Competition is useful. Usually, cooperation is better. Incentives have their value, internal motivation is massively more powerful. While high performance leaders DO focus on achieving their goals and delivering positive results, part of that is built around healthy relationships.
Take the time to get to know your team members. Listen to their stories, their heart songs, their hardships, their views. When they achieve their goals, reward them with signs of your appreciation. And, when they consistently act as responsible adults within your relationships to achieve those results, show your appreciation. It doesn't need to cost any money. Sometimes a "thank you" is enough.
We need healthy relationships to sustain trust. Without trust, a team member could be tempted to game the system in order to hit the numbers. That's not what you want. Sustain the relationships to keep the results both strong and ethical.
Be careful about rewards that only recognize results. Reward both healthy results AND healthy relationships.
