  2. CONSIDERATION OF USABILITY IN THE DEVELOPMENT OF PRODUCT IDEAS AND CONCEPTS S10-B1: Powerpoint-Presentation»Usability«

  3. A good product is ergonomic, safe, of good quality, easy to use, aesthetic, ecological and ethical. Its design is pleasant to the user • The usability of a good product meets the needs, preferences and values of the consumer. The usability of the product increases its environment-friendliness S10-B1: Powerpoint-Presentation»Usability«

  4. When a product is usable, the user does not need or want to get rid of it quickly • When there is no frequent need to buy a new product to replace the earlier one, the product is also more economical for the consumer S10-B1: Powerpoint-Presentation»Usability«

  5. Usability can be tested in different stages of the design process, with products, services or product ideas and concepts that are in different stages • Usability is preferably tested by involving users. The role of the user can take several forms: he or she can participate in the design/product development process as a team member or just reply to a survey • Usability can also be tested without users if users cannot be consulted due to the timetable or some other reason S10-B1: Powerpoint-Presentation»Usability«

  6. Planning at an early stage is particularly important because then it is possible to have the largest influence on the product development process and this is significantly more affordable than changes made later on • See chart below . S10-B1: Powerpoint-Presentation»Usability«

  7. Planning at an early stage is decisive (source: Routio, P.) S10-B1: Powerpoint-Presentation»Usability«

  8. SELECTION OF USABILITY METHODS IN DIFFERENT STAGES OF THE PROCESS S10-B1: Powerpoint-Presentation»Usability«

  9. In order to enhance usability, it is appropriate to look for the most suitable methods for each stage of the process, each user group, each planned use, each solution to the problems, as well as the timetable and the budget • It is important to choose methods whose results enable quick and easy applications in product development S10-B1: Powerpoint-Presentation»Usability«
