Barangays are the smallest yet the most essential units of the government. The government cascades its services through its officials. However, due to the increasing population, quality of service, especially in handling records and documents declines. After a thorough site investigation and series of surveys an integrated “Document Management System” is proposed to alleviate these problems and Barangay Paligui in Apalit, Pampanga was chosen to be the model. Using Kanban Agile Methodology and extensive reviews of literature, the DMS, an open source system was conceptualized whose primary aim is to provide a centralized document management system that can be accessed by any barangay officials using their office desktop computers and mobile phones. It utilizes OwnCloud as the infrastructure for securing, storing, and sharing the files and a customized interface for users is written in HTML, CSS, JavaScript and PHP. The users evaluated the system and found to be useful and accepted for use.
