Topic Q&A  

Topic Q&A is now available on the Topics and Topic Q&A page in DSIP. Proposers may submit technical questions through Topic Q&A page at

Once DoD begins accepting proposals on May 18, 2022, no further direct contact between proposers and topic authors is allowed. All questions and answers are posted electronically for general viewing. Topic Q&A will close to new questions on July 25, 2022 at 12:00 p.m. ET, but will remain active to view questions and answers related to the topics until the CSOs close. 

Questions submitted through the Topic Q&A are limited to technical information related to improving the understanding of a topic’s requirements. Any other questions, such as those asking for advice or guidance on solution approach, or administrative questions, such as SBIR or STTR program eligibility, technical proposal/cost proposal structure and page count, budget and duration limitations, or proposal due date WILL NOT receive a response. Refer to the Component-specific instructions given at the beginning of that Component's topics for help with an administrative question.

Proposers are advised to monitor Topic Q&A during the pre-release and open periods for questions and answers, and frequently monitor DSIP for updates and amendments to the topics.
