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)

Each level above relies on data flowing up from the level below.

🎬 Watch: Types of Information Systems

The Foundation: TPS

🔑 The entire pyramid is built on the vast amount of data captured by Transaction Processing Systems (TPS) at the base.

🧮 Worked Example: One Sale, Four Systems

Illustrative: a pharmacy chain with 12 branches in Nepal.

LevelSystemWhat it does with the sale
OperationalTPSRecords "1 × paracetamol strip, Lalitpur branch, 10:42 am".
ManagementMISWeekly report: paracetamol sales by branch vs. last week.
ManagementDSS"What if we move 200 strips from Bhaktapur to Lalitpur before flu season?"
StrategicEISDashboard: total revenue trend, top 5 branches, stock-out alerts.

Same data, summarised more at each level. Without the TPS, nothing above it works.

🧪 Quick Activity: Which System Answers This?

TPS, MIS, DSS or EIS?

  1. "Record that a student paid this semester's fee." → TPS
  2. "Show me the monthly report of fee collection by faculty." → MIS
  3. "If we raise fees 5%, how many students might we lose?" → DSS
  4. "One screen for the principal: enrolment, revenue and results trends." → EIS

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.

🎬 Watch: Why Data Silos Hurt

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

⚖️ ERP Isn't Free Magic: Limitations

  • Cost: licences, consultants, training and hardware/cloud fees.
  • Time: implementations often take months to years.
  • Process change: staff must adopt the system's standard way of working.
  • Risk: a failed go-live can stop shipping, billing or payroll.
  • In Nepal: few local implementation experts, and international vendors may not fit local tax and reporting rules out of the box.

👟 Real Case: When Integration Goes Wrong

Around 2000, Nike rolled out new demand-planning software from vendor i2, linked to its other enterprise systems.

  • The new system produced faulty forecasts: too many of some shoes, too few of popular models.
  • In February 2001, Nike publicly blamed the problems for a shortfall in quarterly sales, and its share price fell sharply.
  • Nike and i2 blamed each other: rushed rollout vs. poor use of the software.
  • Nike kept going, fixed the rollout, and later completed its wider integration programme.
Lesson: integrated systems spread one bad input to every department, fast.

🎬 Watch: ERP in Under 2 Minutes

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 (illustrative scenario): 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.

☁️ Preview: Where Do These Systems Run?

Many TPS, FAIS and ERP systems are now rented over the internet. Three models (full detail in Unit 6.6):

IaaS
Rent servers and storage; you install and run everything else.
e.g. DigitalOcean Droplets
PaaS
Rent a ready platform; you just deploy your own code.
e.g. Microsoft Azure App Service
SaaS
Use finished software in a browser.
e.g. a cloud payroll or accounting app

Moving left → right: less control, less work for your IT team.

💬 Discuss: Your Organisation's Systems

  • Think of a business you know (a shop, a bank, your college). Which TPS does it use?
  • Are its departments in silos? How can you tell?
  • Would ERP be worth the cost for it? Why or why not?

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.
