Requirements Engineering
RGI performs requirements engineering activities consistent with CMMI and DoD5000 practice. Expertise includes requirements decomposition from Customer Requirements / Operational Requirements Documentation to Sub-system and Component level Critical Item Development Specifications, using tools such as Doors and RequisitePro.

Analysis Of Alternatives (AoA) / Trade Study
RGI performs high quality, objective concept, component and technology selection by applying industry standard methodologies such as Analytic Hierarchical Process (AHP). RGI provides a fully facilitated approach that enables high utility outcomes aligned with customer needs.

Architecture
RGI is able to support DoD and industry standard Enterprise Architecture, supporting frameworks such as DoD Architecture Framework (DoDAF), C4ISR, Federal Enterprise Architecture Framework (FEAF) /Zachman. Toolsets include Popkin System Architect and Rhapsody..

Functional Design
RGI applies Object Oriented Analysis (OOA)/Object Oriented Design (OOD) methodologies, in the form of Unified Modeling Language (UML) and Use Cases to capture and derive functional requirements and design.

Technical Performance Metrics
RGI is able to support reporting and management of technical performance measures, such as Weight/Center of Gravity/Interia, Cost (Unit Cost and Lifecycle Cost), Reliability (Mean Time To Repair (MTTR), Mean Time Between Failure (MTBF)) and Component level requirements.

Modeling & Simulation / Verification
RGI performs a wide variety of system, sub-system and component level design verification, including Finite Element Analysis (FEA) (Linear/Non-Linear Stress/Strain), Computational Fluid Dynamics (CFD), Thermal Analysis, Rigid Body Dynamics and Kinematics, Discrete Event Simulation, using tools such as Pro/Engineer, Ansys, Dads, Adams and DELMIA.
