- Start now. Why hold back your thoughts for improvement until the weekly, monthly, or quarterly meeting?
Every day something isn't shared is a day lost without that knowledge (and you're trying to create a great team, not a mediocre team, yes?). Leadership is about solid and ongoing reinforcement... daily (not monthly or quarterly). Small, frequent, and consistent communication on the fundamentals makes it more likely the fundamentals won't fall through the cracks (which seems to have happened in too many places, hasn't it... think about when you're the customer, patient, patron, etc.). Use a card to start a conversation that helps keep things top-of-mind. Have it waiting for someone standing in their keyboard, placed on their desk, or inserted into a book.
- Follow up. Talk with your team about the fundamental you're using.
For a more personal touch, do it individually - maybe a 5-minute talk. "So, what do you think about that Ego idea?" Then listen (completely) and if appropriate, share what you like or don't like about it. Ask in what areas they feel they need to improve. To encourage truth, first share where you need to improve. This'll increase the chance of you being seen as human and clear the air for a more valuable conversation. "I have a hard time not complaining about things that are out of my control. Such a waste of time. How about you?"
- Reinforce. Come back to each issue frequently - especially when someone models a point particularly well... "Congratulations to Bob for being awake and seeing that opportunity last week. That's what we're talking about when we're creating our own luck."
Privately, or in a group setting (if you've got a particularly killer-high-trust-I've-got-your-back-you've-got-mine team) address any mistakes quickly so they don't continue. If you made the mistake, even better to share in a group setting... "I missed that opportunity to Smove yesterday with the Hendricks account. I should have had more of a sense of urgency in handling the proposal they requested." It gives all of us hope when those we respect share our challenge to get everything right.
