Basically this research is to discuss how successfully select and implement HRIS at organization that have large-scale and complex condition. Also understand the process implementation included sticking to a timeline. Bank XYZ is a case study in this research, the reason to implement HRIS is because in human resource management division was previously carried out in seven systems that were not integrated (Time Management, Performance Management, Travel Management, Learning Management System, Personnel Administration, Organization Management and Payroll/Tax), so interface and scheduler were needed to stream data. As a result, data could not be accessed in real time in other applications that needed it. The large-scale organization has an issue in sticking to a timeline, because Bank XYZ has a large scale and complex organizational conditions, we can learn from Bank XYZ how the process implementation HRIS in large-scale company to that issue. From the results of document analysis and interviews, HRIS implementation process in Bank XYZ have been done in several phases based on application software package model methodology including the definition, selection, development and implementation and operation phases. In addition to the planned implementation phase change management was needed in this HRIS implementation process, so that implementation can be carried out in accordance with the specified time. Then for large-scale and complex organization can learn how to implement HRIS right into the timeline based on this research.
