In addition, customers can count on Airborne Systems knowledge of recovery system controller design to support their own designs. Our full knowledge of BIT integration and pyrotechnic device safety and testing are available to support our customers’ controller design and development requirements.

Program Management

Airborne Systems experienced managers provide customers extensive and thorough program management ensuring each program meets identified objectives.

Airborne Systems recognizes that effective project management is one of the key elements required to ensure successful execution of any project. Our Space and Recovery Systems team are experienced project managers who prepare a detailed report of cost, schedule, and technical performance on a regular monthly basis. This cost, schedule and technical performance reporting can be a method to achieve significant cost improvement.

Airborne Systems routinely utilizes schedule management tools such as MS Project to develop an integrated master schedule and then monitor and track progress. As required, Airborne Systems can provide program control and reporting using an earned value management system.

Airborne Systems uses the Syspro management information system which provides timely and accurate cost tracking and reporting, as well as parts / inventory status and purchasing functions.

In addition to tracking against the agreed contract cost, the Airborne Systems program manager regularly reassesses progress against each work breakdown schedule (WBS) item and compares the expenditures against the work completed. This data is presented via estimate to complete / estimate at complete reports. These data, when combined with the progress tracking and the integrated master schedule allows earned value to be assessed and reported.

Airborne Systems has an established supplier base to support its engineering and large-scale manufacturing operations. All suppliers of parts and materials are assessed against Airborne Systems requirements before being entered onto an approved vendors list.

Configuration Management
