Wall Street Journal Special Section on Product Design

I'm a few weeks late in reporting on this, but the WSJ had a very relevant section in the Monday, June 23rd edition, that you can access online.   Form and Function contains a series of case studies on recent product designs, ranging from golf clubs, to blue jeans, to power tools and even a Buick.

What each of these min-articles has in common is a focus on the role of user research, human factors and usability in the success (and sometime failures) of products. 

One of the more interesting examples discusses the MK Diamond portable masonry saw (pictured here).  It's a clear demonstration of what happens when you don't design for your users appropriately, and then learn from your mistakes.  And while I could argue the finer points of the described design research (e.g. risks of relying on focus groups for identifying requirements, using product designers as representative users, etc.), let's be happy with this sort of message getting across to a mainstream audience:

"The completed product, released in 2003, was an immediate hit, selling 3,120 units in its first year. But through customer feedback, the company began learning about design flaws in the BX3.

For example, the design assumed that most masons would operate the pull-down handle that brings the saw into cutting position with their right hand. It turns out, though, that masons typically grip the material they're cutting with their right hand and pull the handle with their left. That made the handle somewhat awkward for many users.

The company also realized there had been a critical flaw in its design process: It had conducted focus groups with contractors and suppliers who would buy the saw, but not the masons who would actually use it."

"After four years, MK Diamond decided to redesign the saw, and invited masons to its focus groups...designers became familiar with the BX3 by mimicking its everyday use -- carrying it around, transporting it in a pickup truck and cutting cement blocks. All that was videotaped and photographed, and the designers examined the images to help them find ways to make the saw easier to use.

One conclusion was that the saw folded in a way that required a mason to extend his arm outward while carrying it, causing shoulder strain. Tweaking the design, so the user could hold the folded saw closer to his leg, would make it seem lighter and reduce the strain"
