-50, or greater. Personal example: C141 Aircraft *
Documented initial fleet cost savings of $5 million from a $500,000 ergonomics program – a one to ten direct cost-benefit ratio.
Conservatively, the true cost-benefit savings over the 35+ year life cycle of the aircraft fleet has been greater than 1 to 50.
*Hendrick, H. W. (1997). Good ergonomics is good economics. Santa Monica, CA: Human Factors and Ergonomics Society.
7. 4. Effective ergonomics programs on large system development projects take only 1% of the engineering design budget E. Jones & H. Hendrick (1980), based on a study of 10 major system development Projects having an effective professional ergonomics program.
Auburn Engineers study (D. Alexander, 1999).
8. 5. The earlier ergonomics is applied in design, the cheaper the cost and greater the benefit Table 1. The costs of using ergonomics in design.*
___________________________________________________
Stage of Development Portion of Engineering Budget
___________________________________________________
Early Design 1 % to 2.0%
Blueprint 1% to 3.0%
Construction 2% to 6.5%
Commissioning 4% to 10.5%
Normal Operations 5% to 12+ %
_____________________________________________________
*Auburn Engineers, Inc. Reported by Dave Alexander
at the April 2002 DoD Ergonomics Conference.
9. 5. The earlier ergonomics is applied in design, the cheaper the cost and greater the benefit (continued). Software design. Conservatively, the cost of catching and solving ergonomic usability design problems early in the software design process costs about 1/4th of what the same changes made late would cost.*
*See Mantei, M. M., and Teorey, T. J. (1988). Cost/benefit analysis for incorporating human factors in the software life cycle. Communications of the ACM, 31(4). 428-439.
10. 6. The language of business is money!
Managers have to justify any expenditure in terms of the cost- benefit ratio: How the project will affect the bottom line.
Must express ergonomic project proposals in financial terms.
11. 7. Costs and benefits of ergonomics projects must be measured. Costs
Personnel, training, equipment, materials, reduced productivity, and overhead.
Benefits
Personnel savings: Less lost time, less training, lower skill levels required, increased output per person, fewer people required.
Material savings: Reduced scrap, fewer rejects, fewer parts, less expensive or fewer materials or equipment.
Reduced overhead: Resulting from direct cost savings.
12. 7. costs and benefits of ergonomics projects must be measured. Sources of information
Much of the cost and pricing information is available through either your human resources or accounting departments, including overhead percentage.
Some benefits can be directly calculated.
Projected benefits which cannot be directly calculated can be gained through the literature and looking at similar projects in other organizations.
13. 7. Costs and benefits of ergonomics projects must be measured. Less Tangible Benefits
Increased Employee Satisfaction and Commitment : Leads to “good citizenship” behavior. Can reduce grievances, improve productivity, and improve inter- and intra-group relations – all of which can have a positive financial impact.
Improved Organizational Image: Can result in less governmental scrutiny & better community relations – all of which can have a positive financial impact.
These benefits are the “icing on the cake”
14. 7. Costs and benefits of ergonomics projects must be measured. Example: Tractor Forwarding Units, South African Forestry Industry
Original Unit: Poor operator seating and visibility
Human Factors is the study of the physical and mental characteristics, capabilities and limitations of human beings AND the design of tools, equipment and systems that take these human factors into account.
Human Factors is primarily a science related to design--the design of systems that take certain inputs and produce desired outputs.
However, we realize that humans are part of this system and so both the strengths as well as the weaknesses.
Systems where humans and machine work together, which is mostly what we deal with, are called human-machine systems.Human Factors is the study of the physical and mental characteristics, capabilities and limitations of human beings AND the design of tools, equipment and systems that take these human factors into account.

19. 7. Costs and benefits of ergonomics projects must be measured. Conducted macroergonomic analysis of operational work system.
Results
Original design: Kits had many parts that would never be removed from the aircraft.
Redesigned kits to only include items that would not be left in aircraft; the rest of the components were built in.
20. 7. Costs and Benefits of Ergonomics Projects Must be Measured. Personal Example: C-141 Aircraft
Saved $2.5 million in original price.
Kits smaller, lighter, easier to store and could be installed faster with fewer people.
Saved storage cost and reduced personnel requirements.
Built in parts were fewer and lighter in weight.
Reduced actual aircraft operational weight and related fuel costs for entire fleet of over 200 aircraft over 35+ year period.
21. 7. Costs and benefits of ergonomics projects must be measured. Personal Example: C-141 Aircraft
Good example of what ergonomics can do when integrated with engineering design early in the development program.

