Product managers don’t build products; they make decisions. Good decisions save time, money, and stress. Here, we break down what makes a good decision and the principles of the decision-making process.

Product managers (PMs) don’t build products. However, what we do contribute is something equally tangible: decisions. For any given day we can make hundreds of choices.
