Very large, highly complex systems may include multiple architects, in which case the architects work together to integrate their subsystems or aspects, and respond to a chief architect responsible for the entire system. In general, the role of the architect is to act as a mediator between the users and the engineers, reconciling the users ...
An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the system. A system architecture can consist of system components and the sub-systems developed, that will work together to implement the overall system. There have been efforts to ...
Enterprise architecture (EA) is a mechanism for understanding all aspects of the organization, and planning for change. Those aspects include business transformation, business process rationalization, business or capability-driven solution development, application rationalization, transformation of IT to the cloud, server consolidation, service management and deployment, building systems of ...
Software architecture is the set of structures needed to reason about a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations.
QFD house of quality for enterprise product development processes. The term systems engineering can be traced back to Bell Telephone Laboratories in the 1940s. [1] The need to identify and manipulate the properties of a system as a whole, which in complex engineering projects may greatly differ from the sum of the parts' properties, motivated various industries, especially those developing ...
Software architecture and, subsequently, software architects inherently deal with uncertainties. It is the software architect's job to decide the size of architectural components, which can significantly influence a system's outcomes, both positively and negatively.
The TEAF Matrix of Views and Perspectives.. A view model or viewpoints framework in systems engineering, software engineering, and enterprise engineering is a framework which defines a coherent set of views to be used in the construction of a system architecture, software architecture, or enterprise architecture.
In the contexts of software architecture, service-orientation and service-oriented architecture, the term service refers to a software functionality, or a set of software functionalities (such as the retrieval of specified information or the execution of a set of operations) with a purpose that different clients can reuse for different purposes, together with the policies that should control ...
