You want your application to respond immediately as your end users interact with customers. As you design your user interface, complete the following steps:

1. Review transactional service level agreements.

   For example: The customer details must be available in one second or less while a representative is on the phone with the customer.

2. Review service performance, such as how long it takes back end systems to gather the data needed to display customer details.

3. Review data requirements to determine which fields contain the information that the representatives absolutely need for the task that they need to perform.

4. Determine if any network configuration could cause latency.

   For example: Representatives who are logged in through a corporate VPN or in a remote location might cause an issue.
