My wife worked for a large law firm that decided to standardize on SAP. That's sensible - there are loads of legal practice management suites out there that are designed to cope with the peculiar demands of legal billing - so let's ignore all those and buy a product that doesn't do it, and spend millions adding customization to get what we want.

Of course the project was killed after 3/4 years and millions spent.

A good thing for SAP that in the large firms they target, mediocrity floats upwards!
