Business Process Architecture
Define process flows:
P2P (Procure-to-Pay)
O2C (Order-to-Cash)
R2R (Record-to-Report)
H2R (Hire-to-Retire)
SCM / Manufacturing
Projects
Contracts Etc
Deliverable:
End-to-end process maps
RACI matrix
Control framework
Application Architecture
Application architecture in an Oracle ERP implementation defines how the enterprise applications are structured, deployed, integrated, and managed to support core business operations. It ensures scalability, performance, security, and seamless interaction between users and backend systems.
Oracle ERP architecture typically follows a multi-tier model that separates presentation, application logic, and data management layers for optimal efficiency and flexibility.
Oracle EBS (On-Premise)
Application Tier
Database Tier
Concurrent Manager
Custom Objects
Interfaces
Oracle Fusion (Cloud)
SaaS Modules
PaaS (if extensions needed)
Oracle Integration Cloud (OIC)
BI Publisher / OTBI
Role-based security
Integration Design
Inbound integrations
Outbound integrations
Middleware (OIC, SOA, APIs)
Legacy systems
Bank interfaces
Payroll integration
Deliverable:
Interface inventory
Data flow diagrams
Error handling strategy
Data Migration Strategy
Data objects (Customers, Suppliers, GL balances, Open PO, etc.)
Historical data vs Open balances
Data cleansing
Validation approach
Tools:

Data roles
Deliverable:
Security matrix
SoD conflict report
Reporting & BI Design
Financial reports:
Operational dashboards
Regulatory reporting
Custom reports
Tools:
BI Publisher
OTBI
Smart View
FRS
DETAILED DESIGN (Refinement Phase)
Configuration Design

Testing Strategy
SIT (System Integration Testing)
UAT (User Acceptance Testing)
Regression testing
Performance testing
Security testing
Deliverable:
Test scripts
Defect log
Sign-off document
Cutover & Go-Live Plan
Final data migration
Open balances upload
Freeze period
Production validation
Hypercare support
Oracle Upgrade Strategy
An Oracle ERP upgrade strategy provides a structured approach to moving from an existing system version to a newer release while ensuring business continuity, data integrity, and minimal operational disruption. Upgrades help organizations leverage new features, improved performance, enhanced security, and regulatory compliance.
Oracle ERP Upgrade
Steps:
Technical upgrade
Custom object impact analysis
Database upgrade
Functional regression testing
Patch validation
Risks:
Customizations break
Performance issues
Integration failures
Oracle Fusion Quarterly Updates
Impact analysis
Sandbox testing
Regression testing
BI report validation
Security review
Best Practice:
Maintain test environment
Use release readiness documentation
Validate integrations
EBS to Fusion Migration (Transformation)
EBS to Fusion Migration (Transformation) is the strategic process of moving from Oracle E-Business Suite (on-premises ERP) to Oracle Fusion Cloud ERP. This transformation modernizes enterprise systems by replacing legacy infrastructure with a cloud-based, scalable, and continuously updated platform.
Approach:
Current state assessment
Gap analysis
Fit-to-standard workshops
Data cleansing
Integration redesign
Reporting redesign
Change management
Oracle Governance Framework
Steering committee
Change control board
Risk management log
Data governance
Audit compliance
Major Risks in Implementation
Poor COA design
Incomplete data migration
Weak SoD controls
Over-customization
Integration failure
Inadequate testing
Poor change management
