Community Board of Realtors :

One of the key use cases for the Multiple Listing Service system is Create new listing, where the realtor enters all the important information about a new listing he or she has obtained.

Realtors want to be able to create a new listing as soon as possible so other realtors and potential buyers will find the listing online. Some like to enter the information while talking with the owner or while inspecting the property. Realtors are rarely in their offices these days, so being able to create a new listing on a mobile device is a key feature of the Multiple Listing Service system. Consider the information that must be entered when creating a new listing, and list the dialogue steps that are necessary. Keep in mind that when designing for a smartphone, less information can be entered in each step compared with a full screen Web application. Also keep in mind that typing is error-prone and awkward for many users, so think about opportunities to use check boxes, radio buttons, and list boxes to aid selection. Create a storyboard of this use case for a mobile device, showing each step of the dialogue that maximizes the use of check boxes, radio buttons, and list boxes.

Consider the case study for the Community Board of Realtors system on page 253.
