Chapter 2: Strategic Use of Information Technology#

You have probably heard that technology can give a business an edge — but how exactly? This chapter explains the most powerful models that connect information technology (IT) to real competitive advantage. We will see why some companies succeed while others fall behind, and how to think like a strategist when investing in IT.

The Big Picture#

Strategy is about making choices that help an organization win — winning customers, market share, or efficiency. Information technology by itself is not a strategy; it is a tool. The magic happens when IT is carefully combined with the business model to strengthen the company’s position against rivals, make customers happier, and run operations more smoothly. This chapter gives you a set of ideas for that alignment, using well-known ideas from Michael Porter and today’s realities like the internet, global competition, and the bring‑your‑own‑device trend.

Porter’s Five Forces: Mapping Your Competitive Environment#

Before you can use IT to gain an edge, you need to understand the competitive pressures your organization faces. In 1979, Michael Porter introduced the five competitive forces model, which remains the starting point for any strategic analysis.

The five forces are:

1. Rivalry among existing competitors – how intensely companies in your industry fight for the same customers.
2. Threat of new entrants – how easy or hard it is for a new player to start competing with you.
3. Threat of substitute products or services – how easily customers can switch to a different kind of solution that fulfills the same need.
4. Bargaining power of buyers – how much pressure customers can put on prices, quality, or service.
5. Bargaining power of suppliers – how much control your suppliers have over the cost and availability of what you need.

Porter’s five forces: A model that looks at five competitive pressures in any industry; a strong force means more pressure on profits.

Each force can be strong or weak. The stronger the forces overall, the harder it is for any company in that industry to earn good profits. Strategy, then, is about positioning the firm where the forces are weakest — or changing the forces to your advantage. Information technology can influence every single one of these forces.

How the Internet Reshapes the Five Forces#

The internet did not create a new set of forces; it made the existing ones stronger or weaker. Let’s walk through the changes.

Rivalry often gets stronger. The internet makes it easy for customers to compare prices and features instantly. A local bookstore now competes not just with the shop across town but with global giants and digital marketplaces. Price transparency pushes margins down.

Entry barriers can go down — or up. On one hand, an online store can be launched with a laptop and a few hundred dollars, lowering barriers. On the other hand, companies that build massive data centres, proprietary algorithms, or network effects (like social media platforms) create huge digital barriers that are hard for newcomers to overcome. So the overall effect depends on the industry.

Entry barriers: Obstacles that make it difficult for a new competitor to enter an industry — high barriers protect incumbents.

Switching costs play a huge role here. A switching cost is any expense, hassle, or risk a customer faces when moving from one provider to another. IT can raise switching costs to lock customers in, or it can lower them to attract new ones.

Switching cost: The time, money, or effort a customer must spend to switch to a different supplier; high switching costs make customers less likely to leave.

For example, a business that has spent years customising its enterprise resource planning system will find it very expensive to switch to a different vendor. That vendor has a strong barrier against rivals. Meanwhile, cloud‑based software with easy data export purposely lowers switching costs, making the market more competitive.

Substitutes increase. The internet creates digital substitutes for physical products (e‑books instead of printed books, streaming instead of cable TV). IT can also help a company offer its own digital substitute before someone else does.

Buyers get more power. As we will explore shortly, the internet gives customers comparison tools, reviews, and instant price checks. This gives buyers more bargaining power, so companies must compete harder on value and service.

Suppliers can also gain power if a few tech providers control critical digital infrastructure. Think of the control of a handful of cloud platforms — businesses that depend on them have less power to negotiate.

Globalization and Increased Market Competition#

The internet removes geographic boundaries. A small artisan can sell handmade goods worldwide, but that same artisan now competes with thousands of other global sellers. Globalization — the integration of markets across countries — has been greatly increased by IT. Supply chains, customer support, and even professional services can be done from anywhere. For a business, this means both opportunity and threat. IT strategy must consider competitors that may come from anywhere in the world, often with lower costs or new business models.

