Website usability writing

Beginning in 1996, Nielsen published a fortnightly column about website usability called Alertbox<ref>Template:Cite web</ref><ref>Template:Cite web</ref> on his now-archived personal website useit.com. Alertbox was syndicated to, and eventually replaced by, the weblog and email newsletter on the Nielsen Norman Group website during the 2000s.

Nielsen has published several books on the subject of web design.<ref name=":0" /><ref name=":3" /> He was a Series Editor for Morgan Kaufmann Publishers' book series focused on interactive technologies.<ref>Template:Cite book</ref>

Nielsen founded UX Tigers in 2023 where he currently publishes articles on the topics of usability, with a heavy focus on the intersection of digital usability and artificial intelligence,<ref>Template:Cite web</ref><ref>Template:Cite web</ref> and publishes video content about usability.

Nielsen Norman Group (NNG)

After his regular articles on his website about usability research attracted media attention, he co-founded usability consulting company Nielsen Norman Group (NN/g) of Fremont, California in 1998 with fellow usability expert Donald Norman.<ref name=":0" /><ref name=":02">Template:Cite web</ref><ref>Template:Cite web</ref> The company's vision is to help designers and other companies move toward more human-centered products and internet interactions, as experts and pioneers in the field of usability.<ref name=":02" />

Nielsen founded the usability engineering movement for efficient and affordable improvements of user interfaces and he has invented several usability methods, including heuristic evaluation. He holds more than a thousand United States patents,<ref>Template:Cite web</ref><ref>Template:Cite web</ref> mainly on ways of improving usability for technology.

In the early 1990s, Nielsen popularized the principle that five test users per usability test session is enough, allowing numerous tests at various stages of the development process.<ref name="useit" /> His argument is that "elaborate usability tests are a waste of resources." Once it is found that a few people are totally confused by a home page, little is gained by watching more people suffer through the same flawed design.<ref name="useit">Template:Cite web;

Jakob's law

Template:Anchor Users will anticipate what an experience will be like, based on their mental models of prior experiences on websites.<ref>Template:Cite web</ref><ref name=":5">Template:Cite web</ref> When making changes to a design of a website, try to minimize changes in order to maintain an ease of use.<ref name=":5" />

Nielsen's usability heuristics

Template:See also Template:Anchor Nielsen's list of ten heuristics is probably the most-used usability framework for user interface design. An early version of the heuristics appeared in two papers by Nielsen and Rolf Molich published in 1989–1990.<ref>Template:Cite journal</ref><ref name=mol>Template:Cite journal</ref> Nielsen published an updated set in 1994,<ref>Template:Cite conference</ref> and the final set still in use today was published in 2005:<ref>Template:Citation</ref>

  1. Visibility of system status
  2. Match between system and the real world
  3. User control and freedom
  4. Consistency and standards
  5. Error prevention
  6. Recognition rather than recall
  7. Flexibility and efficiency of use
  8. Aesthetic and minimalist design
  9. Help users recognize, diagnose, and recover from errors
  10. Help and documentation

In his book Usability Engineering (1993), Nielsen also defined the five quality components of his "Usability Goals":<ref>Template:Cite book</ref>

  1. Learnability
  2. Efficiency
  3. Memorability
  4. Errors (as in low error rate)
  5. Satisfaction

Windows 8 usability

Nielsen has been quoted in the computing and the mainstream press for his criticism of Microsoft's Windows 8 (2012) user interface.<ref>Template:Cite web</ref><ref>Template:Cite web</ref><ref>Template:Cite news</ref> Tom Hobbs, creative director of the design firm Teague, criticized what he perceived to be some of Nielsen's points on the matter, and Nielsen responded with some clarifications.<ref>Template:Cite web</ref> The subsequent short and troubled history of Windows 8, released on 26 October 2012, seems to have confirmed Nielsen's criticism: the sales of Windows-based systems plummeted after the introduction of Windows 8;<ref>Sebastian Anthony, April 11, 2013. Windows 8 causes most precipitous PC decline in history. https://www.extremetech.com/computing/153111-windows-8-causes-most-precipitous-pc-decline-in-history</ref> Microsoft released a new version, Windows 8.1, on 18 October 2013, to fix the numerous problems identified in Windows 8, and later released Windows 10, a complete overhaul, in July 2015.

Criticisms

As Nielsen's newsletter and website grew, and with his use of "acronomic platitudes"<ref name=flame>Template:Cite web</ref> to describe his concepts, some critics like Philip Greenspun argued that Nielsen's work was more about marketing himself than any particular research.<ref name=":3" />

Nielsen's usability heuristics

In 1990, when the Nielsen heuristic evaluation guidelines were created,<ref name=mol/> user interface was less complicated than it is in present-day.<ref>Template:Cite web</ref><ref name=":1">Template:Cite web</ref> There has never been any research-based validation of Nielsen's heuristics.<ref name=":1" /> Researchers at the University of Calgary published an article in 2008, questioning if the Nielsen heuristics were an oversimplification.<ref>Template:Cite web</ref>

Nielsen has been criticized by some visual designers and graphic designers for failing to balance the importance of other user experience considerations such as typography, readability, visual cues for hierarchy and importance, and eye appeal.<ref>Usability News Template:Cite web, July 31, 2002</ref><ref>Curt Cloninger "Usability experts are from Mars, graphic designers are from Venus" July 28, 2000</ref>

Responsive design

Nielsen's 2012 guidelines, "Repurposing vs Optimized Design" that web sites made for mobile devices be designed separately from their desktop-oriented counterparts has come under fire from Webmonkey's Scott Gilbertson,<ref>Template:Cite web</ref> as well as Josh Clark writing in .net magazine,<ref>Template:Cite web</ref> and Opera's Bruce Lawson, writing in Smashing Magazine,<ref>Template:Cite web</ref> and other technologists and web designers who advocate responsive web design.<ref>Template:Cite web</ref><ref name=":4">Template:Cite web</ref> In an interview with .net magazine, Nielsen explained that he wrote his guidelines from a usability perspective, not from the viewpoint of implementation.<ref>Template:Cite web</ref>

Nielsen has been accused of taking a "puritanical" approach to usability, and not being able to keep up his usability evaluations in step of technological changes.<ref name=":3" />
