Dinas Perpustakaan dan Kearsipan Kota Surabaya (DISPUSIP) is one of the Surabaya city government institutions whose role is to provide and manage public service facilities in the library and archives sector in the City of Surabaya. DISPUSIP has an IT Team that manages information technology including the development of Management Information Systems (MIS). In working on MIS development, the DISPUSIP IT Team experienced problems related to the division of job desks between members and the MIS work flow was unclear and undocumented because there were no procedures and documentation for MIS development activities. Therefore, MIS development governance is needed in the form of a Standard Operating Procedure (SOP) to manage MIS development activities. The preparation of SOPs in this thesis uses the gap analysis method to determine the gap between current conditions and ideal conditions. Current conditions were obtained from interviews and observations, while ideal conditions were obtained from activities in the System Development Life Cycle (SDLC), the COBIT 5 domain BAI03 framework, and ITIL v3 change management. The output produced from this thesis is a MIS development SOP document which consists of 5 procedures, namely: New MIS Planning SOP, New MIS Analysis SOP, New MIS Design SOP, New MIS Implementation SOP, and MIS Module Addition SOP verified using the interview method and validated with SOP test simulations to find out whether the SOP is appropriate.
