There are a couple methods to read the presenter's abstracts.
One method is to use the agenda search tool at http://www.plmworld.org/2016_agenda_search to generate a list of results. Then click on the hyperlinked titles to view more about the abstract and the presenter.
A second (and better) method is to use the Agenda Builder at http://www.plmworld.org/2016_registration under the "View Your Registration Details & Update your Agenda" link to build your daily agenda. There you can view all abstracts for all sessions in every time slot to help you determine quickly which sessions you'd prefer to see and at the same time create your own personalized agenda that you can print or download.
When you click on the 'Edit Agenda' button, you gain access to create/modify your agenda. Then for every time slot you are interested in, you click on '[Click to add session]'. Then you will see a pull down menu of titles to choose from.
