Why modernize my green screen?
• “If it ain’t broke…”
• “Only our call center uses it. … “
• “It’s a 3rd party app”
• “I’ve used it for 20 years.. Nothing wrong with it!”
• “We don’t need to integrate it”
• “Too much invested in it to throw it away”
• “But it has all our business rules!”
• “We’re going to all .NET …..next month”
• “We spent too much training everyone on this
system”
• “Joey retired and we lost his member files”
• “I’m retiring next year, what do I care?”

Business Challenge: Data Entry Errors
• Terminal Apps offer poor data entry controls
• Garbage in – garbage out
• Poor data entry results in:
– Inaccurate business intelligence
– Giving the customer or patient the wrong order
– Longer call times
– Loss of productivity due to data re-entry, or data correction
– Having to purchase additional software to correct errors (i.e. Infosphere
QualityStage, Optim, etc)

Business Challenge: Longer Training Time
• Non-intuitive interface
– No tool tips, context sensitive help, coded fields, abbreviations, etc.
• Current generation knows the web
– Does NOT understand „field exit‟, „clear‟, etc.
– “Where is the PF3 key?”
• Training is often a neglected item in IT budgets
– “Isn‟t that what consultants are for?”
• Average annual turn over in a call center is 33%*
– Longer training required == less productivity, greater cost per resource

Business Challenge: User Frustration
• Poor field labels
• No ‘hints’ on field controls
• Lack of access to documentation
• Complex navigation
• User workflow that does not make sense
• Post-it notes around the monitor as
‘documentation’
• Multiple windows
• Poor printing capability

Business Challenge: Lack of Access to Source Code
Columns . . . .: Edit
SEU ___________________________________________________________
-----------------------------------------------------------------
• Common with COTS applications
• Legacy apps from acquisitions
• Required use of a partner, vendor, or parent company application
• Developer lock out
– You fired the guy who had the code, he deleted it as he walked out
• Changes to source may involve costly risks
– “Everything is tied to our ERP!!”

Business Challenge: Need a modern experience NOW!!!

• Heavy load on testing
• Large cost involved in retraining

•HATS toolkit plugs into
Rational Application Developer
• Benefits:
• Harness existing skills
• Simplify deployment

Improving data entry accuracy
• Calendar drop downs ensure date formatting
• Radio buttons eliminate non-valid values
• Drop downs give the user legible options
– Avoid post-its around the monitor to decipher field label values
• Dojo enabled widgets
– Easy to inject client side validation
– Type ahead features make it easier to find values in long lists

Improving the user experience
• Macros improve navigational flow
• Replace acronyms, & codes with real legible field labels
• Clickable buttons & links replace function keys
• The more intuitive the interface, the less demand for documentation (or
the less it gets used)
• Dojo layout widgets better organize the screen
– Tab, accordion, stacked containers organize fields appropriately
• Print directly from the browser
– Use “print” style sheet where needed

Reducing training time
• Leverage web browser familiarity
• Make labels & field options readable
• Client side validation gives instant feedback.
• Reduce training time by up to 75%
• Make it intuitive!
• Example: Has anyone ever taken 3 months to train on Facebook, Gmail, or other popular sites?
– Anyone ever seen the documentation?

Iteratively improve the application as you go
Today Day 1 Tomorrow
Instant Value: HATS default
rendering automatically
transforms actions into
clickable links and buttons. No
changes required to the host
application.
Modern UI: All
pages share the
same theme and
style, which can be
based on an existing
Web site.
Aggregation: data from
other
screens, databases, or
other systems can be
merged and displayed
with host data.
Integration: Text can be
replaced with images, input
fields can be populated from
data on other screens or from
a database, date fields can be
converted into popup calendar
widgets, and more!

