I have also heard from large customers with over 300,000 employees that their projected cost savings was about $60 Million over three years. I did not get a percentage from them. But I guess it might be close to 50% in cost savings compared to an OnPremise implementation. Such cost savings combined with innovation and agility are key reasons why I believe most organizations will move their talent management applications to the cloud.
For thousands of organizations the HCM picture will look a bit like this.
