quality and efficiency

today go to university, just because of the meeting.
today meeting is mention about the efficiency of the member in the team.
i can observe that our team quality is not good as previous, example is me, i do not know anything, even i am  a department assistant, but i know where is my standard in the team and what is my knowledge standard in the team. my head is more efficiency and more knowledge than me, i cannot replace his position in current and cannot imaging what will happened when he leave the team.

in my mind i have imaging if i apply classes for the team and i know is not efficiency and useless
