Systems Engineering Glossary
The association of effort (cost) to the accomplishment of technical objectives.
|Earned Value Management (EVM)|
Macro-level behaviors that cannot be predicted from studying the micro-level behaviors in isolation.
The final production product that when assembled or completed is ready for deployment
|Engineering Change Proposal (ECP)|
|Engineering Change Request (ECR)||
A technical change request to the technical baseline submitted to the Configuration Control Board (CCB).
|Engineering Design Heuristics||
Statements, often derived from experience, about what makes a design better.
|Engineering Gate Review|
|Engineering Review Board (ERB)||
The highest-level engineering forum convened to provide technical oversight to assist the Project Manager. Engineering Change Requests (ECR) are reviewed to determine their impact and necessity to prior consideration for incorporation into a system baseline.
|Enhanced Functional Flow Block Diagram||
A block diagram that represents control flows and data flows as well as system functions and flow.
A holistic view and a way for enabling design, development, and communication and understanding of the enterprise. It helps manage the complexity of the enterprise by aligning business strategies and implementations, and facilitating rapid change.
|Enterprise Decision Model (EDM)|
|Enterprise Service Bus (ESB)|
The minimum accomplishments necessary to enter into the next life cycle phase or level of technical maturity.
The standards by which accomplishments of required technical performance may be assessed.
|Event Stream Processing (ESP)||
The event detection triggers that activate Service-Based Architecture (SBA) services. This is helpful when an anomaly or an opportunity occurs.
A product life cycle that relies on existing technology and enhances system capabilities as new technologies become available.
The accomplishments that must be demonstrated before an effort can progress further. The criteria usually are selected to monitor progress on technical, schedule, or risk areas.
