The Semantics of Business Vocabulary and Business Rules specification (SBVR), approved as an interim specification of the OMG, divides business rules into structural rules which express necessities and supplement definitions, and operative rules which express obligations and business conduct. How Business Rules Define and Simplify Processes Therefore, business rules guide and constrain business processes, not only the calculations and validations but also the sequence and timing of activities. Which process in Figure 3 is compliant with the rules? What if the rules change? Indeed, the process will have to change.īusiness rules define the semantics and constraints of business concepts, the reaction to business events, the constraints and preconditions on activities, the rights and obligations of actors, etc. Order policy: "We can only ship the goods after we have received an official corresponding order." Defining the Processīut what about the rules based on the following order policy? The process is now reduced to its essence and not subject to major or minor changes in policies, applicant types, calculations, etc.įigure 2. Isolating applicant type rules.įigure 2 is even more flexible. As indicated in Figure 1, separating the rules that define the applicant type (the know) from the process (the flow) creates more flexible processes.įigure 1. ![]() It is well known that hard-coding the decision logic of calculations, inferences, and decision points into process models is not flexible. In particular, it is argued that flexible business process models require business rules as a declarative formalism to capture the semantics of policy and regulation. The issue here is the role of business rule modeling in achieving business process flexibility. When modeling business processes, we implicitly have the policies and regulations in mind, but usually little attention is paid to avoiding the hard-coding of these underlying rules directly into process models. In this way, changes in policies and regulations can be traced back to the business processes where they are to be enforced, thereby enhancing flexibility and compliance. ![]() The key to business rules is that they make the knowledge about implicitly present policies and regulations explicitly traceable. Whenever the rules change, processes may have to change accordingly. This compromises the business' ability to rapidly incorporate business policy change and regulatory change in the business processes. Unfortunately, systems often make business processes more rigid than flexible by hard-coding rules and processes. Information Systems must flexibly support business processes that at the same time are compliant to the (intra-organizational) business policies and procedures and to the inter-organizational regulations and protocols the business has to observe. In this article we show how business rule modeling plays an important role in achieving business process flexibility - not just by separating the decision logic from the business process, but also by using business rules as the starting point to generate less complex and more flexible business process models by reducing them to their essence.

Attention affects the mean neuronal firing rate as well as its variability and correlation across neurons. Over the past few years, insights on the neural circuits and mechanisms of bottom-up and top-down attention have been gained through neurophysiological experiments. Attention can be categorized into two distinct functions: bottom-up attention, referring to attentional guidance purely by externally driven factors to stimuli that are salient because of their inherent properties relative to the background and top-down attention, referring to internal guidance of attention based on prior knowledge, willful plans, and current goals. ![]() The brain is limited in its capacity to process all sensory stimuli present in the physical world at any point in time and relies instead on the cognitive process of attention to focus neural resources according to the contingencies of the moment.
