Presidential AddressHuman Factors and Ergonomics Society

53rd Annual MeetingSan Antonio, TexasOctober 20, 2009

(not to be confused with the Humor Factors & Economics Society)

Page 2: Assessing Human Factors/Ergonomics: How Well Are We Doing ...driving/publications/HFESPresidentAddress2009.pdf · 1. “Human factors” and “ergonomics” as broadly defined HFES

This talk was stimulated by Jeff Kelly and ideas he advocated concerning “Knowledge-Based Governance.”

Page 3: Assessing Human Factors/Ergonomics: How Well Are We Doing ...driving/publications/HFESPresidentAddress2009.pdf · 1. “Human factors” and “ergonomics” as broadly defined HFES

This talk is about…

1. “Human factors” and “ergonomics” as broadly defined HFES members, people with that job title, & kindred folk

2. the society (HFES) and other societies 3. quantification measurements, measures, & statistics, but not metrics

There are at least 4 types of statistics of interest: outcome, output, process, activity.

4. the big picture, but also to provide ideas that individual members can use at a personal level

For the latest info on quantification, see the health care literature.

The US population has grown 0.949% / year, so there are relatively fewer of us (HF/E). Fortunately, that is not the full story.

Reportedly, for all professional societies 1.  Membership is down overall. 2.  The membership is graying. 3.  Relatively fewer young members are joining. 4.  Specialization is increasing.

Are these statements true? If they are true, by how much and why? What should we do about it?

We need the appropriate statistics.

We are doing better than all publications and “human factors” is doing as well as engineering.

Ask

Without using your iPhone to go on line and search, does anyone know what the most “relevant” ergonomics title is for 2009?

What would you guess?

Ergonomics is the most common term in “average worldwide traffic” over time.

Go to trends.google.com, type in search terms

But, the most news is about usability.

“Horseshoe” has greater average worldwide traffic over time than human factors, ergonomics, or usability.

But, recently, there is more news about usability than horseshoes.

My main points 1.  Our profession seems to be doing ok. * membership & attendance, publication counts, web citations, standards, forensics * There is much more to the story than time permits.

2. Frequency counts of key words in data bases and other statistics are useful in assessing the human factors and ergonomics profession, and hopefully, your organization and yourself.

3. Quantifying how we are doing in terms of outcomes, output, process, and activity statistics is essential to wisely allocating our limited resources.

But...

Page 29: Assessing Human Factors/Ergonomics: How Well Are We Doing ...driving/publications/HFESPresidentAddress2009.pdf · 1. “Human factors” and “ergonomics” as broadly defined HFES

What we do and how we do it is not always a calculated decision based on statistics.

Ask:

How many of you have seen the TV program “Dirty Jobs?”
