“…Official federal Next Generation Enterprise Network (NGEN), Warfighter Tactical Information Tactical (WIN‐T), Global Information Grid (GIG) ,, and Geostationary Environmental Satellites (GOES) program requirement documents served as the data sources for textual analysis of stakeholder requirements statements and GAO reports served as the data source for system performance. These government system programs are developed through the DoD Acquisition System (DAS) framework by which the DoD provides effective, affordable, and timely correct systems to the warfighter . All the case studies are government system concerned with Information Processing Systems (IPS) which are built to aid the management and operation of federal organizations.…”

This paper focuses on the Requirements Engineering process's vital role during systems development as the preparatory point and critical foundation of Systems Engineering. This paper proposes a framework for structuring decisions, based upon the INCOSE Decision Management Process that improves decisions early in the System Life Cycle. This paper introduces and applies the Nexus Engineering Execution Generation (NEX GEN) framework, a novel and unique capability to improve requirements by enabling a prediction of their impact on expected systems' performance to gain efficiencies in budget and acquisition. Using this framework defines requirements in a quantitative manner to determine documented requirement issues. Regression analysis indicated a statistically significant relationship between the predictor variable of ambiguity (linguistic quality attribute) and the response variable of system performance (usability metric). This study provides a framework and metrics as a complementary method for the development of requirements in a theoretical manner for the reflective practitioner. This framework is demonstrated through multiple federal system program case studies.

“…Most of the views of SE presented by current standards and handbooks are primarily process-centric. Nevertheless, SE processes are not sequential, and the tasks are performed in a parallel and iterative manner (Chourabi et al, 2010). Each step may produce engineering artifacts, such as technical documents.…”

“…Data shared between engineering domains can be analyzed in an overall context to detect inconsistencies and provide means to generate overall project metrics. Chourabi et al (2010) propose a flexible ontology-based schema with formally defined semantics to enable the capture and reuse of SE experience. It contains the fundamental concept for a holistic SE knowledge model.…”

“…SE is very creative in nature and evolves in an unpredictable manner. However, this makes generating a shared conceptualization of the SE body of knowledge very challenging (Chourabi et al, 2010;Honour and Valerdi, 2014). Although SE is proven to be the answer to many complex questions associated with cross-organizational integration, there is no universally accepted theory within the SE discipline.…”

“…However, there are also some limitations that restrict the application of SE best practices. It contains sufficient terminologies that describe the SE domain but are often intertwined and ambiguous (Chourabi et al, 2010). With continuous revisions, the same concepts are referred to by different terms, and the linkages between the two editions are complicated to identify (Di Maio, 2011).…”
