IBM Application Delivery Foundation for z Systems V3.0
Success story at a large European Bank
Driving faster innovation in banking and customer
services with IBM z Systems – Service innovation is a
major driver of competitive differentiation in banking. To
maintain first-mover advantage and win market share,
the Bank needed the ability to develop and test
software faster.
Why choose IBM ADFz?
§ Enhances visibility of performance and availability in
development landscapes
§ Accelerates z Systems development contributing to
first-mover advantage for the bank
§ Simplifies development with standards-based
graphical environment
“What’s great about ADFz and IBM Developer for z
Systems is that almost everything we need to deliver
software rapidly is in one interface” says Lead Software
Engineer and Technical Architect
“We continue to work closely with the IBM labs, in
particular to inspire them to incorporate our home-
grown functionality into the IBM tools. It’s a great two-
way relationship, and we appreciate the cooperation.”,
Senior Development Manager

IBM Developer for z Systems Enterprise Edition V14.0
Canada Mortgage and Housing Corp. – Improves efficiency and responsiveness
“We can be more responsive to the business, and we’ve gained that agility
we need to keep up with changing regulations.”
—Jeff Blackadar, application development manager
The transformation: Canada Mortgage and Housing Corp. (CMHC) was at risk of losing talent
because many of the programmers supporting the organization’s flagship COBOL application were
approaching retirement. To modernize its development environment, the company implemented
IBM® Rational® Developer for z® Systems software, which helps programmers maintain COBOL
code in an environment that looks similar to Microsoft .NET or Java environments.
Increases efficiency
by supporting hybrid developers
who can work across different application platforms
Helps programmers
without extensive COBOL experience maintain
COBOL code in a familiar development environment
Cut down a backlog of work
from years to less than six months

IBM Debug for z Systems V14.0
Success story with the next generation z/OS debugger
• An European financial services company uses a large number of
Enterprise PL/I batch programs to process data stored in DB2.
• With expected increase of data to process in coming years, it was
evident that their batch applications will eventually run out of virtual
storage in near future.
• The customer approached IBM to develop a solution which enables
exploitation of 64-bit virtual storage from their Enterprise PL/I
applications.
• Given the importance of suitable development tools, the customer
approached IBM to ensure development tools are enhanced
(specifically Debug Tool for z/OS as the priority) to enable debugging
of their 64-bit applications.
• In collaboration with the customer, IBM z/OS debugger team
delivered a solution which satisfies the customer’s requirements.
