Master the Box

Master the box 1

“Constraints inspire creativity.”  Christopher Isaac “Biz” Stone, co-founder of Twitter. I recently asked a young engineer if he knew from where the phrase, “Think Outside the Box,” came. “Taco Bell?” he replied tentatively.

I asked a few of my other younger colleagues, and to a person, they had no idea where the phrase came from.  As far as they were concerned, it could have come from the boxing ring, the packaging for Fruit Loops, or televisions before flat screens.  They knew what it meant, though, and were fervent in their support of the idea for which it was a metaphor:  that innovation was paramount and that we should all be seeking disruptive technologies.

The Nine Dot Puzzle

I first encountered the phrase at a management seminar for technical types that I attended in the early 1980’s. At one point in the seminar, we were divided into groups of three (why groups of three, I don’t know) and told to draw nine dots in a three-by-three matrix.  Then we were instructed to figure out a way to connect all of the dots with as few lines as possible, drawing the lines without lifting our pencil.  We ended up with several versions, each drawn with five lines, and settled on the one shown above.

When the facilitator polled the groups, each one reported that they were able to connect the dots with five lines.

The facilitator laughed.  “You are all such engineers, trapped by your perceived constraints.”  He announced that it was possible to connect the dots with just four lines, and then went to his flip chart and proceeded to draw this figure:

Over the objections of some and the murmurs of assent from others, he pronounced that we all had to learn to “think outside the box.”  With that, he dismissed us to a lovely buffet lunch and told us that we would start again in 30 minutes.

Thinking Outside the Box

At lunch, some were annoyed, some felt duped, but many were intrigued.  At my table, someone asked, “So, are we constrained to use Euclidean geometry?  Because in projection geometry, parallel lines intersect at infinity.”

“Yes,” someone else responded gleefully.  “Three lines are enough”.

Another person at the table, dabbing at the salad dressing that he had dripped on his too-wide tie, offered, “Are we constrained to treat our dots as infinitely small mathematical points, or are they dots with scale and dimension.  If that’s the case, we don’t need Euclidean geometry.  We just need a bigger sheet of paper.”  Then, on the back of an envelope, he drew this:

The one woman at our table, June from process development, asked, “Are we constrained to draw straight lines?  Because if the line can curve, we can connect all the dots with just one line in the shape of a big figure S.”

Well, my lunch companions were having none of that.  The men at the table explained to her in no uncertain terms that curves were not lines at all, that using a curve completely violated the premise of the puzzle, and they wondered aloud “just exactly what was she thinking.”  (I’m sure I wasn’t involved in this patronizing display of nerd machismo.  At least that’s how I prefer to remember it now.)

Testing Assumptions

The thing I remember most vividly from that lunch (besides the shame I later felt because I realized that June was on to something but I was unwilling to take her side) is that all of the alternate solutions to the nine dot puzzle required that we go outside the box.  However, while our solutions went outside the box, that wasn’t where our thinking went.  Our thinking went to the assumptions we had made about the constraints, about what we had assumed was true.

First, we had assumed that we needed to stay inside the box, a constraint from which the facilitator freed us.

Second, we had assumed that we needed to construct a solution based on Euclidean geometry.

Third, we had assumed that the dots and lines we were drawing were pictorial representations of mathematical abstractions.

When those assumptions were tested, better solutions resulted.

The only assumption that we failed to challenge (and it was a miserable failure) was the assumption that a woman could not contribute in any meaningful way to a technical discussion.

Master the Box

In order to consider the constraints of a problem, one must understand the constraints of the problem.  For many, the fetish of “thinking outside the box” has become a metaphor that has lost its meaning, just another business cliché.  Increasingly, I find that when I hear people enjoining others to “think outside the box,” I want to encourage them to take a deep breath. Have they already made the implicit assumptions explicit?  Do they know what the accepted constraints are and why those constraints are there?  Do they understand the box?

It seems to me that before we worry about thinking outside the box, it is important that we first master the box.
