What do you mean by a system?
WHAT IS SYSTEM ENGINEERING System is collection of inter-related components. inter-
Engineering means designing of complex objectives.
Therefore SYSTEM ENGINEERING is defined as collection of inter-related components for designing of intercomplex objectives & then to achieve that objectives. It denotes different things to different people.
The concept of System Engineering was introduced in 1940 at BELLS Laboratory.
FEATURES1. System engineering is helpful in designing, implementing & maintaining socio-technical sociosystems. 2. System engineering is concerned with the services provided by the system. 3. System engineering process includes specification integration & testing.

Systems Engineering on the basis of techniquesTechnical computer-based system engineering computer Engineering that include hardware and software but where the operators and operational processes are not normally considered to be part of the system. SocioSocio-technical system engineering Engineering that include technical systems but also operational processes and people who use and interact with the technical system. Socio-technical Sociosystems are governed by organisational policies and rules.9
OBJECTIVES To explain what a socio-technical system is and the sociodistinction between this and a computer-based system. computer To introduce the concept of emergent system properties. To explain system engineering process. To explain system integration.
What The Emergent properties are?Emergent system properties are the properties of the system that depend upon the system components & their relationship. It can be only accessed & measured once while integrating the components in the system.
Give the examples of EMERGENT PROPERTIES.
EXAMPLES OF EMERGENT PROPERTIES
Types of emergent properties Functional emergent properties These appear when all the parts of a system work together to achieve some objective. Non-functional emergent properties NonThese relate to the behaviour of the system in its operational environment.
The process of putting hardware, software & people together is called system integration.
System Engineering processProcess of system engineering completes in 3 steps. 1. specification 2. integration 3. testing
It means setting up of the objectives.
In this step, the actual results are matched with the expected results. If both the results are matched then the objectives are said to be achieved. If it does not match then the deviations are to be found.

Attracting and developing talented system engineers. Establishing Institutional system engineering mechanisms. Managing the right balance of investments in institutional and project developed systems engineering capabilities.