Empowered Customers with Internet Comparison Tools#

Walk through any electronics store and you will see shoppers scanning barcodes with their phones to check online prices and read reviews. That is the reality of the empowered customer — a buyer who has easy access to information and can compare offers instantly. Comparison engines, social media, and user‑generated content give buyers near‑perfect information. The strategic response is not to fight this transparency but to use IT to deliver a better customer experience, personalized recommendations, or after‑sale service that a price‑only comparison cannot capture. Companies that ignore this shift find themselves in a race to the bottom on price.

📝 Section Recap: Porter’s five forces help you understand the competitive pressures in an industry, and the internet has changed those forces — making rivalry stronger, giving buyers more power, and changing entry barriers and switching costs. Smart IT strategy tries to weaken the forces working against you and strengthen the ones that protect your profits.

The Value Chain: Where IT Creates Value#

Understanding the external competitive environment is only half the story. You also need to look inside the organization to see where value is actually created. Porter’s value chain splits a company’s activities into a chain of steps that add value to the final product or service. By examining each step, you can spot where IT can cut costs, boost quality, or create something entirely new.

The value chain has two broad categories:

• Primary activities – those directly involved in creating and delivering the product.
• Support activities – those that enable the primary activities to run smoothly.

Value chain: A model that divides a company’s activities into primary and support categories, showing how each step adds value to the customer.

Primary Activities#

These typically include:

1. Inbound logistics – receiving, storing, and distributing inputs.
2. Operations – transforming inputs into the final product.
3. Outbound logistics – collecting, storing, and distributing the product to buyers.
4. Marketing and sales – persuading customers to purchase.
5. Service – maintaining and enhancing the product’s value after the sale.

Information technology can transform every one of these. A warehouse management system can greatly reduce the cost of inbound logistics. Robotics and real‑time monitoring can make operations faster and more consistent. A customer relationship management (CRM) system can personalize marketing and track service issues so that nothing gets missed.

Support Activities#

Support activities include:

• Firm infrastructure – general management, finance, legal, and planning.
• Human resource management – recruiting, training, and retaining people.
• Technology development – research and development, process improvement.
• Procurement – purchasing the resources the firm needs.

IT is obviously central to technology development, but it also makes procurement more efficient (e‑procurement systems), improves HR (online learning platforms, applicant tracking), and improves infrastructure (enterprise resource planning systems that give executives a single view of the business). The value chain reminds us that IT is not just for the factory floor or the website — it can improve the entire organization.

Generic Strategies: Cost Leadership, Differentiation, and Innovation#

The value chain analysis feeds directly into choosing a generic strategy. Porter identified three broad ways to outperform rivals:

• Cost leadership – becoming the lowest‑cost producer in the industry.
• Differentiation – offering something unique that customers value and are willing to pay a premium for.
• Focus – concentrating on a narrow market segment, either through low cost or differentiation within that segment.

Cost leadership: A strategy focused on minimizing costs across the value chain so the firm can offer lower prices or keep higher profits than competitors. Differentiation: A strategy of making a product or service seen as unique, allowing the company to charge a higher price.

Later thinkers added innovation as a separate strategic path — using technology to create entirely new products, services, or business models that make existing ones outdated. Think of how streaming services moved beyond DVD rentals.

IT can support any of these strategies. A cost leader might invest heavily in supply‑chain automation to drive down inventory costs. A differentiator might use data analytics to offer highly personalized recommendations that no competitor can match. An innovator might build a platform that connects buyers and sellers in a way that never existed before.

Operational Effectiveness and Customer Orientation#

It is easy to confuse operational effectiveness with strategy. Operational effectiveness means doing the same activities better than rivals — faster, with fewer errors, or at a lower cost. IT is great at improving operational effectiveness: robotic process automation, real‑time dashboards, and predictive maintenance all help. But operational effectiveness alone is not strategy, because competitors can copy it. True strategy means choosing a unique position that is hard to copy.

Operational effectiveness: Performing similar activities better than competitors; it is necessary but not enough for long‑term advantage.

