Dominant Design
• “Mastering the Dynamics of Innovation”,
1994, Jim Utterback (BSIE ’63, MSIE ’65)
• Examples
– Manual typewriter (keyboard layout)
– Automobile (pedals, steering wheel, …)
– Character-mode apps in MS-DOS®
– Inside Macintosh (1985)
– Windows/IBM “Common User Access” (1987)
 CLAIM: DD has arisen for web UI, so…
…Copy Wildly
• Leverage the billions of dollars and hours
Yahoo, Amazon, Google, Facebook, etc.
and their users have invested
• Leverage the muscle memory and neural
programming people already have
Don’t have to know “why” DD is what it is
Just find a popular site and copy

KISS Principle
• Kelly Johnson, Lockheed Skunk Works
– “Keep it simple stupid” (design jet aircraft to
be repaired with simple tools in the field)
• Albert Einstein
– “Everything should be made as simple as
possible, but no simpler.”
• Leonardo da Vinci
– “Simplicity is the ultimate sophistication.”
 Metaphor, analogy, muscle memory
KISS: Fast
• Supports UI discovery (trial and error)
• Fast means
–

Fast page load (<1 second goal)
Modest use of images (branding, photos)
No text as graphics (copy, web search)
Clever use of JavaScript (AJAX)
Fast, obvious response to user action
Big vs. Small screen (mobile) UI designs
Automatic (minimize user effort)
 Facebook used to report page load time on
every page; now it can often be very sluggish
KISS: Minimal
• Minimize concepts/metaphors, words, visuals
• Form Follows Function (no graphic designers)
• Careful: left side menus for complex sites
(shopping, news are worst offenders)
• Careful: hierarchy, breadcrumb navigation
(ibm.com > about > leadership > board)
• “Elements of Style”, Strunk & White
• “The Magical Number Seven”
– Keep lists short, multiple lists in rare cases
– Alphabetize (avoid Schwab.com, etc.)
KISS: Reliable
• Be consistent:
–
–
–
–
Concepts, words, visual elements
Focus Areas (system structure/function)
Navigation elements
Defaults (easy to change)
• Never lose data (continuous save, page
navigation, remember state, errors)
• Undo (everywhere, provide history)
• Avoid modality (FB “peephole” pop-ups)
• Fast/easy bug/feedback mechanism (Google)
KISS: Simple URLs
• People email, dictate, type in URLs, so…
• Short
+ www.slivka.com/about, www.slivka.com/contact, www.youtube.com/benslivka
• Human-readable

• Stable
– Never change
• Hide implementation
– No .php, .asp, .html, etc. suffixes
KISS: On-Demand UI
• Contextual Menus: provide more commands
– Facebook, LinkedIn, Bing, Ongo, etc. have
menus/commands that appear when you hover near
content on the page
• Pop-Ups: provide more info
– “Slide out” information (Google, Facebook)
– DHTML pop-up (modal, Facebook abuses these)
– Browser window pop-up (older)
• Tradeoff: discoverability vs. too-busy page
Black on White
• Black text on white background
• Use reasonable font size
• Don’t use color alone (color blindness)
Highest contrast
Copy/paste works best
More legible on PC, smartphone, tablet
Best for people with visual impairment
(including those using screen readers)
Site Search
• People surfing the web are impatient
• Google, et. al., have conditioned us to
search
• Hunting through a hierarchy is barely OK
for browsing, frustrating if you know what
you are looking for and cannot find it
• Facebook search: name, email, page, …
 Every website should have great (and
smart) site search
Top of Page
•
•
•
•
•
Branding: logo, color/image band
Menu: short, consistent page to page
User ID: email address or username
Search: prominent search box
Date/Time: mostly for news sites
