One of the learning models currently deemed relevant to the current learning process is project-based learning; using this method, students are expected to be able to develop a product based on lecture activities completed in collaboration with group members. In order to maintain the objectivity of assessment in this learning paradigm, the final outcome of a learning process must be evaluated. An integrated information system is a solution that can meet the requirements of an evaluation procedure. This integrated information system is also a solution that eliminates the need for all appraisers to assemble in the same location, allows external appraisers, such as those from the industry and practitioners, to view product quality more objectively, and facilitates dialogue throughout the assessment process. This study's information system will be constructed using web-based and mobile computing to enable access to applications regardless of location or geography.This research has produced an accessible and dependable architecture for an integrated information system supporting collaborative assessment processes for project-based learning..
