Donald A. Norman Quote

The designs of our products and services must also follow this philosophy. So, to the designers who are reading this, let me give some advice: •​Do not blame people when they fail to use your products properly. •​Take people’s difficulties as signifiers of where the product can be improved. •​Eliminate all error messages from electronic or computer systems. Instead, provide help and guidance. •​Make it possible to correct problems directly from help and guidance messages. Allow people to continue with their task: Don’t impede progress—help make it smooth and continuous. Never make people start over. •​Assume that what people have done is partially correct, so if it is inappropriate, provide the guidance that allows them to correct the problem and be on their way. •​Think positively, for yourself and for the people you interact with.

About Donald A. Norman

Donald Arthur Norman (born December 25, 1935) is an American researcher, professor, and author. Norman is the director of The Design Lab at University of California, San Diego. He is best known for his books on design, especially The Design of Everyday Things. He is widely regarded for his expertise in the fields of design, usability engineering, and cognitive science, and has shaped the development of the field of cognitive systems engineering. He is a co-founder of the Nielsen Norman Group, along with Jakob Nielsen. He is also an IDEO fellow and a member of the Board of Trustees of IIT Institute of Design in Chicago. He also holds the title of Professor Emeritus of Cognitive Science at the University of California, San Diego. Norman is an active Distinguished Visiting Professor at the Korea Advanced Institute of Science and Technology (KAIST), where he spends two months a year teaching.
Much of Norman's work involves the advocacy of user-centered design. His books all have the underlying purpose of furthering the field of design, from doors to computers. Norman has taken a controversial stance in saying that the design research community has had little impact in the innovation of products, and that while academics can help in refining existing products, it is technologists that accomplish the breakthroughs. To this end, Norman named his website with the initialism JND (just-noticeable difference) to signify his endeavors to make a difference.
