Systems Engineering Glossary
Term | Main definition |
---|---|
Emergence | Macro-level behaviors that cannot be predicted from studying the micro-level behaviors in isolation. |
End Item | 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 | An engineering life cycle technical review that confirms that the developed engineering products are sufficiently correct and mature to continue the development to the next phase/ step. |
Engineering Review Board (ERB) | |
Enhanced Functional Flow Block Diagram | A block diagram that represents control flows and data flows as well as system functions and flow. |
Enterprise Architecture | 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) | A software architecture model used to design and implement communications between interacting software applications in a Service-Based Architecture (SBA). |
Entity | |
Entry Criteria | The minimum accomplishments necessary to enter into the next life cycle phase or level of technical maturity. |
Evaluation Criteria | 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. |
Evolutionary Development | A product life cycle that relies on existing technology and enhances system capabilities as new technologies become available. |
Exit Criteria | |
Failure | The inability of an entity to perform as intended. |
Family-of-Systems | A group of systems that provide similar capabilities that use different approaches to achieve the same goal. A family of systems does not acquire qualitatively new properties as a result of any interactions among the constituent systems. |
Firmware | Hardware combined with read-only software that is not easily modified. |
