Top 3 Benefits
Of Re-Architecture
Future Ready Systems with reduced development
cycle
Easily scalable to current and future market
demands
Re-use existing enterprise assets with easier
extensibility and lower costs
Top 3 Reasons
for Re-Architecture
Rapidly changing Industry Standards and
regulations
Unable to scale functionality to meet increasing
demands
Changing business process in a replicated
environment is tedious and time consuming
Market Cycles are becoming increasingly shorter and companies needs to make Business critical decisions faster
It is crucial to maximize the value of the application by reducing the cost of ownership and by developing agility by aligning technology with business imperatives
Syntel’s Legacy Re-Architecture Service enables customer to remodel and optimize their existing business process and migrate from legacy systems to Modern Agile systems
Syntel’s Legacy Re-Architecture Philosophy

securities to investors
backed by these
receivables.
• ABS is responsible for
generating 30% of all debt
for organization
Business Drivers

requires lead time of over 18
months
• Enhancing liquidity in existing
trust requires minimum of 6
months
• Inability to securitize Small
Business & Corporate portfolios
• Inability of system to scale up for
high volume of data
• High turn around time for resolving
month end issues

subsequent phases which saved
cost
• Engagement : 5+ years
Outsourcing Models: T&M
• Offshore :Onsite ratio: 80:20
• Team size: 100+
• Target platform: File based
System was converted to DB2
Challenges Faced
• Stringent timeframe as
business wanted to tap the
securitization market -
Phase wise approach based
on priority
• Old complex programs had
to be deciphered - Detailed
design documents
• More than 100+ new reports
had to be created –
Reusable components for
reporting
Syntel Solution Proposed securitization of Corporate portfolio along with OSBN resulting $11 Billion additional
contingent liquidity.
Proposed a new system flexible to include securitization of future portfolios, ex: International accounts that will result in additional $10 Billion contingent liquidity.
The initiative will provide 35% increase in liquidity for the customer
ABS to own all data pertaining to Securitization, hence the data dependency on AR system will be eliminated thereby considerably reducing the lead time for securitization, new product launches.
Provide business with capability to create their own reports by introducing BI reporting tool (Cognos 8.0, first team to implement in AMEX).
Enable Daily Centric processing moving closer to Daily Settlement
Customer Benefits• Reduced total turn-around for Securitization
of new Portfolios from 18 months to 5 months.
• Reduced total turn-around time for Securitization of accounts from 6 months to 1 month.
• New product launch for of $11 Billion and enabled system for future ABS reduced from 2 months to 5 days.
• Additional contingent liquidity of $10 Billion
