Workday is the modern solution that has been consistently designed in regards to user experience for employees and managers. Workday is particularly suitable as a global HCM system that can be quickly implemented for the entire workforce. Payroll and time management, on the other hand, are often still better located in an (existing) SAP HCM, as Workday does not offer payroll functionality for all countries yet. Also, to reduce complexity of the initial Workday implementation by out-scoping of local requirements. The same applies to existing interfaces, especially to local systems. These should initially continue to be connected to the SAP HCM system and then, if necessary, step-by step be migrated to Workday.
