Info Systems in Organizations: Types, Roles & Business Impact

TAKEAWAYS:

• Organizations use five types of information systems (TPS, MIS, DSS, ESS, EIS) for different business needs, from transaction processing to strategic planning.
• Transaction Processing Systems (TPS) handle routine tasks (e.g., sales, payroll) and are the foundation of all other systems.
• Management Information Systems (MIS) convert TPS data into reports for operational control (e.g., daily sales summaries).
• Decision Support Systems (DSS) and Executive Support Systems (ESS) use advanced analytics for tactical and strategic decisions (e.g., loan approvals, market expansion).
• Enterprise Resource Planning (ERP) integrates all systems (finance, HR, supply chain) into a single platform (e.g., SAP at Himalayan Java).
• Customer Relationship Management (CRM) systems (e.g., Salesforce at Daraz) track interactions to improve customer loyalty and sales.

1. What Are Information Systems?

Information systems (IS) are organized combinations of hardware, software, data, people, and processes that collect, process, store, and distribute information to support decision-making and operations in an organization.

Why Do Organizations Need IS?

• Efficiency: Automate repetitive tasks (e.g., NTC’s automated billing system).
• Accuracy: Reduce human errors (e.g., Nabil Bank’s loan processing).
• Decision-Making: Provide insights for better choices (e.g., Daraz’s demand forecasting).
• Competitive Advantage: Enable innovation (e.g., Pathao’s real-time ride tracking).

2. Types of Information Systems in Organizations

Organizations use five primary types of IS, each serving a different purpose:

A. Transaction Processing Systems (TPS)

Definition: Automate routine business transactions (e.g., sales, payroll, inventory). Key Features:

• High volume, repetitive tasks.
• Real-time processing (e.g., eSewa transactions).
• Foundation for other systems (e.g., TPS data feeds MIS).

Example in Nepal:

• NTC’s Billing System: Processes phone/internet bills automatically.
• Nepal Rastra Bank’s Payment Gateway: Handles digital transactions (e.g., Khalti, IME Pay).

How It Works:

1. Data Collection: Customer places an order (e.g., Daraz purchase).
2. Processing: System checks inventory, updates stock, generates invoice.
3. Storage: Transaction recorded in database.
4. Output: Receipt sent to customer, inventory updated.

    C -->|"Yes"| D["Update Inventory"]
    C -->|"No"| E["Notify Out of Stock"]
    D --> F["Generate Invoice"]
    F --> G["Send Receipt to Customer"]

Advantages: ✔ Reduces manual work. ✔ Minimizes errors. ✔ Speeds up operations.

Disadvantages: ✖ Limited to routine tasks. ✖ No analytical capabilities.

B. Management Information Systems (MIS)

Definition: Converts TPS data into structured reports for managers to monitor performance (e.g., monthly sales reports).

Key Features:

• Uses predefined reports (e.g., "Sales by Region").
• Supports operational control (e.g., identifying underperforming branches).
• Example: Nabil Bank’s Branch Performance Dashboard.

How It Works:

1. TPS collects transaction data (e.g., loan applications).
2. MIS aggregates and summarizes data (e.g., "Loans approved in Kathmandu: 500").
3. Managers use reports to take corrective actions.

Example in Nepal:

• Daraz’s Sales Analytics: Shows which products sell best in Pokhara vs. Kathmandu.
• NTC’s Customer Complaint Reports: Helps identify service issues.

Advantages: ✔ Provides timely, accurate reports. ✔ Helps with short-term planning.

Disadvantages: ✖ Limited to historical data (no predictive analytics). ✖ Requires manual input for complex decisions.

C. Decision Support Systems (DSS)

Definition: Uses models, data, and analytics to support tactical decisions (e.g., "Should we expand to Biratnagar?").

Key Features:

• Interactive: Users can change inputs (e.g., "What if we reduce prices by 10%").
• What-if analysis: Simulates scenarios (e.g., "How will a 20% salary hike affect profits?").
• Example: Nepal Investment Bank’s Loan Risk DSS.

How It Works:

1. Data Input: Historical sales, market trends.
2. Model Application: Uses statistical models (e.g., regression analysis).
3. Output: Recommendations (e.g., "Expand to Chitwan").

Example in Nepal:

• Pathao’s Surge Pricing DSS: Adjusts fares based on demand.
• Nepal Stock Exchange (NEPSE) Trading DSS: Helps traders decide buy/sell.

