    • An object-focused workflow system for processing a received object in accordance with a declarative workflow specification. The specification includes modules and attributes, where module execution results in the evaluation of attributes, and may include the initiation of a side-effect action performed by an external component. Whether modules are to be executed for a particular received object is determined by associated enabling conditions. Attributes may be evaluated in accordance with computation rules and a combining policy, where the computation rules specify how values are to be contributed to an attribute, and the combining policy indicates how those contributed values are combined in order to assign a value to the attribute. Tasks in the workflow system may be executed eagerly in order to improve the performance of the workflow system. The eager evaluation of tasks includes the determination of whether such tasks are eligible for eager evaluation, and whether the tasks are unneeded or necessary for the processing of the received event. Workflows which satisfy described design properties allow for improved algorithms for the determination of the whether tasks are eligible, eager, and/or necessary. A graphical user interface is provided for displaying a representation of the evaluation status of the modules and attributes during workflow execution.

    • System and method including dynamic differential treatment in workflows and contact flow

    • Computer and telecommunication systems employing workflow (contact flow) processes are enhanced by employing dynamic random differential treatment of so-called instances (contacts) entering the workflow (contact flow). This is realized, for example, by associating a prescribed distinguishing function with the workflow (contact flow), and to use a value given by this prescribed distinguishing function in one or more decisions relating to how the object instance (contact) should be processed. Each decision is essentially a choice between two or more paths in a workflow (contact flow), or a choice between two or more workflows (contact flows). For example, the prescribed distinguishing function could associate a distinguishing value having an integer value between 1 and 100 with object instances (contacts), and a selection function for making a decision to use one or more of a plurality of workflows (contact flows) is related to a prescribed parameter “x” that has a value from 0 to 100. For example, each object instance (contact) with a prescribed distinguishing value≦x is routed to a first of the plurality of possible treatments and each object instance (contact) with distinguishing value>x is routed to at least another of the plurality of possible treatments. Additionally, dynamic control is utilized over the parameters employed by the selection function that control whether object instances (contacts) are routed to the first treatment or to some other treatment. For the preceding example, this is accomplished by permitting dynamic control over the value of prescribed parameter x. This dynamic control is effected either manually or automatically. In a particular embodiment of the invention, dynamically controlled differentiation is realized by associating a random number (or other randomly chosen value) with each object instance (contact), and to use this random number in one or more decisions relating to how the object instance (contact) should be processed. That is, a randomized differentiator is utilized as the dynamically controlled differentiator.
