Handbook defines systems engineering discipline for students and professionals. Consistent with ISO/IEC/IEEE 15288:2015 standard. Provides authoritative reference for understanding SE practice
Systems engineering integrates complex systems across their lifecycle. A system is a combination of components working together to perform a function. The field combines technical and human-centered disciplines. Systems engineering requires 15-20% of total project effort
M&S uses models to develop data for managerial and technical decision making. Computer builds mathematical models containing physical model parameters. Modeling abstracts reality, simulation executes models over time. Simulation results depend on quality of underlying models
SADT was created by Douglas T. Ross in the late 1960s. It was formalized as IDEF0 in 1981. Field-tested between 1969 and 1973 with SofTech, Inc. Used in MIT APT project and US Air Force manufacturing program
IDEF0 is a function modeling methodology developed in 1970s. Part of Integrated DEFinition family for software and systems engineering. Used to represent system functions and their relationships
UML is a standardized graphical language for visualizing software systems. UML diagrams fall into structural and behavioral categories. Structural diagrams show static system parts, behavioral diagrams show functionality. UML includes 14 diagrams, seven of which are SysML-specific
