Methods and apparatus are provided for developing and processing workflows that include communication tasks. A workflow is generated according to the present invention by inserting at least one communication node in the workflow. The communication node associated is with a communication task having at least one property that is resolved at run time. For example, the media type, recipient list, or timing of a communication may be resolved at run-time. A workflow generation tool is provided that generates a workflow based on (i) a user selection of at least one communication node to insert in a workflow, and (ii) a user specification of one or more properties of the communication task, wherein at least one property of the communication task is resolved at run time. At run-time, a workflow engine parses at least communication node in a workflow associated with a communication task and having at least one property that is resolved at run time.
