- 1. PERFORMANCE VS. PREFERENCE Mary Rose O’Donnell
- 3. PERFORMANCE Dvorak rules Based in science/research However…
- 4. PREFERENCE QWERTY rules people still use it No one is in a rush to change their preferences because of performance People like what they like
- 6. “The best way to correctly balance performance and preference in design is to accurately determine the importance of performance versus preference” (Lidwell).
- 7. DETERMINING DESIGN REQUIREMENTS Observe people interacting with your design in “real life” Preference information in context Current experiences
- 8. HOW DOES THIS RELATE TO US? Designers tend to make most design decisions based on their personal preferences (Bailey). Remember the user when creating design for GitHub site, Photoshop projects, etc.
- 9. EXAMPLE: APPLE VS. ANDROID
- 10. OVERALL: Performance matters Preference matters Need a balance

Editor's Notes
- My pecha kucha is on performance vs. preference in terms of design requirements Quick definitions This adds a different layer to the saying the “customer is always right”
- Example the universal principles of design book gives: Dvorak keyboard vs. QWERTY keyboard QWERTY keyboard is our standard keyboard Dvorak was developed in 1936 has most consonants on the right side of the home row, vowels on the left side of the home row Has a back and forth hand motions Said users can type 30% faster on this keyboard
- In terms of performance, the Dvorak keyboard is better The product/”thing” that is “scientifically” proven to produce better results Doesn’t always align with what people prefer
- Though the Dvorak keyboard is proven to perform better than QWERTY, QWERY is the standard because it has been used for so long and is ingrained in society We are all pretty familiar with this concept People prefer different things for many reasons – colors, design, they know how to use it, the brand, etc.
- When coming up with design requirements, its important that factors like visuals, long-standing design standards, and ease of use/user well-being are balanced Like the keyboard, if people don’t buy it or prefer, who cares if it performs better than alternatives If a product that people like isn’t helping people perform at a base level, who cares if people like it? People need to be able to like what they are using, but also benefit from it and perform to an acceptable standard while using it
- Can be tricky Surveys, interviews, etc can figure out what people like and r into Doesn’t mean they’ll actually buy or use the product outside of that survey, interview, etc. For most people, the line between discriminating features they like vs. features that are actually enhancing their performance is pretty blurred
- Instead of surveys and methods that were previously mentioned, the universal principles of design book recommends observing people while using your design The best way to get performance vs. preference is this way because the user is actively performing tasks and evaluating what they are feeling in the moment, as opposed to afterwards Doesn’t matter about the past or future experience, only their present experience
