Steve Hamm, The Author of "The Bangalore Tiger" has a post providing an overview of his recent discussioins with Infosys & Accenture, In the post Steve specifically covers some tools developed by both these companies which help them better deliver the services here is summary of the tools:

Infosys has a tool, InFlux, which captures a client's business requirements and transforms them into an IT plan.

The company last May started holding day-long customer innovation workshops, one-on-one with a customer, where it listens to what the customer wants to do with its IT and business processes and then tries to come up with projects where the two sides can co-create solutions for the customer.

Accentures tool is called Application Ecosystem Instrumentation, the tool allows accentures consultants to draw pictures for clients of how their business processes and underlying technologies work now, so they can spot efficiencies. They can do what-if exercises, for example sizing up the impact and investment required in adopting a particular software application.

Classic services don't scale. As you get more work, you have to put more people on the job. But with these new technologies, these companies are changing the services business model.
