Improving Interface Design Web Visions Portland, OR | May 3rd, 2007 1 Jakob Nielsen A field study identified twenty-two ways that automated hospital systems can result in the wrong medication being dispensed to patients. Most of these flaws are classic usability problems that have been understood for decades. ? ? http://www.useit.com/alertbox/20050411.html 2 Roger Martin A reliable process--which tends to attract folks in finance, engineering, and operations--produces a predictable result time and again. This is business as algorithm: quantifiable, measurable, and provable. ? ? http://www.fastcompany.com/magazine/109/open_design-tough-love.html 3 Roger Martin A valid process, on the other hand, flows from designers? deep understanding of both user and context, and leads them to ideas they believe in but can?t prove. They work in a world of variables: the unpredictable, the visual, the experimental. ? ? http://www.fastcompany.com/magazine/109/open_design-tough-love.html 4 Roger Martin The challenge is to manage the chronic push and pull between a value system premised on what?s valid and one based on what?s reliable. ? ? http://www.fastcompany.com/magazine/109/open_design-tough-love.html 5 User Experience Usability Design (Visual & UI) Project Mgmt.

It?s about communication and problem solving. 8 1 8 Steve Jobs Design is not just what it looks like and feels like. Design is how it works. ? ? 9 10 http://nymag.com/nymetro/health/features/11700/ 11 12 http://nymag.com/nymetro/health/features/11700/ 13 Jeff Veen I?ve been amazed at how often those outside the discipline of design assume that what designers do is decoration. Good design is problem solving. ? ? 14 15 Bob Baxley Like all forms of design, visual design is about problem solving, not about personal preference or unsupported opinion. ? ? 16 http://worrydream.com/MagicInk/#p121 17 http://worrydream.com/MagicInk/#p126 18 Components of Usability (http://www.useit.com/alertbox/20030825.html)) Learnability. How easy is it to accomplish basic tasks on the first encounter of an interface? Efficiency. Once users are familiar with the interface, how quickly can they perform tasks? Memorability. When users return after a period of not using the interface, how easily can they reestablish proficiency? Errors. How many errors do users make, how severe are the errors, and how easily can they recover? Satisfaction. How pleasant is it to use the interface? 19 Smallest Effective Difference Edward Tufte Make all visual distinctions as subtle as possible, but still clear and effective. 20 http://www.37signals.com/svn/posts/137-design-decisions-basecamp-help 21 Charles Eames The details are not the details. They make the design. ? ? 22 http://gmail.com 23 http://threadless.com 24 http://writeboard.com 25 http://psychology.wichita.edu/surl/usbilitynews/62/whitespace.htm 26 http://nytimes.com 27 Web Visions Portland, OR | May 3rd, 2007 External Inspiration History, art, other mediums, other professions.

These are all analytical fields. The discipline prides itself on its scientific basis and experimental rigor. The hidden danger is to neglect areas that are not easily addressed in the framework of science and engineering. http://www.jnd.org/dn.mss/emotion_design.html ? ? 36 Web Visions Portland, OR | May 3rd, 2007 Cultivate the Culture Lipstick on a pig doesn?t cut it. 37 2 37 Conway?s Law It is a consequence of the fact that two software modules A and B cannot interface correctly with each other unless the design and implementer of A communicates with the designer and implementer of B. Thus the interface structure of a software system necessarily will show a congruence with the social structure of the organization that produced it. 38 39 Benjamin Franklin The definition of insanity is doing the same thing over and over again and expecting different results. ? ? 40 http://positivesharing.com/happyhouris9to5/bookhtml/happyhouris9to55.html 41 Khoi Vinh Design groups really need a strong, diplomatic leader who can help engender a climate for good design. ? ? 42 Web Visions Portland, OR | May 3rd, 2007 Think Critically If the question is wrong, the answer is irrelevant. 43 3 43 Bertrand Russell The greatest challenge to any thinker is stating the problem in a way that will allow a solution. ? ? 44 http://www.infotoday.com/online/nov05/morville.shtml + 45 Courtesy of Cameron Moll 46 Courtesy of Cameron Moll 47 Courtesy of Cameron Moll 47 Jack Welch Too Often we measure everything and understand nothing. ? ? 48 49 Benjamin Disraeli There are three kinds of lies: lies, damned lies, and statistics. Popularized in the U.S. by Mark Twain ? ? 50 Web Visions Portland, OR | May 3rd, 2007 Ignore Users We have to look beyond what people say and understand their real needs. 51 4 51 Jakob Nielsen To design an easy-to-use interface, pay attention to what users do, not what they say. Self-reported claims are unreliable, as are user speculations about future behavior. ? ? http://www.useit.com/alertbox/20010805.html 52 53 54 Sidney Deane Look man. You can listen to Jimi, but you can?t hear him. There?s a difference man. Just because you?re listening to him doesn?t mean you?re hearing him. ? ? White Men Can?t Jump, 1992 55 http://www.cree.com/press/press_detail.asp?i=1175179209372 56 Steve Jobs It?s really hard to design products by focus groups. A lot of times, people don?t know what they want until you show it to them. ? ? 57 Web Visions Portland, OR | May 3rd, 2007 Document & Code Better Current state of traditional and expected documentation is atrocious. 58 5 58 59 http://dilbert.com/comics/dilbert/archive/images/dilbert2007458210412.gif 60 1. User enters the building 1.1 User opens door. (See Misc-01) 1.2 User walks through door. 1.3 User closes door. 2. User leaves the building. 2.1 User opens door. 2.2 User walks through door. 2.3 User closes door. Misc-01 Outside doors should open inwards and the knob should be placed towards the outer edge of the door about waist high. The doors should be 7?2? tall and 3? wide. 61 62 63 Getting Real No matter how much you plan you?re likely to get half wrong anyway. So don?t do the ?paralysis through analysis? thing. That only slows progress and saps morale. Getting Real http://gettingreal.37signals.com/ch06_Done.php ? ? 64 65 Getting Real The same way you should regularly put aside some of your income for taxes, regularly put aside some time to pay off your code and design debt. If you don?t, you?ll just be paying interest (fixing hacks) instead of paying down the principal (and moving forward). ? ? http://gettingreal.37signals.com/ch10_Manage_Debt.php 66 67 68 <script type="text/javascript" language="javascript"> document.write("<a href=\"javascript:salesWindow();\" onclick= \"resetTimer()\" onFocus='javascript:window.status=\"Get a higher return plus penalty-free withdrawals.

While specialization has its advantages, it also creates a situation where staffers see just their own little world instead of the entire context... http://gettingreal.37signals.com/ch07_Unity.php ? ? 74 A Bridge River B 75 Bridge River A B C 76 77 http://www.joelonsoftware.com/items/2006/11/21.html 78 Peter Morville The design of good houses requires an understanding of both the construction materials and the behavior of real humans. ? ? 79
