“In enterprise modelling, we want to define the actions performed within an enterprise, and define constraints for plans and schedules which are constructed to satisfy the goals of the enterprise. This leads to the following set of informal competency questions:”

—  Mark S. Fox

Temporal projection - Given a set of actions that occur at different points in the future, what are the properties of resources and activities at arbitrary points in time?
Planning and scheduling - what sequence of activities must be completed to achieve some goal? At what times must these activities be initiated and terminated?
Execution monitoring and external events - What are the effects of the occurrence of external and unexpected events (such as machine breakdown or the unavailability of resources) on a plan or schedule?
Time-based competition - we want to design an enterprise that minimizes the cycle time for a product. This is essentially the task of finding a minimum duration plan that minimizes action occurrences and maximizes concurrency of activities.

“An enterprise must be viewed from several perspectives if it is to be fully described and understood (Barnett 1994; ESPIRIT Consortium AMICE 1991). Previous work in the development of architectures by the Automation & Robotics Research Institute (Presley et al. 1993) describes a five view approach. The Business Rule (or Information) View defines the entities managed by the enterprise and the rules governing their relationships and interactions. The Activity View defines the functions performed by the enterprise (what is done) while the Business Process View defines a time sequenced set of processes (how it is done). The resources and capabilities managed by the enterprise are defined in a Resource View. Finally, the Organization View is used to define how the enterprise organizes itself and the set of constraints and rules governing how it manages itself and its processes.”

“Information Engineering is the application of an interlocking set of formal techniques for the planning, analysis, design, and construction of information systems on the enterprise wide basis or across a major sector of the enterprise.”

“An enterprise architecture can be thought of as a "blueprint" or "picture" which assists in the design of an enterprise. The enterprise architecture must define three things. First, what are the activities that an enterprise performs? Second, how should these activities be performed? And finally, how should the enterprise be constructed? Consequently, the architecture being developed will identify the essential processes performed by a virtual company, how the virtual company and the agile enterprises involved in the virtual company will perform these processes, and include a methodology for the rapid reconfiguration of the virtual enterprise.”

“Information engineering has been defined with the reference to automated techniques as follows: An interlocking set of automated techniques in which enterprise models, data models and process models are built up in a comprehensive knowledge-base and are used to create and maintain data-processing systems.”

“Strategy can be defined as the determination of the long-term goals and objectives of an enterprise, and the adoption of courses of action and the allocation of resources necessary for carrying out these goals”

“As information systems play a more active role in the management and operations of an enterprise, the demands on these systems have also increased. Departing from their traditional role as simple repositories of data, information systems must now provide more sophisticated support to manual and automated decision making; they must not only answer queries with what is explicitly represented in their Enterprise Model, but must be able to answer queries with what is implied by the model. The goal of the TOVE Enterprise Modelling project is to create the next generation Enterprise Model, a Common Sense Enterprise Model. By common sense we mean that an Enterprise Model has the ability to deduce answers to queries that require relatively shallow knowledge of the domain.”

“CIMOSA provides a Reference Architecture (known as the CIMOSA cube) from which particular enterprise architectures can be derived. This Reference Architecture and the associated enterprise modelling framework are based on a set of modelling constructs, or generic building blocks, which altogether form the CIMOSA modelling languages.”

“Enterprise Engineering is defined as that body of knowledge, principles, and practices having to do with the analysis, design, implementation and operation of an enterprise. In a continually changing and unpredictable competitive environment, the Enterprise Engineer addresses a fundamental question: “how to design and improve all elements associated with the total enterprise through the use of engineering and analysis methods and tools to more effectively achieve its goals and objectives”…”

“Although many popular information systems planning methodologies, design approaches, and various tools and techniques do not preclude or are not inconsistent with enterprise-level analysis, few of them explicitly address or attempt to define enterprise architectures. Some examples of such popular offerings include”

From an historical perspective, BSP and BICS likely will be looked back on as primitive attempts to take an explicit, enterprise-level architectural approach to information systems.

“The Generic Enterprise Reference Architecture and Methodology is about those methods, models and tools which are needed to build the integrated enterprise. The architecture is generic because it applies to most, potentially all types of enterprise. The coverage of the framework spans Products, Enterprises, Enterprise Integration and Strategic Enterprise Management, with the emphasis being on the middle two. The proposal for the architecture follows the architecture itself improving the quality of the presentation and of the outcome. De nitions of Generic Enterprise Reference Architecture, Enterprise Engineering/ Integration Methodology, Enterprise Modelling Languages, Enterprise Models, and Enterprise Modules are given. It is proposed how the above could be developed on the basis of previously analysed architectures (and other results too), such as the Purdue Enterprise Reference Architecture, the GRAI Integrated Methodology, CIM-OSA, and TOVIE.”
