Hinweis der Redaktion
- A common issue is adding all the features we think the users need This is how products become complicated We need to focus on what matters to users
- This takes me to the definition of usability. It is not about esthetics, it is… We need to help the different types of users achieve their goals, and we need to understand how they perform their tasks We need to measure the design Efficiency Effectiveness Satisfaction
- To ISO 9241: The World's most influential usability standard ISO 13407: Human-centred design processes for interactive systems ISO TR 18529: Human-centred lifecycle process descriptions Guidelines: for windows, for the web Principles: error prevention, user control, minimizing workload Research: testing with users Science: Chunking: making more efficient use of short-term memory by recoding information in chunks. Similarity: When two elements have a similar size and shape, the brain will link them together Fitts law: Calculates time it takes to point at something, based on the size and distance of the target object.
- To conclude, here are few points to remember: Usability is about a design adapted to users. We do not want to train users and have them rely on support. They should find the design intuitive and learn it by themselves. As you saw from the benefits, Usability has a huge impact on cost and performance. The ROI of these projects is high and can easily be calculated In the booklet you will find the slides and all the details we did not read. You will also find questions based on the usability maturity model. These questions will give you an idea about few steps you can take. We are all here to answer your questions And Feel free to come see us after the event. Thank you
