Q&A
STEP- C Objective
UK Higher Education has been facing challenges since last few
years. A few amongst them are:
• UK HE organizations have adopted “best of breed” approach
for acquiring information related to student. Each institution
then has to integrate the various application systems and
develop over-arching management reporting systems.
• There was a need for information to be acquired and
integrated across multiple Institutions to satisfy legislative
needs.
• UK legislation (anti-terrorism rules) require all UK Universities
to be able to monitor whether students who have obtained a
visa to attend an educational course are actually attending
and studying.

Implementation Benefits
• The solution is deemed to be technology and platform
independent
• The total solution is a loosely coupled architecture that any
systems can be added to the existing frame work without
disturbing the current environment.
• The reusability concepts of the SOA based architectures are
implemented by consuming all the functionalities as services
through the ESB.
• The development time to add new systems is very less as
retesting the existing solution and recompilation of the total
solution for minor changes can be avoided.
• With the concepts of Itineraries the data flow can be defined
by a business analyst without knowing the underlying
implementation of the any tool.

STEP-C Background
Each of the 167 UK HEIs have application architectures built with
•
Different combinations of ‘Best of Breed’ applications
•
Applications that are linked with point-to-point interfaces
•
Few “standards” for interfaces which are shared across the
entire sector
Hence, each University has a different starting point and also a
different size of IT department
