The document discusses system engineering and defines key concepts. System engineering focuses on designing complex engineering projects by defining customer needs early and documenting required functionality. It uses a waterfall model with little iteration between phases due to hardware costs. System engineering involves interaction between different engineering disciplines that require negotiation due to different vocabularies. The system engineering process includes stating problems, investigating alternatives, modeling the system, integrating elements, launching the system, and assessing performance.

All aspects of computer based systems development including hardware and software process engineering. Usually use Waterfall model Little scope for iteration between phases because hardware changes are very expensive. Software may have to compensate for hardware problems.
Much scope for misunderstanding here. Different disciplines use a different vocabulary and much negotiation is required. Engineers may have personal agendas to fulfill.
System Definition Simply known as functional unit. Executes user written programs Performs user designated manipulation Includes arithmetic logic operations Use common storage access. associated softwares
System engineering focuses on how complex engineering projects should be designed and managed. Define customer needs and required functionality early in the development life cycle, documenting.
System engineering process SIMILAR: State the problem(customer needs) Investigate alternatives Model the system Integrate (bringing elements together) Launch the system (output) Assess performance (evaluation criteria) Re-evaluation
System engineering
Requirements System definition decommissioning System System design evolution Sub system System development installation System integration
Interaction between engineering: All major engg integration Bioinformatics: Biotechnology Information technology etc
System engineering hierarchy Model: Simplified representation of a system. Simulation Computerized version of a model Modeling and simulation is a discipline for developing a level of understanding of the interaction of the parts of a system.
Hierarchy World view Public health care, e governance trade and commerce, banking & finance. Domain view Concentrate on specific domain Education College, school, etc Element view Focuses on sub domain(Admission,exams,etc) Detailed view (internal marks, university, internal)
Modeling the system Explains how the system is working. Elements of system modeling: Inputs Processes Outcomes.
