Will your team get better just because they show up for work? Doubtful.
Coaching is the only, sustainable way to improve your team. Of course, your team needs training and communication, but coaching is the only way YOU, the coach/manager/leader, will be able to enable them to become better.
As a leader, you cannot rely on other leaders to improve their teams to compensate for weaknesses on your team. Each team leader must dedicate themselves to team improvement. Then, as a whole, your company becomes better.
Improve your coaching and you help your team members become better. Then your team becomes better. Your company (and your customers and communities) become better.
That’s a winning combination.
