iterative trial and error

While the process was difficult and time consuming, Pete and his crew never believed that a failed approach meant that they had failed. Instead, they saw that each idea led them a bit closer to finding the better option. And that allowed them to come to work each day engaged and excited, even while in the midst of confusion. This is key: When experimentation is seen as necessary and productive, not as a frustrating waste of time, people will enjoy their work – even when it is confounding them. 

The principle I’m describing here – iterative trial and error – has long-recognized value in science. When scientists have a question, they construct hypotheses, test them, analyze them, and draw conclusions – and then they do it all over again. The reasoning behind this is simple: Experiments are fact-finding missions that, over time, inch scientists toward greater understanding. That means any outcome is a good outcome, because it yields new information. If your experiment proved your initial theory wrong, better to know it sooner rather than later. Armed with new facts, you can then reframe whatever question you’re asking....

There is an alternative approach to being wrong as fast as you can. It is the notion that if you carefully think everything through, if you are meticulous and plan well and consider all possible outcomes, you are more likely to create a lasting product. But I should caution that if you seek to plot out all your moves before you make them – if you put your faith in slow, deliberative planning in the hopes it will spare you failure down the line – well, you’re deluding yourself. For one thing, it’s easier to plan derivative work – things that copy or repeat something already out there. So if your primary goal is to have a fully worked out, set-in-stone plan, you are only upping your chances of being unoriginal. Moreover, you cannot plan your way out of problems. While planning is very important, and we do a lot of it, there is only so much you can control in a creative environment. In general, I have found that people who pour their energy into thinking about an approach and insisting that it is too early to act are wrong just as often as people who dive in and work quickly. The overplanners just take longer to be wrong (and, when things inevitably go awry, are more crushed by the feeling that they have failed).  There’s a corollary to this, as well: The more time you spend mapping out an approach, the more likely you are to get attached to it. The nonworking idea gets worn into your brain, like a rut in the mud, It can be difficult to get free of it and head in a different direction. Which, more often than not, is exactly what you must do.