Results
- Error rate dropped from 35 per 100 to
less than 1 in 1,000.
- Saved $2 million in first two years.
27. 9. Management awareness is critical to management commitment (which is critical for an effective ergonomics program or project). Study by Ed Jones and myself of DoD Major System Development Programs.
- Evaluated major DoD system development programs over a 10-year period in terms of whether they had a good or poor ergonomics development effort.
- Found those with a poor effort had major problems when they became operational.
- Looked for what made the difference between those with a good effort vs. those with a poor effort.
28. 9. management awareness is critical to management commitment (continued). Study by Ed Jones and myself of DoD Major System Development Programs.
Results:
- Major discriminating factor was the level of ergonomics
awareness of the program director.
- Aware directors appreciated value added of ergonomics -- and so allocated scarce personnel resources and funding to ergonomics. Those lacking knowledge of ergonomics did not .
29. 9. Management awareness is critical to management commitment (continued). Study by Ed Jones and myself of DoD Major System Development Programs.
Lesson
Establishing rapport with key managers and raising their consciousness about ergonomics is essential to your long-term success.
This often takes time and persistence!
Personal example: A major hotel chain.
30. 9. Management awareness is critical to management commitment (continued).
Personal Example: A major hotel chain
Initial entry: Assessing hotel managers and key staff.
Established rapport with key corporate Vice Presidents (Human Resources and Labor Relations; Operations).
Raised their awareness of HF/E over a two year period.
Then implemented behavioral modeling training for all supervisors and a quality circle program with strong ergonomics and safety orientation.
31. 9. Management awareness is critical to management commitment (continued). Personal example: A major hotel chain
Results (after two years)
- The flagship hotel’s customer comment forms’ negative comments went from 9% to 3% (note: the industry standard is a maximum of 5% for 4- and 5-star hotels).
- Numerous ergonomics and safety improvements were identified by employees and implemented in the various hotels.
32. 10. Most effective ergonomics programs are an integral part of the design process -- not an Ility. Study by Ed Jones and myself of DoD Major System Development Programs over 10 year period.
Results:
- Effective programs: Ergonomics was an integral part of the
engineering design team.
- Ineffective programs: Ergonomics was treated as an “ility”, like
reliability, maintainability, etc.; only could make input after
subsystem or item was already designed (i.e., band-aid
changes only).
33. 11. participatory ergonomics is essential to successful interventions! Participatory ergonomics: Involve employees at all levels to insure success.
They know problems with their jobs best.
They know what ergonomic alternatives will be most satisfying and acceptable to them.
Get employee “buy-in” to changes.
Establishes a true ergonomic safety culture – the proven way to sustain improvement gains!
34. 11. Participatory ergonomics is essential to successful interventions! Example: Food Service Stands Redesign: Dodger Stadium
35. 11. Participatory ergonomics is essential to successful interventions! Example: Food Service Stands Redesign: Dodger Stadium
Results

51. 16. User centered design, rather than technology centered design, is the sure way to success.
First determine what tasks operator can do best and assign them to the operator.
Then design and/or select equipment, machines, etc. to assist operator and do what is “left over”.
Result will be better job design, improved productivity, and fewer design induced human errors.
52. 16. User centered design, rather than technology centered design, is the sure way to success.
Example: Replacement of Forklift Truck Lines.*
Forklift manufacturer, Raymond Corporation, had gone from 60% to 30% market share.
Alan Hedge’s HF lab at Cornell and Pelican Design in NYC participated with Raymond in designing two new forklift trucks using HFE principles and a user centered design approach.
*Alan Hedge, Personal Communication and supporting materials, 1996.
53. 16. User centered design, rather than technology centered design, is the sure way to success. Example: Fork Lift Truck Redesign
Results: Raymond regained its market share; stock value rose from $6 per share to $21 per share in three years.
54. 17. Employee ergonomics training is important for safety, health, and productivity. Example: Ergonomics team training.
Ergonomist Bill Brough of Washington Ergonomics conducted a one-day seminar for cross-disciplinary teams of engineers, human resource management personnel, and safety/ergonomics committee members from seven companies insured by Tokyo Marine and Fire Insurance Company.
Six of the companies used the seminar materials and data to implement a participatory ergonomics program; one did not.
55. 17. Employee ergonomics training is important for safety, health, and productivity. Example: Ergonomics team training.
Results*
For the six companies that did implement their training, reported strain-type injuries dropped from 131 in the six months prior to the training to 42 in the six-month period ending 18 months later for a net savings of $1,348,748.
For the company that did not implement, the injury rate actually increased during the same 18-month period.
*Bill Brough, personal communication and supporting documentation, 1995.
56. 17. Employee ergonomics training is important for safety, health, and productivity. Personal Example: Small Rattan Furniture Factory.
Manager and workers in a small factory I built in the Philippines were from a rural background. Consequently, they had little conception of basic safety and ergonomics.
Minor injury rate for 8 workers for first six months was one per week, and one significant lost time injury every two months.
I conducted a two-day basic ergonomics and safety training program for the manager and the senior worker. As part of the training, we did a hazard analysis of the factory.
The manager and senior worker then taught the other workers (who spoke poor English) in their primary language.
57. 17. Employee ergonomics training is important for safety, health, and productivity. Personal Example: Small Rattan Furniture Factory.
Results
Minor injuries dropped from 1 per week to 1 per month.
Major (lost time) injuries dropped from a rate of 6 per year to zero
(for the two years that I continued to observe).
The ergonomics knowledge gained was effectively used by the
manager and workers to both improve the workplace and refine
some of the furniture designs.
58. 18. Collaboration invariably works better than confrontation.
Well documented in the social psychology literature.
It has been my observation and personal experience (e.g. design of the Air Force C-141, mentioned earlier) that when the ergonomist respects the ownership and design expertise of the design engineer for his/her part of the project, and is collaboratively supportive of that engineer, that engineer is likely to be far more open to, and accepting of, the ergronomist’s input.
Further, once the ergonomist makes a recognized improvement to an engineer’s design (i.e., establishes credibility) the ergonomist will have more work requests from the design engineers than s/he can handle.
59. 19. Ergonomists can be effective system integrators on system development projects.
Our involvement across subsystems and components enable us to see possibilities and problems that others do not.
Examples
Possibilities: C-141 Medical Evacuation Configuration
Problems: B-70 Incompatible Hydraulic Systems
60. 20. Macroergonomics: The key to dramatic work system improvements. Macroergonomic interventions can dramatically improve health, safety, and productivity by 50% - 90% or more.
