Offer Informative Feedback

Another difference between Web applications and installable desktop software is the inherent latency limitations of the Web, even within intranets. Your Web application will not be able to respond to customer actions immediately. Your customers will become impatient and will often commit errors, such as executing the same command multiple times or inadvertently interrupting a command. Although you might want to give your customers more room for their work in your Web application, eliminating the standard browser buttons and controls could cause a problem. This design will eliminate the browser feedback showing that a command is in progress, such as Internet Explorer's spinning globe. However, many designers have found that this feedback is insufficient for Web applications anyway. Following our design principle from Chapter 4—Involving Customers with Iterative Design, offer informative feedback: Include in your PROCESS FUNNEL (H1) a progress bar for any communication or processing that will take longer than ten seconds. Also design your pages so that they will be fast to download, as described in Pattern Group L—Speeding Up Your Site.
