Software Engineering

Leading Modernization of Legacy DoD systems implementing DevSecOps Processes with Agile Methodology for Software Development Life Cycle (SDLC).   We have demonstrated our proficiency in applying our SDLC approach successfully for DoD Software Engineering customers on key programs. Our standard SDLC process employs a structured engineering approach that is based upon industry systems engineering standard, compliant with SEI CMMI guidelines, and DevSecOps-Agile developmental practices.

We utilize the governments Software Engineering Environment (SE2) for software development and testing.  Nexagen employs and adheres to the DevSecOps Agile SCRUM framework and incorporated testing activities into the agile cycle.   Systems and Software tests include Unit Testing, Functional Testing, Cybersecurity (IAVAs, STIGs, Software Assurance), Regression Testing, Preliminary Qualification Tests, Formal Qualification Tests, 508 Compliance, Interoperability Testing, Performance testing, User Acceptance Testing, Fuzz Testing, and other integration and testing required to ensure the developed software is suitable for its intended purpose.
