The Washington Headquarters Services (WHS) Acquisition Directorate is soliciting innovative commercial solutions through its Commercial Solutions Opening (CSO) under the Defense Department's authorities, specifically focusing on prototype projects authorized by various U.S. Code sections. The CSO aims to enhance defense capabilities by inviting participation from both traditional and nontraditional defense contractors, as well as non-profit research institutions, to foster collaboration on technology that can improve defense applications. The selection process consists of three phases: Solution Brief, Pitch, and Prototype Proposal. Submissions must reflect compliance with specified guidelines and be focused on practical solutions that meet defined Areas of Interest (AOI), with eligibility criteria including participation from nontraditional contractors or significant funding from private sources. The document underscores that proposals must be unclassified and restricts details of submissions that include proprietary information. Awards will be made based on agreed terms and conditions through other transaction agreements (OTAs), facilitating flexibility in project execution and allowing for iterative prototyping. The CSO also emphasizes confidentiality and compliance with legal requirements for disclosure and data usage throughout the selection process.
