A Network Integration Evaluation (NIE) is an assessment of newly developed systems held twice a year by the U.S. Army. The NIEs have several functions. They provide critical operational test information for systems developed by the government, as well as evaluations of commercially developed systems to fill network capability gaps identified by the Army. During the NIEs, the Army integrates new systems before fielding to lessen the associated burden on operational forces. NIEs also help the Army perform a comprehensive evaluation of new systems in an environment that models actual battle, resulting in recommendations by soldier and system evaluators on whether to field, continue to develop, or discontinue evaluation of these systems.
