Job Descriptions

On a recent viewing of our movie that Vickers says her job iot mkae others do their job. Janek says his job is fly the ship. Jackson tells Shaw his job to make ecerybosy safe and secure. But then Shaw corrects him to say this is a scientific expedition and no weopons are needed. In any kind of group effort there are4 certainly assigned jobs. THwere is also a person sort of looking over everything to keep the goal in mind as the tasks are being done. If, as Weyland says, Drs. Holloway and Shaw are in charge Shaw must not have been included in much of the key mission planning but were just pawns to be used by Weyland to achieve Immortality. In fact since David had to introduce himself to Shaw, Vickers had to introduce herself to members of the crew she didn't hire and Jackson had a job to do that Shaw did not approve od the 'true believers' were kept quite distant from the actual processes needed for a expedition of this size and magnatude. Speaking of David's Job Description who/what actually created his? Perhaps David's role was just to survive without losing his head. What's your Job?
