If you’re a designer, you can become very stressed over a small product detail, something so small most customers may not notice. If you’re a product manager, you may attend to the product details without stressing over them because you see the bigger picture of how the product competes in the market and what the true competitive advantages are.
And this scenario scales. A business unit manager may fret over a $50 million decision. If you’re Jeffrey Immelt, CEO at GE, that’s not a stressful decision, the big decisions are about billions of dollars. So Immelt spends time coaching managers through the $50 million situations.
In short, I find the bigger the picture one considers, the less one sweats the small stuff.
