The 10 most common design mistakes on the Web

May 14, 2008 · 4 Comments

  1. Not understanding the nature of the Internet.  Too often, design teams think of the Internet as a pushing media such as television or radio. Users’ behavior on the Internet is different than when they are reading books or newspapers, listening to the radio or watching television. For example, when browsing, users have goals and look for information.  If they don’t find what they are looking for, they will leave the page after 8 to 12 seconds.  Users scan web pages.  They don’t read.  If something looks like an ad, they will rapidly look someplace else.

Leading change: the practitioner’s view

January 3, 2008 · 3 Comments

A few years ago, I was in a group that got lost during a hiking trip. One member of the group said “I know the way out. We just have to turn right and walk in that direction for 10 minutes; we will see a little farmhouse and the road to civilization”. He was sure of himself. We followed his lead but after 15 minutes of walking, no sign of the little farmhouse. The group began questioning the direction. After a while, it became obvious that we were led in the wrong direction. This leader failed and the magnitude of his failure was greater because of the high degree of confidence he expressed.

You will make much more money trying to bring users to your site and ensuring good usability than trying to have beautiful flash and look.

Just back from SanFrancisco, I was trying to find an address in Montreal.
I had to slow down in order to read the street name. While slowing down, a car almost hit my back bumper! Hope it doesn’t sound familiar but I am sure it happens frequently. (more…)

Christine Whitman’s Nuclear Option

October 1, 2007 · Leave a Comment

This letter was published in Business Week

“Whitman says: “Despite its controversial reputation, nuclear is efficient and reliable.” Yet since 1950 there have been 20 nuclear accidents. One was major (on Mar. 28, 1979, at the Three Mile Island nuclear reactor) and one catastrophic (on Apr. 26, 1986, at the Chernobyl nuclear power plant). How can we say a major nuclear accident will not happen again?

July 28, 2007 · 1 Comment

You arrive at home after a long day and you rush to prepare food. You turn-on the burner but oups !, you realize that you activated the wrong burner. You feel frustrated and tell yourself “I should have paid more attention”. If it is a new stove, you might tell to yourself “I should have look at the instructions”. Some might even blame themselves for this error.
