Public services in the digital era require government agencies to optimally utilize information technology. In carrying out its services, the Social Affairs Office of Ciamis Regency has not been supported by an integrated information system, resulting in constraints in data management and service effectiveness to the community. This research aims to develop an information systems strategic plan using the Ward and Peppard method to improve service performance at the Social Affairs Office of Ciamis Regency, as well as to produce an application portfolio and information system strategy recommendations aligned with organizational goals. This research uses the Ward and Peppard method, which includes business environment analysis and internal and external IS/IT analysis using the tools SWOT, Value Chain, Critical Success Factors (CSF), PEST, and the McFarlan Strategic Grid. Data were collected through literature study, observation, interviews, and questionnaires distributed to 15 respondents using a four-point Likert scale. This research produced an information systems strategic plan comprising an IS business strategy to support service needs, an IT strategy involving the development of hardware, software, network infrastructure, system integration, and data security, and an IS/IT management strategy covering governance, human resource competency development, and IS/IT investment management. In addition, the research produced an application portfolio consisting of 21 proposed information systems mapped into the McFarlan Strategic Grid, comprising 5 Strategic applications, 7 Key Operational applications, 4 Support applications, and 5 High Potential applications, accompanied by a five-year development roadmap (2026-2030) to guide the Social Affairs Office of Ciamis Regency in supporting the digital transformation of social services.
