“First, I like to determine the root cause of the problem,” Adrian said. “Then, I like to brainstorm alternatives, evaluate them and make a plan. During execution, I may adjust the plan.”
Stephanie said, “When a process erupts, I quickly put a patch on it. If my first impulse fails, I try something else. I just continue experimenting until a solution finds me.”
Adrian, by moving logically from one stage to the next, exercises linear thinking. Stephanie’s approach is less logical and more iterative. Which is better?
Tom Wujec gave many groups an assignment to build a tower out of spaghetti and tape to support a marshmallow.
Not surprisingly, the best performing teams in Wujec’s experiments were architects and engineers. However, kindergartners consistently outperformed business school students.
Business students, relying on linear thinking, spent a lot of time methodically planning and assigning team member responsibilities. When the plan failed during execution, they went back to the drawing board to regroup and revise.
Kindergartners simply began trying different actions without planning (an iterative approach). When an action failed, they quickly tried another. Their “try it and fix it” approach produced a better product in less time.
