SaaS provider Workday extends HR business processes to iPhone, mobile tier
For busy managers flooded with expense report sign-offs and hiring and firing minutiae, the mobile access can be a godsend. It prevents slowed up processes, and also prevents the overloaded email in-box. Making SaaS apps reach the mobile tier -- but in an appropriate way that recognizes the use requirements for "on the go" work -- will become a general business requirement, I expect.
