Pros
Nothing is really carved in stone at Servicenow so you can pretty much do what you want as long as you achieve your goals. Goals are only financially driven by the way. Everybody is making a lot of money which is good for overall atmosphere :-) I am not sure however that the huge focus on making a lot of money, buying expensive cars, etc is beneficial to the quality of the product...
Kontras
The ServiceNow product actually has many bugs and sometimes it seems we are just running one big cover up operation to keep this away from customers and prospects. Bug fixing takes way too long also, I am not a technician but apparently due to the infrastructure and the many customisations through scripting that customers do, upgrades become more and more difficult and cause more issues and therefore the time in between releases keeps increasing.
