Design, develop and implement basic/intermediate-level software applications.
UX Design Process:
The Double Diamond Model:
model divides the process into 2 major parts
the vision for the design and adopts a strategic approach which identifies design
problems - it encompasses activities from INTENTION to the DECISION point
- it seeks to discover and define
the execution, tactical nature, aiming to deliver a solution to the problem - from

The physical design makes things concrete and detailing the look and feel of the
product by structuring the interactions into logical sequences

people evaluate them - many techniques : sketching, storyboards, navigation maps,
wireframing, prototypes
evaluation activity: reviewing and testing the design to check if requirements are
met
⇒ these activities are interrelated with the evaluation being a central part of the design
process so that everything gets evaluated at every step of the process
The envisionment activity and its techniques
make ideas visible in order to represent design work to ourselves and to others
helps designers to see things from other’s persepective
it involves externalizing thoughts by the means of various stories, scenarios, sketches,
presentations, software prototypes..
the Sketching technique :
