Goldbelt C6 provides System Engineering Lifecycle (SELC) support. We focus on customers’ needs and user requirements, performing system requirement analysis and system maintenance development to support lower level system requirements derived from mission critical and business requirements. This includes validating existing business, mission, or user requirements for clarity, accuracy, and compliance with overarching customer requirements documentation; as well as providing lower-level requirements coordination that support the user. We assist with the development, accuracy verification, and management of System Engineering Life Cycle (SELC) documents in accordance with the System Development Lifecycle Methodology, including Software Requirements Document (SRD), Hardware Requirements Document (HRD), Design Specification (SDS), and Interface Design Specification (IDS). We perform system performance data analysis by collecting and analyzing data and providing recommendations and a course of action to improve efficiencies of system performance. These analyses and recommendations are used in the sizing and design of computer systems on which existing software operates.
