Systems and methods are described for providing task chaining as part of modeling a business process (e.g. a BPEL process). Chained tasks maintain a reference to the previous task and during retrieval of that task, the system can append relevant information, including but not limited to task history, attachments and comments of the previous task. Task chaining can be enabled by selecting a previously completed task and marking that the current task chains the selected task. In one embodiment, tasks are chained across multiple instances of a process. Accordingly, tasks in different processes can be chained together to obtain access to the same context information and other data.
