Interesting list that you plan and very true, I focus a lot on coherence and transparency, it is true that it is not always possible to say everything to the team, it has happened to me and it happens to me. But the issue of giving credit to them I always do.
This list is not only useful to apply when you have a team but also to lead ourselves. I liked it a lot.
Credit should only be given when deserved, I never reward teams or individuals for no reason; but encouragement should always be given because that helps promote the right attitudes, actions and better results.
Giving encouragement is necessary and essential to be a good leader, I have had people in charge who thought they couldn't do this or that and they have succeeded. That is how it is.
