Task Analysis and Product Design

by Olga Werby • January 15, 2013

Imagine your were given an assignment to develop a product that could help people eat healthy. How would you go about creating such a thing? What would you need to learn/understand? What is the right medium or technology vehicle for such a product? How would you even start? Below is a very brief outline of how to get started and the key tools necessary for the job. Project Goals The first order of business is figuring out the business needs and goals: What is the product really supposed to do? You have to ask this even if you are the one who is the client on this project. But, most probably, you are working for someone else — the client — and you have to start by understanding what your client really wants to do. You can do that in several ways: Analyzing the Request for Proposals: On many such projects, there will be an initial document, something like an RFP, that outlines the business goals and desires of the client. While some RFPs are very detailed and fully fleshed out, most are not. There are many reasons for this. Some clients are worried someone will “steal” their ideas and…

Kurisumasu ni wa kentakkii!

by Olga Werby • December 17, 2012

Who would have thought that our KFC fried chicken would be an object of desire in Japan? But perhaps all it takes is some very good PR (and some luck), and a product designed to please a very specific audience finds a new user group… Kentucky Fried Chicken for Christmas Dinner Japanese tradition started in 1974. While Japan is not a Christian nation — most Japanese (84% to 96%) identify themselves as Shinto or Buddhists — people do celebrate Christmas. There are Christmas office parties, people put up trees and give gifts, and families and friends eat Christmas dinners together. But unlike here in U.S., Christmas turkey dinners are not common — it is almost impossible to get a turkey at a local supermarket. To celebrate the Christmas spirit with an authentic American flavor, Japanese turn to KFC! The Kurisumasu ni wa kentakkii — or Kentucky for Christmas — is so popular, that people have to order their Christmas fried chicken buckets a month in advance! This is the power of advertising.

Babies, Siri, and Voice-activated Controls

The new generation will grow up with Siri: What will this mean to their expectations of how devices should/could work? What are the implications to product design and interaction design?

Who Controls Social Networks?

by jpcochran • October 30, 2012

Article: Bohannon, J. (2012). “Who Controls Social Networks?” sciencemag.org. Visited on Oct 9, 2012:http://news.sciencemag.org/sciencenow/2012/06/who-controls-social-networks.html This article is about how ideas spread in social groups through peer influence. A theory long debated is that a small number of people who are influencers spread ideas through their peer groups. Critics of the theory argue that is it not how much influence these people have but how susceptible to the new idea people are. The study of peer influence has proven difficult to conduct, but the rise of social networks such as Facebook provide a means for researchers to study a large number of people. One study in the article found that on Facebook there was a clear divide between influencers and those that were susceptible to new ideas. Conceptually, it’s important for any product developer to understand who their product’s influencers are if they wish their product to spread through peer influence. The article suggests that the personality traits of people affect influence. Examples: Women influence men more than women. People over 30 were more influential than those under 30. The article states that the most important finding is that Influencers and those who are susceptible are not traits found within the…

RE: Perfectionism May Not Be Optimum

by Micah Johnson • October 28, 2012

Tugend, A., (2011). “It’s Just Fine to Make Mistakes.” NYTimes.com. Visited on October 8, 2012: http://www.nytimes.com/2011/03/12/your-money/12shortcuts.html Experiment: A study was conducted comparing the productive abilities of participants testing high and low in “perfectionism”. The task was to rephrase a passage without interpretation for a panel of judges who were unaware of the status of the participants. The Outcome: Those rating high in perfectionism were judged to have passages “significantly poorer in quality”. This surprising finding can be attributed to a shortened process of learning in perfectionists, due to fear of failure and the loss of respect should a mistake be found. This isolation from feedback inhibits development. Additionally, the stress of perfectionism can be psychologically detrimental, further inhibiting learning especially in the face of failure. Interaction Design: For products with a high learning curve, built-in feedback could be considered when the product is not used as designed, and alternately when ideal conditions of usage are met. This would perhaps encourage experimentation and calibrate use. Interface Design: Friendly tone or customizable interface might also help to attract continued use. This could give perfectionists and non-perfectionists a positive working arena.

The Language Comprehension Continuum

by Olga Werby • October 12, 2012

Below is an example of communication error — Penn and Teller use strong emotional language and delivery to hide the true meaning of the message. In context — a pretty young woman anxiously and passionately asking individuals at a faire to protect the environment — signing the petition makes sense. People sign many petitions. And the more people sign (or the more signatures they see on the petition), the more likely others sign as well. A woman, seemingly in distress over an environmental problem, inspires an emotional reaction — people want to help. We have a built-in social value system that encourages this kind of behavior. And finally there’s a strong p-prim that all chemicals are bad — so just hearing a chemical compound in a petition gets a response from the crowd. The result? On the language comprehension continuum, these faire goers didn’t do so well…
