5. Application definition: User-centred Design“ User-centred design is a process inwhich the needs, wants, and limitationsof end users of a product are givenextensive attention at each stage of thedesign process ” Wikipedia
6. User-centred Design: the Goal The user is the kingThe functional and user-experience requirements are validated and tested with the users

12. User-centred Design: Methods and TechniquesANALYSIS & REQUIREMENTSSTICKY NOTESComparing notes is a useful tool to aid decision making. Ideas are written down onindividual sticky notes, weighed against one another and organised according topriority or other criteria. This technique can also be used with users to get them toput their considerations in order of importance.USER REQUIREMENTSIt is vital to use all available resources to gather information about the users’requirements. Successful projects use different sources of information: focus groups,contextual or individual interviews, observation, surveys …PERSONAS & SCENARIOSA persona is an archetype comprised of habits and characteristics of the targetaudience. Scenarios are little stories describing how typical user tasks are carriedout. They help to anticipate and identify the decisions a user will have to make ateach step in their experience and through each system state they will encounter.
13. User-centred Design: Methods and TechniquesINFORMATION, STRUCTURE & VISUAL DESIGNRAPID VISUALISATIONVisualising ideas and concepts rapidly using pen and paper is helpful tocommunicate them to the team and to test ideas quickly without investing time andresources into polished design. Rough and unpolished looking sketches, wireframesand storyboards encourage constructive feedback and stimulate discussion.PROTOTYPINGPrototypes are models that can be used to evaluate responses to form (looks-likeprototype) or aspects of build and functionality (works-like prototype) of a product.They typically evolve from concept sketches or wireframes to low and high-fidelitymodels as they progress through the definition cycle.USER TESTINGEvaluating a product by testing it with representative users helps to identify usabilityproblems by collecting quantitative data on the users’ performance (e.g. error rate)and establishing their satisfaction with the product.

17. Application Prototyping: Questions Could you imagine VOLKSWAGEN producing cars without designing prototypes and testing these prototypes? Could you imagine IKEA producing furnitures without designing prototypes or proof of concepts?
18. The Value of Prototyping1. It’s Generative2. Show and Experience3. Reduces Misinterpretations4. Saves Time and Money5. Reduces Waste

24. Barriers for Prototyping We don’t have time for prototypes We don’t have budget for prototypes We need to change our design process
25. The Biggest MistakeI want to reuse the code of my prototype Why not? It’s time to define the right solution !!! It’s time to fast iterations and changes !!! Are you sure you want the code before a technical design (UML, Database design,…)?
26. Benefits of a Prototyping-oriented processPrototype does have a cost. It’s not free but … Proposal are: 50 % accurate Request for clarification from developers: 80 % Amount of rework and bug fixes: 25 %
