My good old friend from Microsoft Corp, Vittorio Bertocci, has always been a strong supporter and advocate in helping quite a few of our enterprises here in Singapore to scale up and implement cool projects on Windows CardSpace, Windows Communication Foundation and Windows Workflow Foundation. One of which is ST Electronics (Info-Software Systems) Pte Ltd, you can find a local case study here. The other one is Changi General Hospital. Vittorio has written a nice blog on this, take a look here.
