1Identify your users and their characteristics“Know thy user, and you are not thy user”

d– Arnie Lund

Walk in their shoes and climb into their head to learn and understand their culture, context of use, aspirations, motivations and behaviors.

2Identify your usability requirements

Ask yourself:What will be measured ?How it will be measured ?How it will be measured ?What level of the measure is required ?



3Record and analyzing your users’ tasks“In the future everyone will be famous for 15

Choose the right tasks to test Tasks should beChoose the right tasks to test. Tasks should be aligned with your project requirements.



44Understanding your users’ mental models “All id d t l i t l i t ”

4“All our ideas and concepts are only internal pictures” - Ludwig Boltzmann



44This raises a number of issues for design:•What mental model might you expect the user to have?

4g y p

•What mental model should they have?•How should you convey an appropriate mental model to the user (which may have implications for training)?user (which may have implications for training)?•How should you design the interface to reflect the mental model?•How do you represent the mental model?•How do you represent the mental model?



44And Finally …The model must be discussed with representative end

4The model must be discussed with representative end users to ensure that it really does correspond to their understanding

Identify appropriate styles , standards, patterns and guidelinesBefore you start to create the user interface, you should create project specific guidelines for the task. You may have to tailor the user interface guidelines, to

When knowledge is captured in the form of a guideline, it’s known as aWhen knowledge is captured in the form of a guideline, it s known as a prescriptive theory. Prescriptive theories suggest actions to take that will lead to desired results. Guidelines aren’t rules to be enforced. They don’t eliminate creativity and innovation from the design process Instead guidelines are a vitalcreativity and innovation from the design process. Instead guidelines are a vital part of our decision strategy during the design process
