What are you doing for your team to develop it?
Our development and our team's development is never done. There's always something new to learn. There are always skills that are changing and need updating. The work is a work in progress.
Give your team the training they need. Help them to enhance their skills. Make resources available to them so that they can grow. It's better for your team members and it's better for you.
Enhancing your team's skills will improve your team's performance.
As a leader, that's your job!
