A system and method for facilitating execution of a portion of a process via a subprocess. An example method includes encapsulating process logic of a portion of a parent process via the subprocess, wherein the parent process is encoded via a business process language characterized by process lifecycle management functionality; using an instance of a call activity in a scope of the parent process or subprocess to activate the subprocess, yielding a called subprocess in response thereto; and employing a business process runtime engine to adjust a scope of the subprocess to inherit the scope of the process used to call the subprocess, thereby enabling the process lifecycle management functionality to govern a lifecycle of the subprocess. In a more specific embodiment, the business process language includes standard Business Prosecution Execution Language (BPEL); the parent process represents a business process; and the subprocess includes a standalone subprocess.
