Welcome to SITIS - Instructions

What is SITIS?

To facilitate greater understanding of the proposals, DoD SBIR/STTR has created the SBIR Interactive Topic Information System (SITIS), an online application that provides technical clarification on each solicitation topic. In SITIS, a questioner and respondent remain anonymous and all technical questions and answers are posted electronically for general viewing.

The SITIS Workflow

Questions posed through SITIS are directed to the appropriate Technical Point of Contact (TPOC). Questions must deal with the technical aspects of topics; any other types of questions will not be accepted. Questioner and respondent remain anonymous and all questions and answers are posted for general viewing throughout the solicitation period. Do not use this system to ask general SBIR/STTR program questions. Call the Help Desk M-F between 9:00 am - 6:00 pm ET at or email anytime if you have questions regarding proposal preparation, format, and submission. If you do not have the most recent DoD Program Solicitation, it is available online here.

During the DoD SBIR/STTR solicitations pre-release period, proposers may ask technical questions about a topic by contacting the topic manager listed in the solicitation directly or by submitting questions through SITIS. Once the solicitations open to proposals, only written questions submitted through SITIS are allowed.

Key Dates

Our goal is to have answers available within seven working days of submissions. SITIS will post questions that are pending replies and will follow-up with TPOCs, if necessary. Questions posted may or may not receive individual responses, at the discretion of the responsible DoD TPOC. The success of the system is contingent on the willing participation of the TPOC. SITIS cannot guarantee that all questions will receive a reply.

SITIS will cease accepting questions two weeks prior to the solicitation close date in an effort to obtain all answers prior to solicitation closing. It is highly recommended that proposers send in queries no later than three weeks prior to solicitation closing date, and that proposers monitor the information in SITIS relative to the topic(s) to which they are submitting proposals. SITIS will maintain all topic data, including previously answered questions, throughout the solicitation period.
