Technical Inquiries (TIs)

The core function of DSIAC is to answer technical questions using our in-house technical personnel, vast DoD information resources, and our extensive network of subject matter experts (SMEs). DSIAC has technical staff available to conduct technical research in order to give you a head start on your analysis or study in any of our technical focus areas. We offer a free 4-hour TI research service or, for slightly larger research efforts, we offer an extended technical inquiry (ETI) service.

Technical Inquiry Features

Our TIs include the following to help you with your research:

magnifying glass
Literature Searches

A curated bibliography given a technical topic

Document Requests

Dissemination of technical reports to authorized users

User Icon
SME Referrals

Contacts and connections with relevant, technical SMEs

Accounting business meeting concept. Photo young businessman crew working with new startup project in modern loft. Generic design notebook on wood table, talking smartphone. Horizontal, film effect

Free Technical Inquiry Services

DSIAC's free TI service offers 4 hours of free research per inquiry on any topic within our technical focus areas. Typical TI efforts may include answering technical questions, literature searches, document requests, or referrals to SMEs. Completed responses are compiled and delivered to the inquirer in less than 10 business days. Registered users can submit TIs online through the provided form or by phone.

Extended Technical Inquiry (ETI) Services

ETIs are externally funded research efforts that go slightly beyond 4 research hours. ETIs require between 5 and 160 technical hours of research, with a $50K maximum ceiling and period of performance up to 2 months.

Notable Technical Inquiries

Notable TIs are summaries of the most recent and impactful works done by DSIAC in response to technical inquiries that were submitted by defense systems members. These summaries are intended to give our community a sampling of the wide range of questions presented and responses produced by DSIAC under the free 4 hours of information research support.
