Generally speaking, the different screens are sketched prior to the testing. • Experimental Details! Adopting these aspects in the system development process, including the sustainable design will measure and accomplish users’ goals and tasks by using a specific technology. startxref Remember, you should conduct a usability review before jumping into design.
