The Architecture Strategy Team has just released an Office Business Applications Reference Application Pack for Loan Origination Systems (OR-LOS) that leverages SharePoint, BizTalk Orchestrations, BizTalk Business Rules Engine, WF Workflows, and Office Clients to automate a Loan Origination process spanning multiple human and system participants. Mike Walker has posted all the details including whitepapers, an introductory video, and the sample bits (including a new MISMO accelerator) on his blog. Attached is a pic from one of the whitepapers that shows the high level view of the process.
Also, Mike and the Financial Services team have some more great content on building OBAs on top of an ESB here. Be sure to check out this paper. It has tons of BizTalk (even though it’s not in the title ;).
