The Live Training Transformation (LT2) is a strategy that utilizes product line engineering development concepts and principles to guide the acquisition of the family of live training programs under the purview of U.S. Army Program Executive Office (PEO) Simulation Training and Instrumentation (STRI), Program Manager for Training Devices (PM TRADE). The LT2 strategy addresses a set of operational requirements defined by approved Operational Requirements Documents (ORDs), and is being transformed into an Army program as a Family of Training Systems (FTS) documented in the LT2-FTS Initial Capability Document (ICD). The LT2 product line management concept of operations focuses on the holistic requirements of all Live domain training systems, with the objective to maximize component reuse, reduce fielding time, minimize programmatic costs, and enhance training benefits afforded to the soldier. Through successful execution of the product line strategy, LT2 will deliver a set of common components that provide integrated and interoperable training solutions for live collective training across the home stations, Combat Training Centers (CTCs), deployed, and Joint training domains. This paper describes the innovative approach PEO STRI is using to manage the LT2 product line. In doing so it details the combination of organizations, processes, and technologies that encompass the LT2 concept to include the product line architecture known as the Common Training Instrumentation Architecture (CTIA). In addition, this paper describes how the LT2 product line is being used to support the Future Combat System (FCS) Training Common Component (TCC) program and how it will interoperate with other Army and Joint architectures in support of a Live-Virtual-Constructive (LVC) training and test solution.
