- knowledge
- attention
- memory and working memory
- judgement and evaluation
- reasoning and computation, problem solving and decision making

DESIGN
Design is a plan scheme in mind and intended for subsequent execution. it must be a practical and creative idea. design that was created must develop a product that help its users achieve their goals.
How Can A Design Achieve A Goal?
®Must begin
with gaining some understanding of what is required of it. For example,
¯where do these requirements come from?
¯whom do we ask about the requirements?
® Involving
users
¯But who are
the users?
¯Do/will they
know what they want or need?
4 Basic Activities Of Design
1. Identifying Needs and Establishing Requirements
* Who are the users?
* What can the product provide to its users?

2. Developing Alternative Designs
*Conceptual design
*Physical design
3.Building or Development
*Paper-based prototype
*Sketch
*Blueprint
4.Evaluating
*Determine the usability and acceptability of the product or design
*determine number of errors users make using it
Life-cycle Design Model.
Simple Life-cycle Design Model
*Show how activities are related each other.
*Life-cycle models are:
-management tools
-simplified versions of reality
*Many life-cycle models exist, for example:
-Software engineering:
- waterfall
