System Engineering System engineering: Software engineering occurs as a consequence of a process. System engineering focuses on: - system and its elements, including hardware, software, … - product, service, technology System engineering process is called information engineering when the context of the engineering work focuses on a business enterprise. Product engineering focuses on product construction. System engineering encompasses: - a collection of top-down and bottom-up methods to navigate the hierarchy in Figure 10.2

System Modeling System engineering is a modeling process. The created models: - define the process - represent the process behavior - define both exogenous and endogenous input to the model - represent all linkages Considering factors for creating models: - assumptions - simplifications - limitations, such as hardware limitations - constraints, such as computation constraints - preferences (solutions, architecture, . .)

Information Engineering: An Overview Information engineering (IE) - define architectures that will enable a business to use information effectively. Three different architectures: - data architecture -> provides a framework about the business information - application architecture -> encompasses the elements in a system. - technology infrastructure -> provides the foundation for the data and application architecture. Information strategy planning (ISP) --> world view
