Abstract
Software Quality still a vague and multifaceted concept, which means different things to different people, metrics for object oriented design focuses on measurements that are applied to the class and design characteristics. These measurements allow designers to access the software early in process, making changes that will reduce complexity and improve the continuing capability of the design. This paper focused on a set of object oriented metrics that can be used to measure the quality of an object oriented design. We study carefully Metrics for object oriented design and focus on MOOD model.
