Facilities are the entire physical infrastructure necessary to integrate, operate and maintain the equipment. The facilities assessment includes conducting studies to define necessary facilities or facility improvements and determining locations, space, utilities, environmental, real estate, and equipment needs.

Aspect consider the need for facilities as part of the Supportability Analysis process, which aims to influence design hence minimise the need for new or modified facilities.  By assessing facilities requirements at this early stage of the product lifecycle, Aspect can provide a substantial life cycle cost reduction.
