Measuring the Effectiveness of HRIS
Regarding measuring the effectiveness of HRIS, it depends on the business and user expectations. Firstly, is it purpose-built for the business, and does it cover all requirements? Is the system scalable and configurable to the evolving business needs? Is the developer/vendor flexible to accommodate future needs? These are some of the key factors you would consider even at the initial stage of choosing the system. Once you have identified the business requirements, then you can have measures to evaluate how well those requirements are met and delivered. One of the primary business requirements is to have consistent, accurate data about employees in one place. Then, once you have the data, instead of just populating data in a report, is the system capable of any analytics? So the first part of your analysis should be about system capability and functionalities.
User Experience and Data Credibility
The second part, I believe, should be about user experience. Even the best system in the world is only as good as how well it's used. If the system is not user-friendly and easy to use, it will impact the user experience, and the result is the credibility of data and completeness of data will suffer. So in this regard, your measures will be focused on the completeness of data, timeliness of data, and accuracy of data, etc. If this HRIS includes an Employee Self-service, you may also check how often people log in to use the system and update their information.
These are just the very basics, and it all depends on the industry, business, and other factors.
Hope this will give you at least a start, and I am sure others will contribute to this thread.
