Consist of Assignment/Support Requests and drawings. For projects funded through the Smithsonian Astrophysical Observatory (SAO), the mechanism for formally requesting engineering support is to submit a form called an 'Assignment/Support Request' (ASR). An ASR functions both as an internal purchase order for engineering services, and as a planning document for engineering management. It serves the SAO Controller's Office as a funds obligation document, and the project Principal Investigator or Program Manager as a vehicle both for describing the engineering support required, and for negotiating specific staff assignments and project schedules with the Engineering Manager. Materials include correspondence, schematics, drawings, research notes, lists, and reports. Some materials are in electronic format.
