The document discusses how SharePoint and BizTalk can work together better for business process management and workflows. It describes how Business Connectivity Services (BCS) in SharePoint 2010 enables integrating external line-of-business data and applications. However, BCS has limitations for complex integrations needs. Microsoft BizTalk Server provides an enterprise service bus (ESB) that can handle more sophisticated integrations and address BCS challenges like request composition, result aggregation, and business rules. The document argues that combining BCS and the BizTalk ESB provides a manageable integration solution with good user experience.
