It ran a 50 seat ERP system that managed over 1000 suppliers and 500 customers, did all invoicing, inventory/stock management, logistics and financials. In the hands of clue that is.

There is still is a lot of stuff hiding out there that works like that which is used daily and has few issues. You just don't hear about it because the people building and operating it really don't give a crap and have no enthusiasm - it's a tool to do a job. As it should be.

Sample size is irrelevant to you, the sample size.
