+- Brief Reflection:
+  Before taking the agile development class, we primarily focused on developing our own game, aiming to create a unique, user-friendly, and entertaining party game. While we had plenty of ideas, we lacked concrete plans for developing this game. However, after the class, our objectives were broken down into smaller, more manageable pieces, which makes our development goals much clearer.
 
+  Through the introduction of stakeholders, we learned how to analyze both software users and competitors. In our project, stakeholders mainly include teachers, team members, and even fellow students in the same course, who might become potential users in the future. Identifying and defining these relationships early on allows our team to focus on the right audience and smoothly transition into the user stories and epics phase.
+
+  When working with epics, having a clear goal is essential, but understanding our users is equally crucial for building an efficient development environment. These epics can be further divided into smaller, actionable tasks based on actual requirements. For instance, in our game, one of our key epics is to create an intuitive and accessible experience for all players, regardless of whether they are first-time users or experienced ones. This epic consists of several user stories, including tailored experiences for new players, returning players, and those who prefer to skip tutorials at the beginning of the game.
+
+  Breaking down large objectives into smaller, well-defined tasks significantly streamlines the development process. Additionally, setting clear acceptance criteria ensures that our progress stays on track. If any issues arise, we can systematically analyze each step to identify where the problem occurred and make necessary adjustments.
