Communication skills to implement all other expected skills: Doesn’t much matter if one can set expectations or determine how to resolve conflicts if one cannot communicate them.
I include in communications skills the ability to understand the different filters that people put up that limit the communications. These filters can be based on many things including: different generations, personal experiences, personality, motivating issues amongst others.

Related to communication skills should be the ability to be an effective liaison between those below the supervisor and those above.
