Session 01: Introduction to Strategy

Why Do Firms Need Strategy At All?

Before we can argue about how strategy is made, sit with a harder question first: why does a firm need one? Every company already makes thousands of decisions a year — hiring, pricing, sourcing, marketing. Why isn't "make each decision well, using good judgment" enough? What is the extra thing that "strategy" is supposed to add?

Harvard's Introduction to Strategy core reading (Casadesus-Masanell, HBP 8097) gives the tightest version of an answer: strategy is "the integrated set of choices that positions the business in its industry so as to generate superior financial returns over the long run." It is a firm's answer to exactly two questions — where should we compete, and how should we compete? Good decisions made one at a time, in isolation, do not automatically add up to a coherent answer to either question. A firm can hire brilliantly, price cleverly, and market aggressively, and still have no strategy — because none of those choices reinforce one another or defend a distinctive position against competitors trying to take it away.

Rothaermel's Strategic Management (Ch. 1) frames the same idea through the AFI framework — strategy as an ongoing cycle of Analysis, Formulation, and Implementation aimed at competitive advantage: the ability to create more economic value than rivals and to keep a larger share of the value created than they do. That last clause matters. A firm can create enormous value for the world (Tesla, by most accounts, has meaningfully accelerated the shift away from internal-combustion vehicles) and still fail to capture enough of that value to survive as a business. Strategy is about both.

So why do firms need it? Three reasons converge across the readings for this session:

Because good decisions can still add up to a bad position. A firm that tries to serve every customer, match every competitor's feature, and enter every attractive-looking market ends up "stuck in the middle" — Porter's term for a firm with no distinctive position and no defensible cost advantage. Every individual choice may look reasonable; the whole is incoherent.
Because success creates its own blind spots. Jan Rivkin's internal-barriers framework (cited in the Core Reading) names four ways organizations fail to respond to a threat even when smart people are inside them: Perception ("I don't see the threat"), Motivation ("I see it but don't want to respond"), Inspiration ("I want to respond but don't see how"), and Coordination ("I see how, but can't get the organization to move"). Blockbuster saw Netflix and chose not to cannibalize its own stores — a motivation failure. We will ask, in the Tesla story below, which of these four failures nearly killed Tesla in 2007–2009, and which one is the live risk for legacy automakers watching BYD today.
Because industries themselves are not equally profitable — on average, 5–15% of the variance in firm profitability is explained by which industry a firm is even in. Choosing where to compete (the first of the two fundamental questions) is not a detail; for many firms it explains more of the outcome than any operational excellence they layer on top.

Keep those three reasons in mind. Tesla's 23-year history is a case study in almost losing on all three — and finding, more by learning than by grand design, a way to survive.

The Tesla Story: 2003–2026

Five chapters, one company, two competing explanations for how it got here. After each chapter, click to analyze it through Porter's design lens and Mintzberg's crafting lens — then decide for yourself which one is doing more explanatory work.

Tesla Market Capitalization, 2018–2026 ($ Billions)

A single number that swung 32x peak-to-trough-to-peak in eight years. Ask yourself: does a chart this volatile look like it was following a deliberate plan?

Sources: Serafeim & Migdal, Elon Musk at Tesla, HBS 9-123-044, Exhibit 14a (2018, 2021, 2022 figures); companiesmarketcap.com / tradingeconomics.com (August 2026 figure).

Chapter 1 (2003–2009): A Garage Bet Nobody Wanted to Fund

If electric cars were obviously a good idea, why had every serious attempt — GM's EV1, dozens of 1970s conversions — already failed?

Tesla Motors was founded in 2003 by Martin Eberhard and Marc Tarpenning, who estimated they needed $25 million to reach break-even and initially priced their planned Roadster around $49,000 in production cost. In 2004 Elon Musk — fresh off $165 million from the PayPal sale and already funding SpaceX — put in $6.3 million of the $6.5 million first round and became chairman.¹ The founders had rejected retrofitting existing chassis; instead they built a purpose-designed EV from scratch and sold it direct to consumers, skipping the franchise-dealer network every other automaker depended on.

It nearly ended the company. By 2007 Tesla had spent $100 million and had not shipped a single production car; per-unit costs had more than doubled from the original estimate. Musk fired Eberhard, took over as CEO himself (while still running SpaceX and chairing SolarCity), and personally wired in another $20 million. By the end of 2009 Tesla had less than $500,000 in operating cash — while Musk was going through a divorce and had just watched a SpaceX rocket fail on launch. He put in the rest of his money anyway and raised $40 million more from his brother and other investors.²

In an August 2006 blog post, Musk had already published what he called "The Secret Tesla Motors Master Plan": "(1) Build sports car; (2) Use that money to build an affordable car; (3) Use that money to build an even more affordable car; (4) While doing above, also provide zero emission electric power generation options."³ That four-step plan — published while the company was years from proving any of it could work — is either the clearest evidence of deliberate strategy in this whole case, or a piece of aspirational marketing copy that the actual company spent the next fifteen years scrambling to catch up to. Judge for yourself once you have read the whole story.