Closely related is customer orientation — putting the customer’s needs at the center of every decision. IT enables customer orientation through tools like sentiment analysis (understanding how people feel from their online posts), 360‑degree customer views, and self‑service portals. When a bank lets you deposit a check by taking a photo, that is IT directly improving your experience. The goal is to make the customer feel understood and valued, which builds loyalty that a price‑comparison app can’t easily break.

📝 Section Recap: The value chain reveals where value is added inside the firm, and IT can improve both primary and support activities. Whether you pursue cost leadership, differentiation, or innovation, aligning technology with the value chain turns IT from a cost center into a competitive weapon.

Aligning IT with Business Goals#

All the models in the world are useless if the technology department and the business side of the company are not talking to each other. Business‑IT alignment means that every IT investment directly supports a clear business objective, and business leaders understand enough about technology to make smart trade‑offs.

Business‑IT alignment: The degree to which the IT strategy and the overall business strategy are aligned and support each other.

Misalignment shows up in common signs: the IT team introduces a new system that nobody asked for; the marketing department buys a cloud tool without telling IT, creating a security problem; executives approve a huge ERP project without understanding how it will actually improve customer retention. Alignment requires shared language, joint planning, and decision‑making processes where business and IT leaders make decisions together.

When alignment is strong, IT becomes a strategic partner. The chief information officer (CIO) sits at the table when business strategy is discussed, not just when the server crashes. IT projects are prioritized based on their contribution to competitive advantage, not just on technical appeal. This is how technology truly moves the business forward.

📝 Section Recap: Business‑IT alignment ensures that technology decisions are driven by strategic goals, not by new tools. It turns the IT function into a real partner in shaping the company’s future.

Navigating Today’s Digital Challenges: Information Overload and BYOD#

Even the best strategy can be thrown off track by two modern problems: the huge amount of data and the mixing of personal and company devices.

Information Overload from Data Volume Growth#

We generate a huge amount of data every day — transaction logs, social media streams, sensor readings, emails, and more. This information overload can freeze decision‑making. Managers get overwhelmed by dashboards and reports, unable to tell what’s important from what’s not.

Information overload: A state in which the amount of available data is more than a person’s or organization’s ability to handle it well, leading to worse decisions.

Strategically, the answer is not to collect less data but to invest in business intelligence and analytics that bring out the right insights at the right time. A retailer might track millions of customer interactions, but the strategic value comes from a system that predicts which customers are about to leave and automatically sends a special offer to keep them. IT strategy must include a plan for turning raw data into useful knowledge, otherwise the data becomes a burden.

BYOD Policies and Security Challenges#

Bring Your Own Device (BYOD) refers to employees using their personal smartphones, tablets, and laptops for work. It makes employees happier and can reduce hardware costs, but it also creates many security risks. A lost phone with no protection, a personal app infected with malware, or a family member accidentally accessing sensitive files — all can lead to data leaks.

BYOD (Bring Your Own Device): A policy that allows employees to use their personal devices to access company networks and data, mixing work and personal life.

From a strategic standpoint, BYOD is not just an IT security problem. It affects the company’s ability to protect its ideas and inventions, follow privacy laws, and maintain customer trust. A well‑designed BYOD policy, supported by mobile device management software and clear rules about what can and cannot be stored on personal devices, turns a risk into a manageable part of the digital workplace. Ignoring BYOD is not an option when employees are already checking work email on their own phones — the strategy must handle it safely.

📝 Section Recap: Information overload requires that IT strategy includes smart analytics to turn data into decisions, not just noise. BYOD is a reality that, with the right policies, can boost productivity without hurting security.

Summary#

We started with the big question: how can a business use technology to truly get ahead? The answer lies in understanding the competitive forces shaping your industry, looking inside your own value chain to see where IT can add the most value, and making sure every tech decision is locked in step with your business goals. Porter’s five forces show you the external pressures; the value chain reveals your internal levers; and alignment keeps the whole machine pointed in the same direction. Along the way, we saw how the internet has given customers more power, lowered some barriers while raising others, and forced companies to compete globally. Finally, we acknowledged that modern challenges like data overload and BYOD are not distractions — they are strategic issues that must be dealt with directly. Treat IT as a strategic asset, not just a utility, and you will be thinking like a true business strategist.
