Creating user profiles
Define high-level missions

commercial information at the same time”.

our customer to become more aware of mobileApp possibilities”.

in our commercial projects”.

faster and better (Minimize the number of escaped bugs)”.

Order the activities by asking yourself the question: “What do people do with
this system?”

For each activity, order the tasks by order or importance
