Typical Experience Until RecentlyTypical Experience Until Recently
Users logged on to systems and navigatedto find information or perform processes. training
Individual apps different sign-ons Poor/non-existent user interface standards
Or worse still, the system sent printed output
to them through snail-mail
The point is they usually had to overtly seekout the information in disparate systems*

Obvious advantages of buyingObvious advantages of buying

UT; PSU; IU; others Any English majors in the room?
To Buy or Not to Buy; that is the question;
Whether tis nobler in the mind to suffer the slingsand arrows of outrageous consultants fees;
Or to take up arms against a sea of vendors;
And by opposing, end their stranglehold.

CaveatsCaveats
Clear disadvantages to both.
Reality says you may have to
customize Worst of all worlds?
Compromised the value

Paying the vendor for the
vanilla system at every
new release and must re-
customize

OptionsOptions
More likely you will end up building, buying and
assembling
Loosely coupled systems are more and more the
future and thats why integration is key
Customization takes on a new form Based on what and who I am.driven by a directory.
Role based view; not everybody needs the entire SIS or
whatever

Componentsaka Web ServicesComponentsaka Web Services
Servers at the core of the network willincreasingly act as "facilitators" by guidingprocedure calls to the locations where theycan be most efficiently executed.
Given such capabilities, the emphasis ofsoftware development shifts to re-architectingbusiness functions into modular, network-enabled components spread across a highly-
distributed computing infrastructure. Thisevolution, more than anything else, is thefundamental driving force behind the WebServices architecture.

The official place to which the organizationwould send stuff it wanted you to address.

Why do we need a portal?Why do we need a portal?
What are the problems? Broadening base of information consumers
with varying levels of technical expertise. Students and faculty increasingly demand
mobile access to IT resources. Aging, monolithic or silod applications
Developed to serve specific audiences;
Current users must find and learn to useeach silo. Disparate information systems that lack
integration and flexibility;
Too complex for majority of end-users

Why do we need a portal? ContdWhy do we need a portal? Contd
Every new website is potentially a new silo
Age of disintermediation more of our students
expect to be able to do things for themselves.
Dealing with non-traditional campus communities in
traditional ways
Enable a more cost effective, nimble and sustainable
application development process.. and not just for IT
developers
Bottom Line: Trying to change theway the institution creates and
delivers e-Services

Enterprise Portal ROIEnterprise Portal ROI
Its about changing:
The way the institution does its business align with
the mission Some institutional behavior
It provides the best opportunity for enterprise
application integration
Portals encourage common development practices
etc. Development teams need not create their own individual(silod) solutions for each service
Developers can focus on actual services for their users

"You won't see a whole new array of things
that you couldn't do before because of Web
Services, but you'll see application
development enabled much more quickly,"says Larry Calabro, a partner in the
technology integration unit at Deloitte
Consulting in Chicago. Calabro says Web
services standards will make it easier forcompanies to build applications that more
effectively integrate existing software
packages such as CRM and ERP.

Gartner:Gartner:
By 2004, Web services will represent the
dominant mode of deployment for new
application solutions for Fortune 2000
companies (0.8 probability). True interoperability standards won't exist
in the portal product market until 2004,
forcing users to build "uberportals" to
integrate multiple portals within theirenterprises (0.7 probability).

AbstractAbstract
In this era of heterogeneous application services,the need to integrate these for members of theuniversity community has never been greater.Vendors promise integration and that solution
works for many institutions. For others, the singlevendor ERP direction is not an option or is not adesired strategy.Enter the enterprise portal. Properly architectedand supported, it can provide a sustainableplatform for delivering Enterprise ApplicationIntegration (EAI).
