Her contracting patterns indicate a reliance on established small business partners capable of delivering mission-critical services under stringent security and operational standards, often requiring rapid mobilization and site-specific compliance. Stewart demonstrates a strong commitment to socioeconomic contracting, with 60% of her acquisitions structured as total small business set-asides under FAR 19.5.
