November 13 Userbility TestUsability Test is critical to companies now.
1. Technology advanced far slower than years before, the model of technology driven is not sustainable right now.
2. Companies should be more product driven and customer driven
3. Consumers don’t know what they want, they can just decide when you offer
A very good example is the iPhone. It’s quite inspiring phone and as for the revolutionary user experience.
1. Compelling UI
2. Elegant mechanical design
3. Simply for consumer.
In one word, I love the phone.
Some tech fans may complain that Apple restrict so many operations on the phone, you can not customize everything. But I believe 90% of the consumers not care about it. What they care about is the usability. But the PDA phones made the operations so complex that most of people don’t know how to use them.
Many improvements are not relevant to technology, such as the position sensors and the ambient light sensors have been around for years. It’s really nothing special. But Apple made it perfect in usage. They cover a lot of details which made you think they really put thoughts on the product. E.g. when you pull out the earphone, the iPod will suspend and when you plug in again, the iPod will resume automatically. It’s small but will save me a lot of time in manually start/stop it.
Bunch of Tools and Theories covered the Usability Test.
You can use those tools in different product stages:
1. Ideation: vision, ethnographic field study, focus groups, diary studies, survey, data mining
2. Pre launch: Card Sorting, paper prototype, usability studies, participatory design, desirability study and field study
3. Post Launch: usability benchmarking, online assessment, customer emails, surveys and A/B testing
Among them, A/B Test is quite popular in internet business. A formal description can be found at wikipedia:
A/B testing (also known as split testing) is a method of advertising testing by which a baseline control sample is compared to a variety of single-variable test samples in order to improve response rates. A classic direct mail tactic, this method has been recently adopted within the interactive space to test tactics such as banner ads, emails and landing pages.
It has been widely used in Advertisement industry, which turned out to be quite useful in new tech industry.
