Design is the articulation of intent to achieve a goal, including plans for executing that intention. We're engaged in design whenever we devise products, services, procedures, tests, policies, legislation, campaigns — just about anything in the modern knowledge-oriented workplace. And when we design, we risk error. Our design might not achieve all we hoped, or it might not achieve the goal at all. Or we might discover that the goal we were aiming for isn't what we actually wanted. So much can go wrong that attaining even a measured success sometimes feels thrilling.
Design errors are more common than we imagine. When a system produces disappointing results, we cannot always distinguish design errors from user errors or implementation errors. And we don't always know whether the system was being used in an environment for which it was designed. That's why we sometimes mistakenly attribute system failures to something other than design error, even when design errors played a role.
Because we usually use the term error for undesirable outcomes, the language we use to describe design errors carries connotations that limit our thinking. For this discussion, we use error to mean merely unintended as opposed to unintended and unfavorable. With this in mind, when a design "goes wrong" we mean that it didn't achieve the goal, or that we discovered an even more desirable goal. We must therefore classify as design errors those exciting surprises that bring welcome results. Typically, we take credit for these as if we intended them, but their sources are often simple design errors.
The Design errors are more
common than we imaginekind of design errors I find most fascinating are those that arise from the way humans think and interact. Let's begin with one of the most famous of group biases, groupthink.
Groupthink happens when groups fail to consider a broad enough range of alternatives, risks, interpretations, or possibilities. Groups are at elevated risk of groupthink if they aren't diverse enough, or lack sufficient breadth of experience, or feel infallible, or want to preserve their elite status, or have an excessive desire for order.
For example, if an elite review team is pressed for time and must review two designs — one by an elite development team, and one by a less accomplished team, it might decide to do a less-than-thorough job on the work of the elite development team so as to make time for careful review of the work of the less-accomplished development team. Because the review team values its reputation for getting work done on time, and because it feels an affinity for the elite developers, an error in the elite developers' work can squeeze through. That might not be a bad thing, of course. Some design errors produce favorable outcomes. Such beneficial errors are rare, but we ought not dismiss the possibility out of hand.

More articles on Problem Solving and Creativity:
- Poverty of Choice by Choice
- Sometimes our own desire not to have choices prevents us from finding creative solutions. Life
can be simpler (if less rich) when we have no choices to make. Why do we accept the same tired solutions,
and how can we tell when we're doing it?
- When We Need a Little Help
- Sometimes we get in over our heads — too much work, work we don't understand, or even complex
politics. We can ask for help, but we often forget that we can. Even when we remember, we sometimes
hold back. Why is asking for help, or remembering that we can ask, so difficult? How can we make it easier?
- New Ideas: Judging
- When groups work together to solve problems, they eventually evaluate the ideas they generate. They
sometimes reject perfectly good ideas, while accepting some really boneheaded ones. How can we judge
new ideas more effectively?
- How to Reject Expert Opinion: II
- When groups of decision-makers confront complex problems, and they receive opinions from recognized
experts, those opinions sometimes conflict with the group's own preferences. What tactics do groups
use to reject the opinions of people with relevant expertise?
- Problem Displacement and Technical Debt
- The term problem displacement describes situations in which solving one problem creates another.
It sometimes leads to incurring technical debt. How? What can we do about it?
Forthcoming issues of Point Lookout
- Coming May 29: Newtonian Blind Alleys: II
- Some of our decisions don't turn out well. The nature of our errors does vary, but a common class of errors is due to applying concepts from physics originated by Isaac Newton. One of these is the concept of spectrum. Available here and by RSS on May 29.
- And on June 5: I Could Be Wrong About That
- Before we make joint decisions at work, we usually debate the options. We come together to share views, and then a debate ensues. Some of these debates turn out well, but too many do not. Allowing for the fact that "I could be wrong" improves outcomes. Available here and by RSS on June 5.

- The Power Affect: How We Express Our Personal Power
- Many people who possess real organizational power have a characteristic demeanor. It's the way they project their presence. I call this the power affect. Some people — call them power pretenders — adopt the power affect well before they attain significant organizational power. Unfortunately for their colleagues, and for their organizations, power pretenders can attain organizational power out of proportion to their merit or abilities. Understanding the power affect is therefore important for anyone who aims to attain power, or anyone who works with power pretenders. Read more about this program.
