I'm sure big companies love SAP. The killer feature is that it works. There is no other comparable software. You will never run out of guys who can maintain the system. The user interface is complicated by design; it's reusable and you can check/see every value multiple times before it is finally saved (wrong data leads to wasted time & wasted money); and finally it's easier for the consultants to implement. And in my opinion the most important fact is that the customers of SAP are top-level executives and so on and not the end-user.

I've seen big global companies spend months without being able to bill and/or collect money because of SAP problems. SAP is basically a cover a%$ for terrible decision makers, i.e., a marketing play. No?

There will also, often, be multiple integrated components of the suite so you have buy-in across multiple points (finance, inventory, sales, etc.) of the enterprise and the software becomes somewhat entrenched.
