There are different ways of defining the elements that make up an operating model. People, process and technology is one commonly used definition, [1] process, organization and technology is another. [2] An organization is a complex system for delivering value. An operating model breaks this system into components, showing how it works.
The reason for any new model is likely to be a new strategy or new business model or a significant failure in the performance of the existing operations for one or more stakeholders. Hence work on target operating models should be closely linked to strategy work. Form follows function; in other words target operating models follow strategy.
Example of a high-level systems architecture for a computer. A system architecture is the conceptual model that defines the structure, behavior, and views of a system. [1] 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.
Systems modeling or system modeling is the interdisciplinary study of the use of models to conceptualize and construct systems in business and IT development. [ 2 ] A common type of systems modeling is function modeling , with specific techniques such as the Functional Flow Block Diagram and IDEF0 .
A multiprocessor system is defined as "a system with more than one processor", and, more precisely, "a number of central processing units linked together to enable parallel processing to take place". [1] [2] [3] The key objective of a multiprocessor is to boost a system's execution speed. The other objectives are fault tolerance and application ...
A model of the operation of a system as a discrete sequence of events in time. Each event occurs at a particular instant in time and marks a change of state in the system. [99] Between consecutive events, no change in the system is assumed to occur; thus the simulation can directly jump in time from one event to the next.
IBM System/360 Model 50 operator's console and CPU; the operator's console is a terminal used by the operating system to communicate with the operator. The first computers in the late 1940s and 1950s were directly programmed either with plugboards or with machine code inputted on media such as punch cards , without programming languages or ...
An early example of a master/slave multiprocessor system of microprocessors is the Tandy/Radio Shack TRS-80 Model 16 desktop computer which came out in February 1982 and ran the multi-user/multi-tasking Xenix operating system, Microsoft's version of UNIX (called TRS-XENIX). The Model 16 has two microprocessors: an 8-bit Zilog Z80 CPU running at ...
