"We want developers to enjoy using mainframe
services. Opening up the mainframe using APIs
gives developers who are going to use mainframe
services a delightful experience."
-Ian Mitchell, IBM Distinguished Engineer responsible for z/OS Agility

professionals with cloud-native
development experience.
"Mainframes offer enterprises a
lot of value, but if that value can't be
unlocked to create new markets, or
to innovate, then the organization
is susceptible to digital disruption,"
says Rosalind Radcliffe, IBM Distinguished Engineer responsible for
DevOps* for Enterprise Systems.
"If an organization can move faster
without compromising the quality
of services needed, they can win in
any market."

dently transition to Agile, achieve
speedier outcomes and take full
advantage of a multicloud environment, Mitchell suggests focusing on
&É%ÉîÃ(ÉÃÄ$ÉÄ%P
1. Organizational
structure
"How teams are
organized, where
they are located
and how they work
together dictates
component boundaries,"
explains Mitchell. Conway's Law,
an adage named after computer
programmer Melvin Conway, purports that technical architectures
$ɯÃÉÇ&ÃÄ Ã!$Ä  Ä&! V%Ã%!ÇÄÃ
boundaries.
For IBM Z clients, two dimensions should be scrutinized. The
®Ã$%&Ã%Ã)É&É$Ã"É!"ÉÃ)!$ Ã! Ã
the mainframe platform are integrated with the rest of the organi-

zation. Development teams must
be integrated across the organization, not working in silos. If the
mainframe team isn't integrated
with the rest of the IT infrastructure, the transformation will be
painful. The second dimension is
whether all of the functions across
the lifecycle within the mainframe
team are integrated correctly (e.g.,
the developers, testers and production roles).
"Make sure your organization is
structured to get the right outcomes," notes Mitchell. "Successful
transformation requires both dimensions-gaining tops down and
bottoms up support is crucial."
2. Pipeline
Streamlining the
pipeline is the
second insight on
Mitchell's radar.
"The pipeline needs
to be made from common tools that cover the
entire lifecycle experience," he says.
"There's absolutely no doubt about
the value of the IBM Z platform
and the applications in terms of a
differentiated outcome. But nobody
is interested in the way you achieve
that outcome to be different."
Developers want more open
source and less proprietary,
mainframe-only elements. They
want to use tools like Jenkins to
manage the pipeline, automating the
different stages of the pipeline from

development, testing, through to the
deployment stage. Clients also want
the same basics in the development
experience. For instance, the editors
and source code management systems need to be familiar.
"Unfortunately, inertia can stop
people from modernizing. There's
no need to continue using antiquated tools for source code management," says Mitchell. By focusing
on reimagining their pipeline,
teams can use conventional processes and tools that allow them
to develop applications faster and
deploy those applications in any
cloud environment.
3. Testing
"Everybody
needs better
testing-through
automation,
repeatability and
transparency about
what's been tested, developers gain

is the only practical way developÉ$%ÃÄ ÃÇ! ®ÃÈÉ ÇÉà Ã)Ä&Ã&É1V$ÉÃ
doing. "It's vital that everybody on
the mainframe has the opportunity
&!Ã&É%&ÃÇ! & '!'%1QÃ&!ÃÄ(ÉÃÇ! ®ÃI
dence in the testing and transparency to ensure everybody knows
what's been tested."
Although testing automation
speeds things up, if clients aren't on
board with it-it slows them down.
Developer-centric test automation
is the key to ensuring the IBM Z
