Enterprise Resource Planning (ERP) and System Integration
- Enterprise Resource Planning (ERP) systems are integrated, multi-module software packages that support various business functions across an organization.
- ERP systems facilitate the collection and integration of information across different areas.
- They enable organizations to standardize and improve their business processes, helping implement best practices for the industry.
Enterprise Resource Planning (ERP)’s Role in Logical Integration
- ERP systems require organizations to focus on business processes rather than individual functions.
- They come with built-in processes for many common business functions.
- A good ERP implementation enhances operational efficiency by aligning business processes with organizational goals instead of focusing on departmental goals.
Enterprise Resource Planning (ERP)’s Role in Physical Integration
- Integration occurs at multiple levels:
- Data level → Consolidating all data resources into one database.
- Client level → Standardizing all client platforms.
- Application level → Ensuring a common user-interface design, back-end system access, and effective backup and recovery plans.
Enterprise Resource Planning (ERP) Architecture
- ERP system architecture is organized in layers or tiers to manage system complexity, providing scalability and flexibility.
- Can be broken down to ERP Modulesfor every business functions.
Implication for Management
- Enterprise architecture is crucial for the long-term functioning of an organization.
Complexity of ERP Architecture Decisions
- ERP architecture decisions are complex as they affect:
- Systems and technology.
- People, organizational policy, and business processes.
Role of Management in ERP Implementation
- Management must be involved in the design of the architecture from the start of the ERP implementation project.
- The system has wide and long-lasting implications for the organization.
