Though no one likes to miss milestones, as many of our classmates mentioned, I agree with your statement. Milestones do serve as checkpoints to ensure the project is on track. In my senior design class where we are currently working on a year long development we encounter many issues that may delay or even cause us to miss milestones and this often carries to other aspects of the project. However, they are often motivators to meet the next and continue to improve and make progress.
