It's easy to get caught up doing work, and as a result neglect improving how effectively and efficiently we complete said work.
As leader, it's your responsibility to enable, support and develop your team members so as to make them continously better at practicing the responsibilities and skills expected of their roles.
Use the "People" tab in the Priorities-section of your Focus-dashboard or the separate My team-page to review the support-card of who report to you, and reflect on how you can best help them move forward.
For input into how to read and reflect the support card of each individual, please review the My team-documentation.
