Information systems

Overview of Systems and Their Interactions

The focus is on various IT systems and how they interrelate within an ERP (Enterprise Resource Planning) system.

Customization Systems: Tailored systems for specific business needs.
Supply Chain Systems: Manage the flow of goods, information, and finances.
Human Resource (HR) Systems: Allow employees to check base leaves and company rules.
Customer Relationship Management (CRM) Systems: Focus on managing a company’s interactions with current and potential customers.

Definition: CRM is a system that manages a company’s communications and relationships with customers.
Functionality:
- Stores customer details.
- Personalizes marketing offers based on purchase history.
- Example: If a customer buys coffee, they may receive notifications about discounts on that coffee or other related products.
- Amazon uses similar data to recommend products to customers based on their purchasing patterns.

Definition: SCM involves managing the flow of goods and services, including all processes that transform raw materials into final products.
Functionality:
- Automatically triggers orders when stock is low.
- Example: Checkers will reorder an item like tasty grass when inventory is low or if bad reviews of a supplier's products have been reported.
Market Strategy:
- Adjust pricing for items nearing expiration to encourage clearance before spoilage (e.g., discounting perishable items).

Enterprise Resource Planning (ERP) System: Integrates various business functions into one complete system.
Cross-Functional Nature:
- Characteristics include breaking down silos between departments (e.g., HR collaborating with Supply Chain).
Centralized Database:
- Ensures all updates are reflected uniformly across the organization, providing a single source of truth.
- Avoids the issues of distributed databases where information could require manual updating and reconciliation.
Efficiency and Maintenance:
- ERP systems enhance efficiency, make information readily available, and are easier to maintain, but they are expensive and time-consuming to implement.
Implementation Considerations:
- Companies can opt to build a custom ERP system or purchase an existing one and adapt it to their needs. The decision often hinges on how quickly a solution is required.

Definition: TPS handle day-to-day transactions within a business, updating records in real-time.
Features:
- Online processing capabilities.
- Provide real-time data, enabling insight into stock levels and sales trends.
- Can recognize inventory losses due to theft or error, and highlight discrepancies between expected and actual stock.
Example: The TPS can identify theft if stock levels do not match sales data.

Types:
- Transaction Processing Systems (TPS)
- Process Control Systems: Manage manufacturing processes and operational efficiency.
- Office Automation Systems: Automate routine office tasks to improve productivity.

Role in Manufacturing:
- Involves decisions on production scheduling and pricing based on material quality and supply chain dynamics.
- Example: The choice of leather vs. synthetic materials can affect the pricing of products like car seats due to perceived quality.

Emphasis on group work for research and discussions to enhance understanding.
AI Usage in Assignments: Students should disclose AI assistance in their work.
Test Preparation:
- Review previous learning units and slides before the upcoming test.
- Engage in discussions to solidify comprehension of the material.
