The preparation of the RKA report starts from collecting proposals from each work unit to the approval process by the Board of Directors on the proposals of each work unit. In an effort to streamline business processes that occur, analyze data needs, processes and also actors involved in organizational activities, an Information System is needed to streamline processes that occur, collect all required data and create proposal reports.
