ICT Supply chain awareness, vendor illuminations and attestations (such as Bills of Materials/SBOMS) and explicit contractual disclosure obligations are changing the face of transactions for technology products and services. This session provides an overview of dramatic recent and emerging changes to business processes and transactions for the development, sale and acquisition of technology products and services. Governing rules (such as US Government FAR/DFAR contract regulations) and policies and best practices (such as Bill of Materials (SBOM) requirements are rapidly redefining mutual seller AND buyer transactional obligations, especially in Critical infrastructure markets, replacing the historic "buyer beware" caveat emptor model with a new Due Diligence encompassing mutually transparent information about product pedigree and provenance and buyer transparency about intended use and security environments. Prospects for further formalization in Uniform Commercial Code (UCC) and other contractual regimes and standards.
