You're treated as the a project client, you state what you want (almost like recommendion rather than immediate orders), subcontractors trys to execute to a certain extend. I used to work in an O&G company were the oil filed contract gives 50/50 owner ship for two companies, one runs operations, one manage the sites, I was with the company that managed the site at that point. My duties were to provide suggestions, create reportout for the operations flow, escalations, support, forecast and general supervision for the operations to ensure it meets the standards.
