Leadership
Delegate, delegate and delegate some more
Act the part
You are not a peer anymore
Treat people with respect
Communicate professionally (no gossip, no sarcasm)
Be approachable
Be a champion for the direction you're given. You can disagree in leads meeting but when the decision is made live with it and help your team make the best with it.
Establish a clear direction
Make sure you have a vision for how the team should work and communicate it clearly.
Communicate the expectations to the team so they can predict with some accuracy whether or not you will think things are going as anticipated.
Help the team improve
You need to find out the growth and career goals of each developer on the team.
Use that information to train them by letting them work on problems that they don't already have done or let them learn things that they wish to focus on.
Feedback
Feedback is when you tell someone how to improve the work that they do.
It can contain both negative or positive feelings for the person you give the feedback to.
Some people might have problems handling the negative feedback (things that was done wrong) and others the positive (things that was done right).
Do feedback in public to teach people how to give and take feedback.
Focus on what they should to make it better, not that something was done wrong.
Teach everyone that it's not a disaster to make mistakes.
Criticism / Praise
Do criticism in private and praise in public.
Address problems right away
Delegate
Don't over commit yourself with tasks
Let people grab tasks, assign the rest
Your team are or will soon be the domain experts if you let them.
Take interests and career goals into consideration
let people learn new skills and techniques
if possible avoid repetitive tasks
Provide challenges, not solutions
Create task that have the problem and the constraints.
You can provide suggestions for solutions but if you always do that they will not learn to act independently when needed.
