A user analysis was performed to identify potential groups of users. The two primary user groups targeted for this effort were Emergency Responders and Casual Users. A Technical Feasibility Analysis assessed both user groups and identified threshold and objective performance requirements. The Feasibility analysis then identified currently available systems and modeled their predicted geolocation performance. The initial results indicate that the threshold requirements are achievable and that the objective requirements may be met under specific conditions. The confirmation that this capability is feasible with currently available smartphones was a key milestone in this effort. Based on those results, a Concept of Operations (CONOPS) then was developed to describe how the users will interact with MAGIC on their smartphones. The Technical Feasibility Analysis and CONOPS were used to guide the development of a complete system architecture and to capture high level system requirements. The System Description Document provides details of the MAGIC system's CORE model, which was used to define the system architecture and track requirements. A Business Case Analysis was also developed to identify trends in the current market, explore viable options for development and marketing to the targeted users, and make a recommendation for the development path IAI should pursue. The Business Case Analysis recommends developing MAGIC for the Casual User on Google Android supported smartphones first, with both a free "Lite" and for-purchase "Full" version of the application.
