Key Services

• Portal: a user-centric web desktop that gives users access to

all of the information resources they commonly use.

• Workflow Service: General purpose service that automates

the routing of documents to the users responsible for working

on them.

authorized application or user can reliably notify a user of a

task, an alert or an event.

uPortal usage

• Current usage– All students– Most Faculty– Some Staff

• Find ways to engage more of our staff community

• Admin Fragment– Currently lists of links– How can we add more functionality

uPortal usage

• The more content we put there the more people will use it; the more they use it the more content providers will want to provide rich content

Workflow

• Kuali Enterprise Workflow• A major hook for Administrative users• Action list in the portal• If people are already looking at their action

list, can we add even more value?
