I'd advise others to map their processes out before starting with the solution.

Hornbill has recently generated a new version of its product and it meets some of the requirements that we would have been looking for. It's a bit more scalable, a bit more responsive to a customer-focused model for support, and they've improved a lot of things like process flow and self-service.

In terms of rating the solution, it's difficult to grade. It really depends on the size of the organization that's trying to use it as that tool. One of the reasons why we're looking to shift is because we've grown quite a bit over the years that we've had it, which makes it difficult for it to meet our demands. However, for an organization the size of what we were when we started our journey with it, I'd rate it ten out of ten. Where we are now, with our company size and needs, I'd rate it six out of ten. 

Do as much of the work and customizations yourself as you can. Learn as much as you can about the product.
