Privia:

"Whether it’s compiling complex client proposals, managing work across multiple-domains and time-zones, managing pre-sales and post-sales commitments, or rapidly developing winning new products, Privia will help your organization rationalize and improve key business processes, while reducing program risks and enhancing customer satisfaction."

This workflow program is focused on deliverable and commitment management. I'm not sure many people really respect such strict processes though. It apparently integrates well with corporate e-mail and calendaring, and also uses instant messengers.
