1 What is the Internet of Things (IoT)? ▼
The Internet of Things (IoT) refers to the billions of devices connected to the Internet that are constantly collecting and storing data. Today, practically any device can be connected — from factory sensors to smart home gadgets.
Campus Example
Think of your campus ID card. Every time you tap it to get into a building, buy a coffee, or do laundry, that data is collected and stored — that's IoT in action, right in your pocket.
2 What is ERP and why does it matter? ▼
Enterprise Resource Planning (ERP) is a computer system that integrates application programs in accounting, sales, manufacturing, and other functions in a firm. The integration is accomplished through a single shared database.

From a manager's perspective, ERP is a comprehensive software approach to support decisions while planning and controlling the business.
Campus Example
Imagine if your university's registration system, financial aid office, dining plan, housing, and transcript system all ran off one connected database. Change your address once, and every office sees it instantly. That's the ERP idea!
3 Why is a single shared database such a big deal? ▼
ERP works from a single database where transactions are processed in real time — as soon as a transaction is entered, the effect is known by all users. This eliminates reposting of data (which reduces errors) and ensures everyone sees the same, up-to-the-minute information.
Campus Example
Without a shared system: you drop a class but financial aid doesn't find out for two weeks, and the bookstore still charges you for the textbook rental. With a shared database: you drop the class, and every connected office updates instantly.
4 What are the 4 software imperatives for ERP quality? ▼
Four aspects determine the quality of an ERP system:

1. Multifunctional in scope — covers many business areas
2. Integrated — all parts connect and share data
3. Modular in structure — built in pieces you can mix and match
4. Facilitates planning & control — helps you plan and manage operations

Key fact: An ERP system can be built with software modules from different vendors. You don't have to buy everything from one company!
Interview Tip
If asked about ERP system design, mention that modern ERP is modular — companies can adopt the modules they need without buying a massive all-or-nothing package.
5 What are the 4 typical ERP module categories? ▼
1. Finance — automatic capture of accounting transactions
2. Manufacturing & Logistics — the largest and most complex module
3. Sales & Marketing — customer management, forecasting
4. Human Resources — manage, schedule, pay, hire, and train people
Campus Example
Think of a campus dining operation: Finance tracks meal plan revenue, Manufacturing & Logistics manages food prep and supply ordering, Sales & Marketing handles the meal plan sign-ups, and HR schedules student workers.
6 Which ERP module is the largest and most complex? ▼
Manufacturing and Logistics — it covers production planning, inventory, scheduling, distribution, and vendor management. It's the workhorse of ERP because it coordinates the most moving parts.
7 Transaction processing vs. decision support — what's the difference? ▼
Transaction processing = the posting and tracking of activities that document the business. Efficiently handling transactions as goods move through each step is the primary goal of an ERP system.

Decision support = the system helps users make intelligent judgments about how to run the business. This is a second objective — people make decisions, and the system supports better decision-making.
Campus Example
Transaction processing: Every time you swipe your meal plan at the dining hall, the system records it — that's a transaction.
Decision support: The dining director reviews those swipe trends and realizes lunch traffic drops 40% on Fridays. They use that data to decide to reduce Friday staffing. Same system, two different purposes!
8 What is a data warehouse? ▼
A data warehouse is a special program designed to automatically archive and process data for uses that are outside the basic ERP system applications. Think of it as the "deep storage" that lets you run custom reports and analysis beyond what ERP normally provides.
Campus Example
Your university's ERP handles daily class registration. But when the provost wants to analyze 5-year enrollment trends by major, that complex analysis is pulled from a data warehouse, not the live registration system.
9 Who are the major ERP vendors? ▼
SAP is the world's largest ERP vendor, dominant among large enterprises.

Microsoft Dynamics is Microsoft's ERP offering, more oriented toward use in smaller businesses.

Key point: ERP systems don't have to be purchased entirely from a single vendor — you can mix modules from different companies.
Interview Tip
Knowing the difference between SAP (enterprise-scale) and Microsoft Dynamics (mid-market) shows you understand that ERP isn't one-size-fits-all — solutions should be matched to company size and needs.
10 What are SAP's 4 supply chain functions? ▼
SAP divides its supply chain software into four main functions:

1. Supply Chain Planning — demand & supply matching
2. Supply Chain Execution — materials management, collaborative manufacturing, fulfillment
3. Supply Chain Collaboration — VMI, inventory hubs, enterprise portal
4. Supply Chain Coordination — event monitoring, performance KPIs
11 What are VMI and collaborative manufacturing? ▼
Vendor Managed Inventory (VMI) enables vendor-driven inventory replenishment — the supplier monitors your stock and refills it automatically.

Collaborative manufacturing is the sharing of information with partners to coordinate production, enabling everyone to work together to increase visibility and responsiveness.
Real-World Example
Think about how Coca-Cola restocks a campus vending machine. With VMI, the machine sends data to Coca-Cola's system. When stock is low, a truck is dispatched automatically — the university never has to place an order.
12 What 3 functions make up the internal supply chain? ▼
Three major functional areas make up the internal supply chain of a manufacturing enterprise:

1. Purchasing
2. Manufacturing
3. Sales & Distribution

Tight cooperation between these three is required for effective manufacturing planning and control. The ERP system provides performance metrics to evaluate how well they're aligned.
13 Is ERP right for every company? ▼
No! ERP systems provide many benefits, but those benefits can only outweigh the high cost of implementation and operation in larger firms. Simpler management software systems may be more appropriate for smaller companies.

Also, companies can suffer from information overload if the system isn't configured properly or if people aren't trained to use it.
Interview Tip
Saying "ERP is always the answer" is a red flag. Smart consultants know that the right solution depends on company size, complexity, and budget. A small bakery doesn't need SAP!
