Group Exercise!• Form groups of 3-5 persons!
– Within each group, try to fulfill the following two tasks:
• Task 1: – Name as many concrete experiences in private or professional life,
where you have already used an approach similar to the double-diamond idea – or where you think in afterthought it would have been applicable
– Result: List of situations in keywords, as many as possible
• Task 2: – Which tools and techniques do you know to support the steps of
• envisioning • understanding • designing • evaluating?
– Result: List of keywords4SlideBased on Material by A. Butz & A. Krüger

Questions• What do you think was the meaning of the colors of the
sticky notes? • How much time should be spent on such conceptual design
activities? • How can we assess the quality of the result of
conceptual design?

Implementation• During the process only prototypes have been developed • Source code of prototypes usually is not re-usable
– this is intentional! See chapter on prototyping…
• Final implementation brings on new challenges – Scalability – Platform diversity – Error tolerance – Commercialization – …others? discussion…

• Fidelity = Similarity of details in prototype implementation to final system (e.g. drawing sketch vs. photorealistic rendering)
