Unit 6 Intro: Information Systems within Organizations
IT 233: Business Information Systems
Learning Objectives
By the end of this introductory chapter, you will be able to:
✅ Differentiate between the major types of information systems used within an organization.
✅ Explain the foundational role of Transaction Processing Systems (TPS).
✅ Describe Functional Area Information Systems (FAIS) and the challenge of "information silos."
✅ Define Enterprise Resource Planning (ERP) systems and their purpose in business integration.
The IT Landscape is Not Flat
Organizations are complex, and their information systems reflect that. Systems are tailored for different needs.
Different Levels, Different Needs
Operational: Day-to-day activities.
Managerial: Mid-term planning & control.
Strategic: Long-term goals & direction.
Different Functions, Different Tools
Accounting & Finance: Managing money.
Marketing & Sales: Managing customers.
Human Resources: Managing people.
A Hierarchical View of Systems
Think of systems as a pyramid, with each layer supporting the one above it.
Strategic Level (Executive IS, Dashboards)
Managerial Level (Management IS, FAIS)
Operational Level (Transaction Processing Systems - TPS)
Interactive: Explore the IS Pyramid
Click each level of the pyramid to discover which information systems operate there.
Strategic Level
Executive IS & Dashboards Unstructured decisions — long-term planning

Managerial Level
Management IS & FAIS Semi-structured decisions — departmental control

Operational Level
Transaction Processing Systems (TPS) Structured, high-volume, routine data capture

Each level above relies on data flowing up from the level below.
🔑 The entire pyramid is built on the vast amount of data captured by Transaction Processing Systems (TPS) at the base.
This Unit's Key Players 🔍
We will explore three fundamental types of systems that form the backbone of modern organizations.
1. TPS
Transaction Processing Systems The workhorses that capture daily business data.
2. FAIS
Functional Area Information Systems The specialists that serve specific departments.
3. ERP
Enterprise Resource Planning The integrators that unite the entire organization.
1. Transaction Processing Systems (TPS) ⚡
Definition: Systems that monitor, collect, store, and process data generated from all routine business transactions.
Core Characteristics:
Handles high volume of data in real-time.
Must be reliable, fast, and accurate.
Forms the input for most other information systems.
Example: A supermarket's Point-of-Sale (POS) system scanning barcodes, calculating totals, and processing a payment via Fonepay.
Simulate: TPS in Action
Walk through each step of a Point-of-Sale transaction at a Kathmandu supermarket. Click the active step to proceed.

2. Functional Area IS (FAIS) 🎯
Definition: Systems designed to support the specific information needs of a single functional area or department.
Finance & Accounting IS
Financial planning
Accounts payable/receivable
Human Resources IS
Recruitment tracking
Payroll management
The Problem with FAIS: Information Silos
When each department has its own system, data becomes trapped.
Imagine the Sales department's system can't see the real-time stock levels in the Warehouse department's system. A customer might order an item that is out of stock.
Consequences of Silos:
Data is duplicated and often inconsistent.
Lack of a single, enterprise-wide view of the business.
Inefficient processes and poor decision-making.
Quiz: Spot the Silo
Each scenario below describes a real business situation. Decide whether it is an information silo consequence or not.
Scenario A: The Sales department confirms a large order for 200 units, but the Warehouse system (which Sales cannot access) shows only 50 in stock. The customer is disappointed.
Scenario B: When a sale is processed in the ERP system, the inventory count is automatically reduced and the Finance module reflects the updated revenue in real time.
Scenario C: HR records a promotion in their spreadsheet, but the Payroll system never receives the update. The employee is paid at the old salary next month.
3. The Solution: ERP Systems 🌐
Definition: Integrated software systems that manage all core business processes using a single, unified database.
ERP systems break down the information silos by creating a central hub.
🎯 The Goal: To create a single source of truth for the entire organization, from finance to manufacturing to HR.
FAIS vs. ERP at a Glance
FAIS (The Silos)
Department-specific
Multiple, separate databases
Can lead to data inconsistency
Difficult cross-departmental reporting
ERP (The Integrator)
Organization-wide
One central, unified database
Provides a single source of truth
Enables integrated business processes

Department-specific
Single unified database
Can create data silos
Cross-department integration
Payroll module only
SAP / Oracle suite
Multiple separate databases

Practical Application in Nepal
Example: A Local E-commerce Company (e.g., Daraz)
TPS in Action: When you place an order, the system processes the payment (via eSewa/Khalti), confirms the transaction, and sends an order confirmation. This is a classic TPS function.
FAIS Challenge: Initially, their marketing team might use a separate tool for email campaigns, while the warehouse uses a different system for inventory. The two systems don't talk to each other.
ERP Solution: A unified ERP system connects your order (Sales) to the warehouse (Inventory), notifies the delivery partner (Logistics), and updates the financial records (Accounting) all in real-time from a single platform.
Match the Nepal Scenario to the IS
Four real-world scenarios from Nepali businesses — click the correct IS type for each.
Hamro Superstore: A cashier scans an item at the counter; the system captures the sale, deducts stock, and triggers a payment via Khalti instantly.
Daraz Nepal: The HR team uses a dedicated software to track leave applications and process monthly payroll — separate from the sales and warehouse teams.
Nepal Airlines: A new system links ticketing, crew scheduling, fuel management, finance, and customer data into one central platform — all departments see live data.
NIC Asia Bank: Every ATM withdrawal in Kathmandu is logged, the customer balance is updated in real time, and an SMS alert is sent within seconds.
Unit 6 Intro: Key Takeaways
✅ Organizations use a variety of systems (TPS, FAIS, ERP) to support different functions and levels.
✅ Transaction Processing Systems (TPS) are the foundation, capturing the high volume of daily operational data.
✅ Functional Area IS (FAIS) are specialized but can create inefficient "information silos" that isolate data.
✅ Enterprise Resource Planning (ERP) systems aim to solve the silo problem by integrating all business functions into a single, unified system.
