I am not an HR expert. I am certain that studying [HR Information Technology - How to Select Human Resources Information Technology](http://humanresources.about.com/od/hristechnology/a/assess_needs.htm) will help you in designing a questionnaire to ask staff for their views.

If you had searched CiteHr, you would have found a questionnaire at [https://www.citehr.com/99785-hr-gen-questinaire-hris-system.html](https://www.citehr.com/99785-hr-gen-questinaire-hris-system.html).
