Select “Browse” at the bottom, and find “Rational_Standard_Template.pot” on your hardrive and click Apply
Please note that not all slides will reformat appropriately once template is applied. Some reformatting will be necessary
Printing your presentation on a black and white printer
Prior to printing your presentation, view the slides in grayscale mode: Select View / Color/Grayscale / Grayscale
Select problem graphics or text and right-click and select Grayscale Setting
Select the grayscale setting that displays the problem graphic/text the best
Note: Changing the greyscale setting does not affect the color view

2. “I can’t even work on Mondays! Production workload kicks me off.”
Business constraints with mainframe development today Which limits the amount of System z production workload coming online
“Operations tell me it will take two months to get my test system allocated.”
“My development capacity charge-back is consuming my entire budget. I can’t spend on tools.”
“I can only test my batch applications in offline hours. Online apps consume the 9-5 cycles.”
“We don’t have the capital budget to obtain more mainframe test resources for my developers. It’s easier and cheaper to get a Windows or Unix box.”
“It is difficult for my developers to learn the mainframe. Operations controls can prevent experimentation by developers..”
IT Skills concerns  Improve approachability of the platform
IT Productivity concerns  System staff less responsive than desired in balancing AD vs. production requirements
Mainframe capacity limits  capital constraints on new hardware can limit the amount of time developers have on systems (e.g., Monday morning batch workload window problem)
New workload models (Retain existing application workload)  Developers expect easy access and configuration of unit testing on workstation (e.g., WebSphere unit test environment)
IT Cost containment  Lower cost of unit testing by offloading unit test cycles to lower cost platforms
Supporting Analyst Thoughts
1.5 Million COBOL developers declining 5% per year – Gartner
We need the enhanced productivity of developers being in control of unit testing. - Minnesota customer purchasing MicroFocus
RDz is more productive than MicroFocus although they are leader for local development - Norwegian University Study
We need to be in control of unit testing. Our systems programmers don’t have the time to respond to our requirements for hundreds of CICS regions, databases, etc. - RBSG
There is a chasm between the Developers and IT Operations staff
Developers don’t have control of non-Intel systems
The ability to easily configure and deploy an application to the target runtime for testing proves to be very programmer time-consuming task as well as the ability to automatically test the resulting application/service. This is accentuated when considering composite applications consisting of WAS and another platforms’ runtime.
The development environment is perceived as more expensive on System z then on intel
Another aspect of this is that there is no differentiation of mip costs between development mips vs test mips vs production mips.
Some customers expect development/test mips should be less expensive since high QOS is not required.
“I can’t even work on Mondays! Production workload kicks me off.”
“I want to try out creating Event Processing and ATOM apps, but my system isn’t scheduled for a CICS update till 2013.”
“The Mainframe isn’t cool anymore. It’s faster and cheaper to develop on a Unix platform.”
