Task analysis which includes identifying Users, learning about users’ tasks, coming up with a representative task description and evaluation. Application of tasks which includes the production of a scenario that spells out what a user would have to do and what he or she would see step-by-step in performing a task using a given system. Creating an initial design which is better achieved due to several reasons by Borrowing i.e. building your design on other people's good work rather than coming up with your own design ideas. 6.0 TUTOR MARKED ASSIGNMENT a.
