My airman is incompetent

Hello to all. I need advice and guidance to deal with an airman that makes my life harder with his F$ck ups. Airman is constantly late, always shows up with bed head and out of reg hair. Does a horrible job at his job and is constantly making mistakes and it’s a constant pattern. I always clean up and do his work and repeatedly teach this 4 year Sra. This airman waits until last minute to inform of appointments and needs to switch days the day before. This airman is nice and respectful, outside of work he plays basketball and sometimes fishes with me at the base lake. How can I get this airman to get his shit together? I try talking to him about being late and his hair, I also remind him on the importance of communicating with myself and others, i inform him and teach him repeatedly how to do his job! I am tempted to write a Record of individual counseling (RIC)since I am not his rater. If more info is needed please ask. But I want to be Vague. If anyone knows how to commence a RIC or LOS please lmk. I’ve been a SSGt for 1Y3M and never issued paperwork but I feel I might have to.
