If you want anything in specific let me know
The Business Process Testing model is role-based, allowing non-technical Subject Matter Experts (working in Quality Center) to collaborate effectively with Automation Engineers (working in QuickTest Professional). Subject Matter Experts define and document business processes, business components, and business process tests, while Automation Engineers define the required resources and settings, such as shared object repositories, function libraries, and recovery scenarios. Together, they can build, data-drive, document, and run business process tests, without requiring programming knowledge on the part of the Subject Matter Expert.