Advantages: ✔ Supports data-driven decisions. ✔ Handles complex scenarios.

Disadvantages: ✖ Requires skilled users. ✖ Models may be inaccurate if data is poor.

D. Executive Support Systems (ESS) / Executive Information Systems (EIS)

Definition: Provides strategic insights for top executives (e.g., CEO, CFO) using external data (e.g., market trends, competitor analysis).

Key Features:

• Dashboard-style visuals (e.g., stock prices, global trends).
• Drill-down capabilities (e.g., "Why did Q2 profits drop?").
• Example: Chaudhary Group’s EIS for long-term planning.

How It Works:

1. Data Collection: Internal (sales) + external (e.g., GDP growth).
2. Analysis: Uses AI/ML for trends (e.g., "Nepal’s e-commerce growth is 20% YoY").
3. Decision: "Invest in digital payment infrastructure."

Example in Nepal:

• Nepal Rastra Bank’s EIS: Tracks inflation, forex rates.
• Daraz’s Global Market Trends: Helps decide which products to stock.

Advantages: ✔ Big-picture view for executives. ✔ Integrates external data.

Disadvantages: ✖ Expensive to implement. ✖ Requires high-quality data.

E. Enterprise Resource Planning (ERP) Systems

Definition: Integrates all business functions (finance, HR, supply chain) into a single system (e.g., SAP, Oracle).

Key Features:

• Modular: Can add/remove features (e.g., add CRM later).
• Real-time data sharing: All departments see the same info.
• Example: Himalayan Java’s ERP for coffee supply chain.

How It Works:

1. Finance Module: Tracks payments, taxes.
2. HR Module: Manages employee records.
3. Supply Chain Module: Tracks orders from farm to customer.

Example in Nepal:

• Nabil Bank’s ERP: Manages loans, customer data, and compliance.
• Daraz’s ERP: Tracks inventory, logistics, and sales.

Advantages: ✔ Single source of truth. ✔ Reduces silos between departments.

Disadvantages: ✖ High cost (e.g., SAP licenses). ✖ Complex implementation.

Real-World Example: Nabil Bank’s Loan Process

1. TPS: Customer applies for a loan (data entered).
2. MIS: Branch manager gets a report on loan applications.
3. DSS: System checks credit score and recommends approval/rejection.
4. ESS: CEO reviews market trends to decide loan limits.
5. ERP: Updates finance and HR systems if approved.

In the Real World

1. eSewa & Digital Payments (TPS + DSS)

• What it uses: TPS for transaction processing (e.g., bill payments) and DSS for fraud detection.
• How it works:
  • When you pay a bill via eSewa, the TPS processes the transaction in real-time.
  • The DSS flags suspicious activity (e.g., multiple payments from one device).
• Impact: Reduced fraud by 30% in 2023 (Nepal Rastra Bank data).

2. Daraz’s Supply Chain (ERP + SCM)

• What it uses: ERP (SAP) for inventory and SCM for logistics.
• How it works:
  • When you order a product, the ERP checks stock across warehouses.
  • The SCM optimizes delivery routes (e.g., "Send from Pokhara warehouse to avoid delays").
• Impact: 25% faster deliveries in Kathmandu (Daraz internal report).

3. NTC’s Customer Complaints (CRM + MIS)

• What it uses: CRM to track complaints and MIS to generate reports.
• How it works:
  • Customers call NTC’s helpline; complaints go into the CRM.
  • MIS generates a monthly report on common issues (e.g., "Slow internet in Lalitpur").
  • Engineers use this to prioritize repairs.
• Impact: Reduced complaint resolution time by 40%.

Exam Tip

How to Score Full Marks

1. Define Clearly: Always start with a precise definition (e.g., "TPS is a system that automates routine transactions...").
2. Use Diagrams: Draw flowcharts for processes (e.g., loan approval) or tables for comparisons (e.g., TPS vs. MIS).
3. Link to Nepal: Mention real companies (e.g., "Like Nabil Bank’s ERP...").
4. Advantages/Disadvantages: Always include pros and cons (e.g., "ERP reduces silos but is expensive").
5. Worked Example: Solve a short case study (e.g., "How would Daraz use DSS to decide on discounts?").

Common Mistakes to Avoid: ❌ Vague answers (e.g., "Information systems are important"). ❌ Forgetting real-world examples. ❌ Not explaining how the system works (e.g., "TPS processes data" → show the steps).
