      For each business process in the business process list create a candidate orchestrated service.

      Refine the business process models based on newly identified service candidates.

      Steps

      Identify the single task that starts the business process.

      Example: An orchestrated service named "AccountOpeningProcessService" might have an initiating task named "openAccount."
