ESS Support Model

As part of our ESS implementation we are trying to develop a support model post go-live. We would like some information/statistics from those that have gone live with ESS.

What kind of support model did you implement? (When an Employee makes a mistake in creating or updating their information on-line ? - Who was responsible for cleaning the data ? Who supported the employee through the process of correcting the data ?)

Any statistics on the percent of error or calls for support from employees would be great.

Thanks
