An enterprise includes a number of functions and operations such as purchasing, manufacturing, marketing, finance, engineering, and research and development. The enterprise of interest are those corporate functions and operations necessary to manufacture current and potential future variants of a product.
Enterprise architecture framework
The term "enterprise model" is used in industry to represent differing enterprise representations, with no real standardized definition. For example, the use of networked computers to trigger and receive replacement orders along a material supply chain is an example of how information technology is used to coordinate manufacturing operations within an enterprise.
The basic idea of enterprise modelling according to Ulrich Frank  is "to offer different views on an enterprise, thereby providing a medium to foster dialogues between various stakeholders - both in academia and in practice. For this purpose they include abstractions suitable for strategic planning , organisational re- design and software engineering. The views should complement each other and thereby foster a better understanding of complex systems by systematic abstractions.
The views should be generic in the sense that they can be applied to any enterprise. At the same time they should offer abstractions that help with designing information systems which are well integrated with a company's long term strategy and its organisation. Hence, enterprise models can be regarded as the conceptual infrastructure that support a high level of integration.
Enterprise modelling has its roots in systems modelling and especially information systems modelling. One of the earliest pioneering works in modelling information systems was done by Young and Kent ,   who argued for "a precise and abstract way of specifying the informational and time characteristics of a data processing problem".
They wanted to create "a notation that should enable the analyst to organize the problem around any piece of hardware ". Their work was a first effort to create an abstract specification and invariant basis for designing different alternative implementations using different hardware components. A next step in IS modelling was taken by CODASYL , an IT industry consortium formed in , who essentially aimed at the same thing as Young and Kent: the development of "a proper structure for machine independent problem definition language, at the system level of data processing".
This led to the development of a specific IS information algebra. The first methods dealing with enterprise modelling emerged in the s. Ross , the one concentrate on the information view and the other on the function view of business entities. Specific methods for enterprise modelling in the context of Computer Integrated Manufacturing appeared in the early s.
Enterprise Architecture at Work
An enterprise model is a representation of the structure, activities, processes, information, resources, people, behavior, goals, and constraints of a business, government, or other enterprises. According to Fox and Gruninger from "a design perspective, an enterprise model should provide the language used to explicitly define an enterprise From an operations perspective, the enterprise model must be able to represent what is planned, what might happen, and what has happened. It must supply the information and knowledge necessary to support the operations of the enterprise, whether they be performed by hand or machine.
Beer's model differs from others in that the VSM is recursive, not hierarchical: "In a recursive organizational structure, any viable system contains, and is contained in, a viable system. Function modelling in systems engineering is a structured representation of the functions , activities or processes within the modelled system or subject area. A function model, also called an activity model or process model , is a graphical representation of an enterprise 's function within a defined scope.
The purpose of the function model are to describe the functions and processes, assist with discovery of information needs, help identify opportunities, and establish a basis for determining product and service costs. A functional perspectives is one or more perspectives possible in process modelling.
Other perspectives possible are for example behavioural, organisational or informational. A functional modelling perspective concentrates on describing the dynamic process. The main concept in this modelling perspective is the process, this could be a function, transformation, activity, action, task etc. A well-known example of a modelling language employing this perspective is data flow diagrams. The perspective uses four symbols to describe a process, these being:. Now, with these symbols, a process can be represented as a network of these symbols.
This decomposed process is a DFD, data flow diagram. Data modelling is the process of creating a data model by applying formal data model descriptions using data modelling techniques. Data modelling is a technique for defining business requirements for a database. It is sometimes called database modelling because a data model is eventually implemented in a database. The figure illustrates the way data models are developed and used today. A conceptual data model is developed based on the data requirements for the application that is being developed, perhaps in the context of an activity model.
The data model will normally consist of entity types, attributes, relationships, integrity rules, and the definitions of those objects. This is then used as the start point for interface or database design. Business process modelling , not to be confused with the wider Business Process Management BPM discipline, is the activity of representing processes of an enterprise, so that the current "as is" process may be analyzed and improved in future "to be".
Business process modelling is typically performed by business analysts and managers who are seeking to improve process efficiency and quality. The process improvements identified by business process modelling may or may not require Information Technology involvement, although that is a common driver for the need to model a business process, by creating a process master. Use impact analysis to trace proposed changes to original requirements. Build the right system. Enterprise Architect's built-in requirements management features can be used to:. Enterprise Architect users agree - Enterprise Architect is a spectacularly fast performer, loading extremely large models in seconds.
Featuring a high-performance model repository, Enterprise Architect easily accommodates large teams sharing the same view of the enterprise. With tightly integrated version control capabilities, and deployable cloud-based servers, Enterprise Architect also allows globally distributed teams to collaborate effectively on shared projects. A wealth of specially crafted patterns and re-usable model structures across multiple modeling domains and languages will fast track your design work and help you deliver accurate and stunning models that leverage a strong and proven foundation.
Perspective based modeling reduces noise and simplifies the workspace. Turn down the noise and focus in on one modeling task at a time.
Concentrate on Business Analysis or Strategy or Software Design or Systems engineering while pushing other technologies and tools into the background. An essential tool for staying "on track".
