EMILY: I scaled back a lot. I cut two appetizers, I canceled the champagne fountain, and I reduced the catering staff to six servers, not counting the pointman.
Technically a pointman is the head of a military patrol, or in the US, the word is used to mean the person who is at the forefront of a particular endeavour. I think Emily just means the pointman is the person who is coordinating the party and giving the servers instructions, solving any little problem that might come up.
