This paper presents a case study of a mortgage loan origination project using SCRUM Agile model and Business Process Management and Business Rule Management System (BPMS and BRMS). From the Waterfall model (Stage 1), a web-based self-developed had been developed using opensource frameworks: Spring and Sarasvati. But, several problems were detected and the project failed due to insufficient project management, rapid requirement changes and developer coding skills. The project was continued (Stage 2) selecting a BPMS and BRMS tool. Later, Stage 3 SCRUM was executed with proper project management and the new tool, which suited better for rapid business needs, and minimum coding. An efficient team communication and the frequent delivery of code releases increasingly contributed to the sponsor and user’s satisfaction. However, due to political influenced timeline, inexperienced project management and requirement changes, the budget exceeds and SCRUM is not favored. Nonetheless, Open-end questionnaire and interview results with core team members both business users and developers as well as software usability measurement inventory (SUMI) conducted with 14 users, it shows that SCRUM and the new tool rescue the project. Empirically, this paper demonstrates a method to evaluate the use of Agile augmented with usability measurement to Agile development community.
