The SBIR program is structured in three phases: 1. Phase I: Feasibility Study - This phase establishes the technical merit, feasibility, and commercial potential of the proposed R/R&D efforts. 2. Phase II: Development - This phase continues the R&D efforts initiated in Phase I, with a focus on the development of a prototype or process. 3. Phase III: Commercialization - This phase is for the commercialization of the results from Phases I and II. However, SBIR does not fund Phase III.
