Who is the opinion leader in HR and HR information systems?
The CIPD in most countries will serve as a guide to most HR subject/issues and as thought leaders, they conduct a lot of studies and in partnership with businesses and Universities. If there is any particular issue you wnat to explore, then by all means try and contact the CIPD in your country (The Chartered Institute of Personnel & Development). With regards to HRIS, there are different manufacturers and systems depending on what features you require and what information, data and MI that you wish to maintain, generate and use. Again the CIPD provides a guide and things to consider before purchasing a system plus you can request demos from the providers to ensure it meets your requirement and need.
