Values are important to any work environment. I give A4 page with each value listed down the left hand side, a column saying how my direct report should be showing those values, a column with any development and then a column to show progress.
At each fortnightly meeting we have a quick review and they discuss how they have illustrated those values.
It shows my commitment and it also keeps the values at the forefront of the teams minds.
At the team meeting we then celebrate any great ideas or accomplishments.
