Suppose you're an employee at Adventure Works, and you want to see contacts grouped by standard information in them—for instance By Company or By Location. You can do this simply by selecting one of these built-in views in the Navigation Pane.
Outlook creates these groupings from the information already entered about the contacts. For example, the picture shows a view that groups contacts by their companies. If you want to see a list of all your contacts at your supplier Alpine Ski House, that's as easy as clicking By Company in the Navigation Pane.
