Reverse Engineering of Applications through Peoplesoft Upgrade

Reverse Engineering of Applications through Peoplesoft Upgrade

The Client

 

A Life Insurance/Financial company primarily serving personnel associated  with  US  Armed  Forces,  offering  a  wide  range  of  products in banking, insurance and investment services.

 

 
Background
By 2001, took a strategic decision to strengthen its IT outsourcing  model and to extend it to offshore sourcing. This was driven by a need to reduce costs, to ensure that IT was strongly aligned to its business and to improve service delivery. The company chose HCLas its offshore partner.

Challenges / Objectives
  • Reverse engineering of Financials Processes to replace existing mainframe processes - The old mainframe system with extensive hard coded logic was used to push data in PeopleSoft Financials, so users were unable to configure it  according to day to day business needs
  • Error reporting was not present, so inadequate exception reporting often took valuable time in troubleshooting and timely  execution of processes
  • Provide a new end user maintenance facility which would allow  maintenance of supporting tables and the System should be able to merge with the environment post upgrade with no extra effort. Provide technical support during the porting and implementation of the new proposed PeopleSoft system.

HCL's Solution / Role
Based on  our  understanding we  presented three alternative feasible solutions:
  • The PeopleSoft Integrated Solution: This solution replaces the PL/1 logic with a PeopleSoft GL front End, where PeopleSoft will also  handle  the  UI  for  the  Business  Rule  tables  and  report generation.  The  client  chose  this model  after  discussions  and  analysis with HCL
  • The  Informatica  Integrated  Solution:  In  this  proposal  the Informatica ETL repository manages the data fed into the GLwhile the  Business  Rule  tables’ maintenance  as  well  as  report  ?generation is managed via Java
  • The  Informatica/PeopleSoft  Integrated  Solution:  This  solution replaces  the  PL/1  logic  with  an  Informatica  ETL repository. However,  the  UI  for  the  Business  Rule  tables  and  report generation will be handled within PeopleSoft.
 
We used PeopleSoft technology (PS Financials 8.0 SP2, People Tools 8.17) to implement the solution; The Application Engine was used as the integration tool; Crystal for reporting; VSS for version control; In-house quality tools to capture quality matrices; and FTP server to transfer the data.

Results / Benefits
  • Cost reductions have been achieved
  • PeopleSoft Technologies have replaced hard code programs
  • Provided externalized Business Rules using PeopleSoft Control Tables
  • Better Error Capture, Data Validation and Exception Reporting
  • Customer satisfaction has dramatically improved
  • Future complex projects are now jointly planned, managed and implemented by the client and HCL

Testimonial
 
"You've  really  put  in  great  effort  and  have shown a lot of patience and perseverance.  I am so excited about what you all have accomplished.  This improved  timeliness regarding  data  delivery  to  the LOB’s  ledgers  will  provide  users  with  iClienteased analysis time. What a great improvement!  Thanks for 
all of your hard work."  - CFO, Business Process Engineering
