We've just published a new white paper on the cool things you can do to create a rich, compelling user experience with the PeopleSoft Applications portal. This paper illustrates many of the things that are possible with a bit of web design and configuration--not customization! We also cover Workcenter pages, which is a new role-based portal framwork that comes with PeopleTools 8.51 and above. WorkCenter pages provide a more streamlined user interface for PeopleSoft applications, reducing the need for navigation, while increasing productivity by providing a central place from which the day-to-day work can be performed.
