The purpose of this thesis is to provide a Joint Deployable Intelligence Support System (JDISS) Communication and Imagery Application Guide for New Users. These two applications, together, are the core of the JDISS program. Both applications were examined to identify functions and processes that are difficult to understand as well as functions and processes that lack sufficient instructions for new users. The supporting JDISS Desktop and Utilities applications were added to provide the knowledge base required for the new user to use the Application Guide as a stand-alone document. Other JDISS applications, such as Office Tools, E-mail, Intelink, etc., are not included due, in part, to a common thread with other programs that the new user should already be familiar with, but mostly due to the adequate help instructions readily available within the JDISS main desktop help function. The JDISS program was developed to ensure that each of the U.S. Services and Agencies had an integrated intelligence system, and one that would provide a common data standard permitting interoperability both intra-service and inter- service. The Joint Staff, Director of Intelligence (J2), has highlighted JDISS in joint doctrine as the principal intelligence component for interoperability (JBOC, 1996). Therefore, this detailed, step-by-step JDISS Communication and Imagery Application Guide for New Users was developed and designed to help future JDISS users worldwide.
