Goldilocks and the Three Chairs or What Size Bear are You?

measuring-stick-3-bears-002If ergonomists were looking for a mascot, my vote would go to Goldilocks−yes, I mean the blonde chick with a poor sense of boundaries. I’ve been working in the field of ergonomics for more than 10 years, and lately, I’ve begun to feel a certain kinship with the story-book character from my childhood days.

Let me explain: a few months ago I was helping a colleague assess the ergonomics of her work station; she had recently moved to a new department, and was suffering from neck stiffness and pain. After a taking a few measurements, I was able to verify that her desk and chair were set too high for her stature. Once the work surface was lowered, I invited her to try out a variety of office chairs, and a few minutes later I heard her exclaim, “This one’s just right!” that’s when it hit me: Goldilocks is all about ergonomics.

You know how the story goes: our heroine wanders into the house of the three bears while they’re taking a walk in the forest and proceeds to break several rules of etiquette along with poor little baby bear’s favorite chair.

But note, in the midst of this mad behavior, there was also method: just like a professional ergonomist, Goldilocks worked with a set of Standards!

Using herself as a subject, Goldilocks determined the suitability of the objects she encountered in the three bears’ home in much the same way a human factors specialist (another term for ergonomist), tests products: that is, empirically, through observation, experience and experimentation.

Moving from room to room, she established the safe temperature for eating porridge, gauged her chair size as it corresponds to either small, medium or large ursus horribilis, and put her stamp of approval on what she judged to be the most comfortable mattress for a mid-morning snooze.

In the real world ergonomists and human factors professionals work with hundreds of different human measurements compiled into tables of Anthropometric data that help shape our understanding of human physical variation and ultimately form the basis for decisions that affect every area of human experience and endeavor.

manikin-scaleTake for example Ergotron. We manufacture mounting solutions for flat computer equipment, so we need to know how high a screen should be placed in relation to the keyboard, to ensure the safety, comfort and productivity of the computer user. A measurement which depends on the distance between the user’s eye and elbow.

But how does one define the term “user”?

By referring to an Anthropometric table, where data has been organized by gender, size and age, our designers know exactly what portion of the population to target. In some cases, a product will be designed to meet a range of sizes from the 5th percentile adult female to the 95th percentile adult male. If the product is meant to be used by school kids, the minimum and maximum heights are tailored accordingly.

Designing products that are universally acceptable is a daunting challenge for manufacturers, and ergonomists pay special attention to factors that might cause shifts in the Anthropometric data. The growing number of obese individuals in western society, has caused ergonomists to reassess the design of office chairs, and question the application of the Body Mass Index, a mathematical formula used by health professionals that takes into account both a person’s height and weight.

One of the earliest applications of anthropometry in Europe made it possible for law enforcement officers to identify criminals by body type or finger prints. NASA and the United States military in general, are major players in the field of ergonomics and human factors.

As for Goldilocks, I admire her relentless curiosity and the presence of mind she demonstrated in strange surroundings. If asked what she learned from the experience, I imagine she might say, “I’m a size Mama Bear−not too large and not too small. What size bear are you?”

That’s “THE END” of this story. More to come on what ergonomics means in the world of work.

How to Create Products that Delight Customers

Tuesday, November 4th, 2008

Pete Segar, SVP Product Innovation & Chief Technical Officer @ Ergotron

In planning future products, many companies put a lot of effort into standard techniques like Voice of the Customer.  These methods are good tools designed to prioritize customers wants and needs, and provide inputs on new products.

But I don’t think they are the best way to develop products that delight you, the customer.  Why?  Because the basic tenet of these tools is that they rely on a customers existing context, that is, your reply within the framework of what exists today.  You may respond saying faster, cheaper, different color, etc., which are all useful for creating a better version of a current product.  But it is rare that these methods lead to a disruptive new concept that will ultimately delight you.

My definition of a truly innovative product is one that gives you more than what you want in a way you could not have thought to ask for.

To develop a product like that, we have to focus on the workflow and “live” your experience.  This can be done through talking with you, understanding how you do work your daily process and what your fundamental challenges are.

To use our own products, install them in front of you and internalize what you like and dislike.  When we do these things over and over, and focus initially not on the product, but on what problems need to be solved, then true innovation can be created.

We make products that solve ergonomic and productivity issues for computer users.  Many of us at Ergotron are laptop users with port replicators, and a flat panel monitor at work.  We take our laptops home every night for work and teleconferences.  I call this the typical “road warrior.”  Three years ago, all these laptops sat closed on our desks in the port replicator, while we used single monitors.  The laptop screen wasted all day long.  We knew the productivity that can be gained by using dual monitors, yet we looked at these wasted screens and saw an opportunity.

We set out to solve the problem of allowing you to view your open, docked notebook and utilize it as a second screen.  And to do so in an ergonomic and convenient way.  As users, we knew the problem because we lived it every day.  Out of that problem came a unique product that nobody every asked for – the Neo-Flex™ Combo Lift Stand.

I have that product on my desk at home, providing the productivity of a dual monitor solution and the ergonomic advantages of a height-adjustable, swiveling stand in one compact unit.   This product is changing the way people work, and helps provide 10% or more productivity improvement for everyone using it.

The best way to be innovative is the “live the problem” that needs to be solved and to take a workflow view.  The best way to do this is to install and use your own products.
