Designing for screen performance

Suggest edit Updated on September 12, 2020

Determine screen performance requirements for your applications. The following list describes examples of performance requirements.

  • The round-trip time from the server to the client must be 1 second or less.
  • The screen-to-screen time must be less than .5/second.

To design for these types of requirements, consider the following items.

  1. Which business service level agreements exist. For example, the customer details must be available in one second or less while an associate is talking with the customer.
  2. How long it takes backend systems to gather the data it needs to display customer details.
  3. Which fields does the associate absolutely need for the task that they need to perform.
  4. Whether any network configuration could cause latency, for example, associates logged in through the corporate VPN or in a remote location.
