The Loan Origination Reference Architecture
The Loan Origination Reference Architecture shows how to build architectures that unify people, process and technology through familiar Office 2007 user interfaces. It includes an architecture framework for lending with an Office Business Application based scenario and BizTalk “MISMO” Accelerator for the loan origination process in banking. OBAs are an emerging class of business applications that connect existing line-of-business (LOB) systems with the people that use them every day through the familiar user interface of Microsoft Office, bridging the gap between how business process systems work, and how people work. OR-LOS will help customers simplify document management, increase integrated workflow, improve efficiency and ultimately lower time-to-market offering for faster turn-around and reduced cost.
