Enterprise Resource Planning (ERP) Overview

Enterprise Resource Planning (ERP) Systems

• ERP systems are software solutions designed for organizations across various industries, regardless of their size.
• These systems integrate and support core business functions, such as procurement, sales, finance, HR, manufacturing, production planning, logistics, and warehouse management.
• ERP systems are essentially a suite of integrated applications facilitating data collection, storage, management, and interpretation across different functional areas.
• Key functional areas covered by ERP systems include:
  • Financial Accounting
  • Human Resources
  • Customer Relationship Management (CRM)
  • Sales and Distribution
  • Logistics and Warehouse Management
  • Manufacturing and Material Management
  • Supply Chain Management
  • Business Intelligence

History and Evolution of ERP

• The concept of integrated solutions originated with systems for specific areas like Material Requirement Planning (MRP) for material management and Manufacturing Resource Planning for manufacturing.
• The term "ERP" was first used by Gartner Group in the early 1990s.
• By the mid-1990s, ERP systems addressed all core enterprise functions.
• Initially, ERP solutions focused on automating back-office functions, but later expanded to include front-office functions like CRM and e-business systems.

Benefits of ERP Systems

• Integration and Efficiency: ERP unites and links different business processes, optimizing overall business operations.
• Automation and Tracking: Automates various functions, enabling better order tracking, invoice processing, and cash receipt tracking.
• Centralized Data: Provides a single data repository, eliminating the need to synchronize changes between multiple systems and offering a unified view of business information.
• Data Security: Reduces the risk of data loss through a centralized data repository, when implemented with appropriate security measures.

Drawbacks of ERP Systems

• Complexity and Customization: Can be complex and challenging to customize to meet the specific needs of individual businesses.
• Training and Policy: Requires significant investment in continuous training for IT personnel, and needs a strong corporate policy for data integrity and usage.
• Business Process Re-engineering: Often necessitates re-engineering business processes to fit the new ERP system, which can disrupt existing workflows and impact staff.
• Cost: Can be expensive to implement, especially for larger organizations.
• Security Risks: Centralization of data increases the risk of information loss in case of a security breach.

Decision Support Systems (DSS)

• DSS are interactive, software-based systems designed to assist managers in decision-making.
• They leverage information from various related information systems, like office automation systems and transaction processing systems, to analyze vast amounts of data.
• DSS utilizes summary information, exceptions, patterns, and trends from analytical models to support decision-making.
• While DSS helps in decision-making, it doesn't provide the decision itself.

Characteristics of DSS

• Supports decision-makers for semi-structured and unstructured problems.
• Assists managers at various levels, from top executives to line managers.
• Supports both individual and group decision-making.
• Facilitates interdependent or sequential decisions.
• Supports intelligence, design, choice, and implementation phases of decision-making.
• Adapts over time to meet changing needs.

Classification of DSS

• Text Oriented DSS: Relies on textually represented information, enabling document creation, revision, and viewing.
• Database Oriented DSS: Data stored in a database is a major element, facilitating structured and organized data access.
• Spreadsheet Oriented DSS: Uses spreadsheets to create, view, modify, and execute self-contained instructions.
• Solver Oriented DSS: Employs algorithms and procedures for calculations and specific program types.
• Rules Oriented DSS: Follows defined procedures and rules. Expert systems are an example.
• Compound DSS: Combines two or more of the above structures.

Types of DSS

• Status Inquiry System: Supports operational, management, and middle-level management decisions, such as daily job scheduling.
• Data Analysis System: Facilitates comparative analysis using formulas or algorithms, for example, cash flow or inventory analysis.
• Information Analysis System: Analyzes data and generates informative reports, such as sales analysis, accounts receivable systems, or market analysis.
• Accounting System: Tracks accounting and finance information, encompassing final accounts, accounts receivables, payables, etc.
• Model Based System: Utilizes simulation or optimization models for decision-making, often used for general guidelines for operations or management.
