I see quite a few (as of December) switched to new products... wondering what and how its going for you?
My thoughts so far after being into 7.5.1, yet not having it production ready yet...
1) We've had to reinstall it twice due to a few prerequisites missing in the implementation guide. We wouldn't have known about these except for having called support on other issues and them noticing it.
2) If you have users in your organization that do not have an e-mail address, it won't pull information for them from the CMDB unless you customize it through workflow (if it's even possible and not locked down).
3) The hardware requirements are ridiculous. Performance wise, it is taking around a minute for the submit incident forms to load (first time or any time it is updated through workflow). I haven't checked what all it is loading, but considering any other system I've used (including HD6) took maybe 5 seconds at most, this is not very productive.
4) The out of the box items are lacking. These include no e-mail templates, (2) rulesets (which do very little).
5) If you know nothing about workflow, and don't have training planned, you're likely to get lost. They may say that this release keeps you in ProcessManager more to set it up, but already, close to if not over half of my time has been spent in workflow.
6) There are a few bugs, a few known, a few unknown; a few with workarounds, a few with workarounds that they don't know what the upcoming MP1 update will do if you implement them, and a few without... what they all are, who knows since they're not all listed anywhere for known issues.
7) They claim that you can go through the implementation guide as a step by step... wrong! If you do, you will find a few steps that should be in a different order. If you make this claim, they claim that they did this because everyone's expectations/environment are different; however, some of the steps that were like this were base steps.
8) The interface is not very intuitive. I have already been asked by my managers to make customization after customization (some of which can't be done because there are core features that are locked down) because of this; the out of the box set up is not very end user friendly. Actually, I myself have found that sometimes I have to hunt my way to find settings that I previously accessed.
9) We had a few issues with the HelpDesk 6 involving rules, queues, and notifications being off. I had never worked with that system before (I inherited it), yet was able to do in two days what it has taken more than a couple of weeks to do in SD.
Yes, the workflow can do a lot of things, but if there's no training provided, plan for a few weeks to play around with it. If you can, hire someone to set it up.
