iOS apps estimated at 367,334 in 2011-- Plugged In, May 5, 2011
“App markets . . . offered by Apple, Google, Nokia, and RIM sold $2.1 billion worth of apps in 2010. ” -- Talk Android, May 6, 2011
77 percent of the world population are mobile subscribers, with growth led by China and India--MobiThinking, March 2011
Why focus on apps?

“$800M spent on mobile advertising, rising to a healthy $5 billion over the next five years. . . . [I]nventory [is currently] available from 50+ networks and 9,000 publishers.” from http://www.mobilemarketingwatch.com/report-mobile-apps-are-hot-but-mobile-search-drives-the-most-revenue-10894/
“[A]pps attracted just 2% of mobile ad spend in the US, while search is the biggest draw overall with 46%, followed by display with 29%”--MobileMarketingWatch
Why focus on apps?

Like web design in last two decades, app design constitutes the next big design problem to solve
Why focus on apps?

what are best practices for app design?
what makes an app design good?
how is app design different than designing for a desktop?

User-Centered Iterative Design

Rapid Prototyping
“learning by creating”
“Iterating is designing and, more specifically, understanding what one is designing through actually creating it. . . . Iterative design also means that until you have actually built what you are designing, you are not going to be able to fully understand it.
--Anders Ramsay, http://www.andersramsay.com/2009/03/01/three-reasons-to-start-designing-iteratively

Incremental vs. Iterative Design

According to Anthony Hutton: “Design is an iterative process. Sometimes (most times) you will need to go back to the previous step. On some occasions the project will be nearly complete when you need to start again. The process looks like a waterfall that can flow upstream.”
From “Mobile Creativity,” http://www.foylearts.net/ahutton/mobile/

Iterative design sees design as a cyclical process involving three activities

evaluating
designing
prototyping

Top three pitfalls of a linear approach• Too much time spent on designing strategies that are likely to change
• The client doesn’t see the design until very late in the process (this usually results in endless revisions, change requests and roll-out delays)
• Actual implementation takes too long–thereby delaying user feedback and evaluation
From “Getting the Lead Out” from http://fsimmons.ca/blog/

A group of techniques used to quickly produce a model of a part or whole of a project using computer-based technologies and data. “What is commonly considered to be the first RP technique, Stereolithography, was developed by 3D Systems of Valencia, CA, USA. The company was founded in 1986, and since then, a number of different RP techniques have become available.”

What is Rapid Prototyping?
15
• Increase effective communication• Decrease development time• Decrease costly mistakes• Minimize sustaining [technological]
changes• Extend product lifetime by adding
necessary features and eliminating redundant features early in the design
• Increase number of variants of products
• Increase product complexity• Decrease product lifetime before
obsolescence• Decrease delivery time
