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 ...
A system architecture is the conceptual model that defines the structure, behavior, and views of a system. [1] ... or roles played by organizations or people. ...
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 ...
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.
The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
A hardware systems architect should use sketches, models, and prototypes to discuss different solutions and results with the user or system architect, engineers, and subordinate architects. An early, draft version of the user's manual is invaluable, especially in conjunction with a prototype.
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.
