Validation
Validations are iterative tests of concepts and prototypes across the development process of an application. They help identify weak points and optimize on development potentials. The focus is on technical and functional validity as well as the mental models of users and their needs for the use of the product. Following Validation are Usability Tests in which users actively try out the system themselves.
Nice to know:
