“…Events can be defined as 'indivisible atomic units of action, with no duration, that occur in the real world, and affect at least one business entity' [20]. Although, event modelling is a quite complex area, and one can identify a wide variety of event types, we consider sufficient to refer to distinct business 'events' that trigger the execution of 'activities', without analysing them any further.…”

“…A rule's "operational WHEN part" is used for storing the business "event" that triggers its execution. Events have been defined as "indivisible atomic units of action, with no duration, that occur in the real world, and affect at least one business entity" (Snoeck and Poels, 2000). Although, event modelling is a quite complex area, and one can identify a wide variety of event types, we consider sufficient to refer to distinct business "events" that trigger the execution of "activities", without analysing them any further.…”

Purpose-In this paper we present a roadmap for the elicitation of business rules based on different stakeholders' perspectives, in order to facilitate the processes of structuring, organizing and expressing business tactic and policy in a way that it is close to the business milieu and stakeholders' viewpoints. Design/methodology/approach-This paper has derived from a combined research practice. Initially, the development of a roadmap for understanding different stakeholders' perspectives and for identifying their views on business tactics and policies was based on well-grounded work on enterprise goal modelling, combined with a theoretical study of business rule-related concepts. The outcome of this work was tested against a real business case dealing with the development of an electronic procurement system in the prefabricated construction sector. Findings-As a conclusion, the paper put forward a comprehensive methodological framework for dealing with rule-intensive projects. The proposed roadmap can help IT practitioners in collecting and organizing business rule statements that apply within a particular organization, either towards the implementation of change on a business level, or in the context of specifying the (existing or future) functionality of supporting information systems (IS). Research limitations/implications-The rule roadmap presented here has been coupled with a modelling approach for expressing rules in a structured, consistent manner and for organizing them in a rule repository. Future work includes the extension of this approach to cover design and implementation as part of rule-centric information systems engineering. Practical implications-Therefore, the overall contribution of this work relates to the provision of guidance for identifying business policy and tactics at an intentional level (through the investigation of the rationale behind them) and for transforming relevant models to the operational level, where business rules are linked to business processes, information and systems. Originality/value-Although the business rule concept has been examined from different points of view over the past years, the paper attempts to bridge the gap between approaches that see rules as extensions of business goals, other approaches that consider rules as limitations on the way business activities are performed, and finally, approaches according to which rules constrain the creation, modification and deletion of information entities.

“…In [16,17] it is shown that events can also be a starting point in OOA of requirements for generating class diagrams. Events have also been used in conceptual modeling of domain [20], dynamic and activity modeling of applications [21À23] and business process modeling [24,25]. GUI based applications testing have also used concept of events [26À28].…”

The event based paradigm has gathered momentum as witnessed by current efforts in areas ranging from event driven architectures, complex event processing, and business process management and modeling to grid computing, web services notifications, event stream processing and message-oriented middleware. The increasing popularity of event based systems has opened new challenging issues for them. One such issue is measuring complexity of these systems. A well-developed system should be maintainable, pluggable, scalable and less complex. In this paper, an event based approach is proposed to derive software metrics for measuring system complexity. Events taking place in a system are documented using the proposed event template. An event-flow model is constructed from event templates. The eventflow model of an event based system is represented as an event-flow graph. The proposed eventflow complexity metric for analysis model is derived from an event-flow graph. The metric has also been evaluated in terms of Weyuker's properties. Results of evaluation show that it satisfies 8 out of 9 Weyuker's properties. A prototype tool is also developed to automatically generate event interdependency matrices and compute absolute and relative complexity of an entire system. The proposed technique can be very effective especially for real time systems where lots of events take place.
