Good design outlines a design process that puts human needs, capabilities, and behaviour at first place. As Norman writes in his book:
“Good design requires good communication, especially from machine to person, indicating what actions are possible, what is happening, and what is about to happen. Communication is especially important when things go wrong. It is relatively easy to design things that work smoothly and harmoniously as long as things go right. But as soon as there is a problem or misunderstanding, the problems arise. This is where good design is essential.”

Real life example from one of our authors:
“That book made me realize how important is the design not only for websites but for every object around us. I have started to notice how usable and functional are the things I use every day, the websites I browse, the mobile apps that I have on my phone and I realized that a lot of them were very badly designed. Some of them have made me very angry and I left them, except I did not have another choice. The following image is an example of very annoying design.”
“The goal of the task was to purchase tickets for a forthcoming game and the opposite team have sold out their tickets, so I did not have another choice. To buy tickets, I had to fill in several different forms, which was quite long but it was not a problem as long as I knew I am closer to complete my goal. At the end of the task, I had to submit my card and pay for the tickets, but the “Cancel” button is so prominent and identical as all previous buttons for agreement so I clicked it by accident and that returned me in the beginning. At the second try, I was much more careful and I slowly clicked the “Submit” button but something with the system went wrong and I was in the beginning again. At this point, I was very annoyed with their website and I definitely will not recommend it or go back to it.”
We face many non-functional and not user-friendly designs every day and this is only a single example that clearly shows how important is to make sure things are designed in a way that enables people to use them successfully.
