If you don’t have enough data to make a decision, you’ll need insights to inform your opinion. Insights can be key learnings about your customers or your market or your product space—something substantial that gives you an intuitive feeling for what you should do. You can also get outside input: talk to the experts and confer with your team. You won’t reach consensus, but hopefully you’ll be able to form a gut instinct. Listen to it and take responsibility for what comes next.
