Built an automated credit decision support system for a major financial services institution that used workflows. We needed masses of legacy data systems integration, rule based descisions and human task coordination. This system was built with Microsoft's Biztalk around 2006. It performed very well in production, but Biztalk had quite a few gotchas that needed to be creatively worked around in development.
