- Introduction to Systems Engineering
SE is a transdisciplinary approach and means to enable the realization of successful systems. Successful systems must satisfy the needs of their customers, users, and other stakeholders.
Foundations of Systems Engineering
Systems Engineering Fundamentals
3 Open System -defines elements and relationships which can be considered part of the
system and describes how these elements interact across the boundary with related elements in the
environment. The relationships among the elements of an open system can be understood as a
combination of the systems structure and behavior. The structure of a system describes a set of system
elements and the allowable relationships between them
3 Closed System –all aspects of the system exist within this boundary. This idea is useful for
abstract systems and for some theoretical system descriptions.

funding; create workflows; and make decisions) and their environment(s), to achieve business and
operational goals through a complex web of interactions distributed across geography and time
(Rebovich and White 2011).
Systems of Systems (SoS)
(1) Two or more systems that are separately defined but operate together to perform a common goal. (Checkland 1999)
(2) an assemblage of components which individually may be regarded as systems, and which possess two additional properties:
(a) Operational Independence of the Components: If the system-of-systems is disassembled into its component systems the component systems must be able to usefully operate independently. That is, the components fulfill customer-operator purposes on their own.
(b) Managerial Independence of the Components: The component systems not only can operate independently, they do operate independently. The component systems are separately acquired and integrated but maintain a continuing operational existence independent of the system-of- systems. (Maier 1998, 267-284)
(3) System‐of‐systems applies to a system‐of‐interest whose system elements are themselves systems; typically these entail large scale inter‐disciplinary problems with multiple, heterogeneous, distributed systems. (INCOSE 2012)
Systems Thinking – Systems thinking provides a very powerful approach to problem analysis that gives analyst the ability to view problems within the context of an overall system, and thereby better identify and prevent unintended negative consequences of proposed solutions (changes).
-is the process of understanding how things, regarded as systems and components of systems, influence one another within a whole. Focused on the entire system and how the parts interrelate
Representing Systems with Models
In the context of systems engineering, a model that represents a system and its environment is of
particular importance to the system engineer who must specify, design, analyze, and verify systems, as
well as share information with other stakeholders.
Purpose of a Model
Models are representations that can aid in defining, analyzing, and communicating a set of concepts.
System models are specifically developed to support analysis, specification, design, verification, and
validation of a system, as well as to communicate certain information.