No need for access to RPG/COBOL code
• Rendering engine transforms the Data stream on the fly
– 5250 , 3270, VT100
• Does not access display files, or file members
• Multiple panes of data – not a screen scraper
– Text, Field, DBCS, Color, Extended Attributes, Grid

Solution:
Using System Z for all manufacturing applications, HR applications. Using HATS to provide web services for
WebSphere Portal based dealer management system.
Benefits:
$13K less annual paper/communications
$65K/yr annual labor costs
Improved Employee productivity

Case Study: Total System Services (TSYS)

Company Background
 Ticker: TSYS
 Largest (publicly traded) Electronic Payment Processor in the World
 Based in Columbus, Georgia
 TSYS is the only company with a single platform capable of serving a
client's portfolio on more than one continent
 VERY large mainframe footprint
 At one point was the 3rd
largest in the US

Business Challenge
 Very large host based applications (TS1/TS2)
 Services the credit/debit card industry
 These are the systems service reps use when you call your bank
 Account balances, payment history, card activations, etc.
 1000's of 3270 green screens
 Highly available, secure encrypted communications to customer premises
 Very complex business logic
 > 50,000 users on these systems
 18M 3270 screens displayed per day
 TS1 in operation for decades, TS2 since 1994
 Both offer different services depending upon retail, commercial, debit, or credit customer
 Tiered service offering
 3270 Green Screens ($)
 ProphIT (.NET) – no custom workflows ($$)
 ProphIT with custom .NET, MQ/CICS workflows ($$$$)

Business Challenge
• Need to replace the interface for lower tier offerings
• Gradually losing customers to competition
• Competition has Web or Rich UI
• Less expensive, more features than TSYS' low tier offering
• Top tier offerings still require 3270 for some functions
• Very high training costs
• ~90 days to bring a new CSR up
• Average turnover of 10-12 months
• 7-9 months average productive time
• Expensive and risky to replace TS1/TS2
• Strict SLA's, Sarbanes-Oxley, SEC, Financial regulations
• ProphIT originally meant to replace the UI

Technical Challenges
• 1000's of screens
– About 10% used 90% of the time
• Complex business logic
– CICS, multiple regions, highly customized RACF
• Tight real estate on the screens
– Many fields are coded results
– Many field labels are abbreviated/coded for space
• EXTREMELY tight security
– No external parties can connect to their internal network
– TSYS development teams cannot connect to external networks
• Little to no in-house expertise in Java / Java EE
– .NET one side, Cobol/Assember on the other

AFTER

Previous Solutions – ProphIT
• Key revenue stream for top 2 tiers
– Originally intended as a UI replacement
– Serves as the top 2 tiers for credit/debit card servicing
• Microsoft .NET Based
– Custom work flows
– Headless MQ/CICS transactions
– 150+ developers
• Each customer gets their own rack space
• >$30M initial development cost
• Handles 20-25% of TS1/TS2 functionality
– 95% of CSR's time spent in ProphIT
– Remainder using green screens

Alternatives Considered
• Seagull Software
– Closest competitor to HATS
– Does not support RTL languages (i.e. Arabic, Hebrew)
– Recent change of ownership with no clear future strategy
• Pegasus Systems
– True screen scraper
– No way to combine screens
– Not mature product, poor documentation
• Microsoft Host Integration Solution
– Similar to features already used in .NET with MQ transactions
– API based

New Solution
• Initial Proof of Concept
• Pilot for single new customer
– Our consultancy trained TSYS in-house personnel and performed initial implementation
– Wildly successful
– One of the fastest deployments IT had done
– Sales and marketing group highly interested, ready to sell
– Set a precedent for all other departments to match
• Conversion to beta for group of key customers
– Some new, some old customers
• Transition to major project within IT division
– Goal to replace Tier1 offering with HATS based UI
– No more 3270 offerings except for specific security needs
– All web based, no RCP or Mobile

Implementation/Architecture
 Host Access Transformation Services
for 3270 Applications 7.1
 WebSphere Application Server ND 6.1
 IBM HTTP Server
 Cisco Load Balancers
 Rational Application Developer
