There surely are. They don't, however, have the name recognition, the comparative availability of people who know how to deal with it, the ecosystem of vendors to sell you extensions, or, yeah, the sales function to push it at larger companies.

ServiceNow is big because everybody involved is incentivized to help make it big.

And FWIW, at my very very large company, it isn't even in the top 5 of shitty systems I have to deal with. ServiceNow at least works.

No, there isn’t. They all have pros and cons but none overall are “better”. ServiceNow is for large orgs with independent departments who need to use it differently. There’s BMC/Remedy but it’s just as convoluted and bad. Also Clarity.

There are many that are better at one one or two specific functions, sure. But none that have all the added features a large mature org would need.

Comparing remedy and ServiceNow is a bit like comparing cable television with Netflix.

So an improvement?
