Kuali Student Accounts Performance Expectations and Goals

Various sources, 13 April 2013

Nielsen on Performance

1.

0.1 second (100 milliseconds) is about the limit for having the user feel that the system is reacting instantaneously.

2.

1.0 second is about the limit for the user's flow of thought to stay uninterrupted, even though the user will notice the delay.

3.

10 seconds is about the limit for keeping the user's attention focused on the dialogue. For longer delays,users will want to perform other tasks while waiting.

Jakob Nielsen (1993: September 23) Usability Engineering. Boston: Academic Press as excerpted in his Alert Box blog, January 1, 1993.

Nielsen on Performance: Principles

Eradicate the term "web-based application“ because it distracts from the real issue, which is one of application UI design. The fundamental usability recommendations [are broadly applied] … since we are discussing user experience, not coding.

In cases where the computer cannot provide fairly immediate response, continuous feedback should be provided to the user in form of a percent-done indicator [Myers 1985 ]. As a rule of thumb, percent-done progress indicators should [only] be used for operations taking more than about 10 seconds.

Jakob Nielsen from his Alert Box blog, January 1, 1993.

Nielsen: College Students and Adults

Jakob Nielsen (2013, February 4) Teenage Usability: Designing Teen-Targeted Websites. Alertbox blog.

Neilson on Teens

Teens perform worse than adults (71% compared to 83%) for three reasons:• Insufficient reading skills• Less sophisticated research strategies• Dramatically lower levels of patience

Response Time ExpectationClick/Enter to full screen rendered

Harry Shum as quoted in the New York Times, “The Blink of an Eye? Oh Please,” 29 February 2012250 milliseconds is a Microsoft goal.

Google’s Response Time Goal

“We want you to be able to flick from one page to another as quickly as you can flick a page on a book. So we’re really aiming very, very high here… at something like 100 milliseconds.”

~Urs Hölzle, Senior VP Operations, Google

Quoted by Joshua Bixby, Web Performance Today, 23 September 2010 based on video from Urs’ presentation at Velocity in June.

Performance Goals

• Google – 100 milliseconds• Microsoft – 250 milliseconds• Neilsen-Tilton (in context of KSA)

100 milliseconds for added productivity

200 milliseconds for screens except1 Second for those with complex algorithms10 Second maximum for user attention in every case
