Principles and Techniques

INL Systems Engineering has supported numerous projects at both the INL and other Department of Energy sites, and for many Department of Defense customers, in providing the following core Systems Engineering functions and capabilities:

Mission Definition / Function Analysis
INL systems engineers lead many projects in analyzing mission needs and aligning the current state of the project or system with those needs.  This effort also examines the current functions of both the project and the potential solution in light of the mission needs to see if they are aligned for optimal solutions.

Requirements Identification, Analysis, and Management
Requirements range from the highest level (usually mission need or functional requirements) down to specifications for individual parts or system components. INL systems engineers identify requirements through discussion with customer technical leads and solution providers, as well as through examination of governing laws, codes, standards, and contracts.

Trade Studies / Alternatives Analysis
Trade studies and alternative analyses are performed any time a project needs to select from two or more options.  INL systems engineers use a broad base of experience and expertise to affect these efforts and guide informed, defensible decisions through the assimilation, correlation, and/or distillation of available information.

System Synthesis, Integration, and Control
INL systems engineers provide support to project managers and project engineers by integrating the many project and system functions and components.  This includes ensuring consistent communication and collaboration between project elements, as well as documenting and disseminating key decisions and technical baseline changes.

Readiness / Startup Support (Verification and Validation)
System startup usually requires a readiness review where all requirements are validated in the system design and operating procedures. Since requirements for test and evaluation come directly from the technical and functional requirements, INL systems engineers are often in the best position to identify these connections and oversee verification and validation activities.
