We had very close contact all the way through with Titan, over a long period. Titan were always realistic with the target launch date, and we put it back twice. Many trial runs on Accounts and database extracts, and the data was all “live” on the test system a month before the actual changeover.
It all happened over a weekend, and most staff were on site. The Titan team wanted to ensure that come Monday morning, business could be transacted, and it did. Training carried on and we covered some areas over and over until individuals or teams had enough to be able to work with.
I think it went pretty smoothly, and whilst there were one or two “unforeseen” issues, the Titan team rectified these, and have no doubt learned from the experience.
In addition to the training, Titan has an extensive library of HELP SHEETS built in to the system. These are NOT the usual text only type instructions. These are screen shots, and with the system available to us, we were able to SELF-TEACH, to a degree. In reality, this was a “warm up”, but it helped a lot of us who explored.
