"New code costs 5X reusing existing code" SW Productivity Research40 – 60% may be reusableReduce costsAchieving faster time to market

Significant business intelligence exists in legacy Systems"200 Billion lines of COBOL/RPG code in existence" eWeek"5 Billion lines of COBOL/RPG code added yearly“ Bill Ulrich, TSG Inc."Between 850K and 1.3 Million COBOL/RPG developers" IDC"Majority of customer data still on mainframes“ Computerworld “Replacement costs $20 Trillion” eWeek

Rewriting - is it an option.....How long will it take? (lose strategic benefit)Who will do it? (who has the business knowledge?)How much risk and cost are involved?

HATS Scenarios: Add business logic with Java Beans

HTML 3270, 5250

Customer Java bean

Use Customer provided bean to add business logic to HATS flow, Use HostPub Integration Objects to augment the HATS flow

This example HostPub queries secondary application and provides input to HATS flows

Calendar ControlThis calendar control is not built into HATS; however, it does show the power of working in an open environment where 3rd party components (a freeware calendar control in this case) can be used.

Use HATS to produce business value and ROI

HATS can streamline the flow through existing applicationsƒ Combine screensƒ Skip screensƒ Automate screen-to-screen navigationƒ Save and input global variables

Benefitsƒ Reduce the number of keystrokes and workflow stepsƒ Reduce transaction timesƒ Reduce employee training timeƒ Increase employee job satisfaction and retention

HATS can get information and self service transactions on to the web quicklyƒ Web-enable existing transactionsƒ Increase reach and availability

Benefitsƒ Increased information and service to customers, employees, dealers, vendorsƒ Cost reduction, e.g. offload call centers

Host connection to your TN Server remains within the firewall Clients can connect to your host system from the Internet or intranet Host and TN Server remain secure inside your firewall

End-to-end SSL encryption Integrate with your existing authentication Restrict content from the original applications

Reduce data on individual screensOr prevent access to parts of your application

Secure Your Assets

Let HATS handle the "dirty work"

Easily provide printing from web apps HATS uses existing host print function to produce .pdf print files

Deploy WAS-based web applications that leverage the mainframe rather than duplicating mainframe data in distributed databases

IBM Software Group


Who can leverage HATS?

Any department or enterprise that needs to:–Extend their business to the web

ƒ Provide information and applications to new end users

ƒ Combine existing information in new formsƒ Replace dial up connections with the Internetƒ Communicate more efficiently with Branches, Agents,

Dealers, Stores, Franchises, Distributorsƒ Establish Internet communication with customers, policy holders, citizens, the general public...

–Modernize and streamline the interface and workflow of

existing applications, e.g. Call Center applications

IBM Software Group


Where can leverage HATS be leveraged?Applications with high transaction volumes and/or many end users

ƒ Reduce keystrokes, workflow steps, transactions timesƒ Reduce training costs

Call center and voice response unit applicationsƒ Offload to web self service transactions

Information and applications that need to be "externalized" to the webƒ Use existing applications to speed the implementation to the webƒ Provide access from any browserƒ Intuitive web pages eliminate need for costly user training

Administrative applications used by most employeesƒ Human resources applications, job posting, insurance changes, benefits enrollmentƒ Procurementƒ Time and attendance, Travel and living expenses

Information to be combined and summarized for executive reviewPortals