Porter's Lens:

The founders made two real trade-offs from day one: build the platform from scratch rather than convert an existing chassis (sacrificing speed-to-market for a coherent activity system later), and sell direct rather than through dealers (sacrificing distribution reach for control and margin). Both choices were costly and reversible-only-with-difficulty — exactly Porter's test for a genuine strategic position rather than an operational tweak.

Mintzberg's Lens:

The "Master Plan" reads as an umbrella strategy in Mintzberg's sense: leadership set a broad, deliberate direction ("sports car → affordable car → mass car") and left the specifics — which battery chemistry, which factory, which body style — to be learned in the field. The 2007 crisis and CEO change were pure emergence: nobody planned to fire the founding CEO after burning $100M with zero cars shipped. The realized strategy, per Mintzberg, is always "a blend of deliberate and emergent" — this chapter is where you can see the blend most starkly.

Chapter 2 (2009–2014): The Nummi Gamble and the Model S

In 2010, Tesla had sold 765 cars total. Nissan alone sold 6,665 EVs that same year. Why did anyone bet on the smallest player in the industry?

In 2010 Musk learned Toyota was shopping the shuttered Nummi factory (5.5 million sq ft, once producing 450,000 cars a year for Toyota and GM) at a $1 billion asking price. He toured it in disguise as an autoworker and offered $42 million — Toyota accepted a month later and also invested $50 million for 2.5% of Tesla's equity.⁴ That same year Tesla IPO'd, raising $226 million.

The Model S, launched in 2012, was where "different set of activities" stopped being a slogan: no exhaust system freed up cabin space for a third row of seats; a flat under-floor battery pack lowered the center of gravity; a 17-inch touchscreen and over-the-air software updates meant many repairs never required a service visit at all. Tesla sold the car through mall stores modeled on the Apple Store rather than dealerships, with commission-free staff whose job was explicitly "answering the many questions [customers] have about electric vehicles," not closing a sale.⁵ Consumer Reports gave the Model S a 99/100, the highest score the magazine had ever awarded a car.

It was also nearly a repeat of the Roadster crisis: 2012 deliveries (~3,000) missed the 5,000-unit target, and by 2015 Tesla was still losing $4,000 on every vehicle it sold, even as the Model S remained the only EV on the market that could drive more than 100 miles on a charge.

Porter's Lens:

This is textbook fit. No-exhaust design reinforces cabin space, which reinforces the "not just a car, a computer on wheels" positioning, which reinforces the mall-store, no-commission retail model that's built to educate rather than push a sale. Each choice makes the others more valuable — second-order fit, in Porter's language — and that combination is what a Continental-Lite-style imitator (retrofit an EV into a dealer network) could not easily replicate.

Mintzberg's Lens:

The Nummi purchase was opportunistic pattern-recognition, not five-year planning — Musk toured the factory undercover because the opportunity appeared and had to be seized in weeks, not because it was in anyone's roadmap. Mintzberg would call this a craftsman "sensing" an opening in the clay: the plan didn't predict Nummi would become available at a fire-sale price; leadership recognized the pattern and moved.

Chapter 3 (2015–2019): Fires, Fraud Charges, and a $55.8 Billion Bet on One Man

In January 2018, Tesla's board tied Musk's entire compensation to hitting a market cap of $650 billion — when the company was worth $52 billion. Was that visionary or reckless?

This chapter reads like a corporate-governance case, not a product one. In November 2016, Tesla acquired SolarCity — Musk's cousins' solar company, which he chaired and part-owned — for $2.6 billion, while carrying $3.4 billion in debt and spending $500 million a quarter. An investor shorting both companies called it a "shameful example of corporate governance at its worst." ⁶ In January 2018 Tesla's board approved a pay package giving Musk up to $55.8 billion across 12 tranches, each requiring a $50 billion jump in market cap plus revenue and EBITDA milestones — proxy advisors ISS and Glass Lewis both recommended shareholders vote it down.

Then, on August 7, 2018, Musk tweeted: "Am considering taking Tesla private at $420. Funding secured." Shares spiked 11%, short-sellers lost $1.3 billion in a day — and the funding was not, in fact, secured. The SEC charged Musk with securities fraud; he and Tesla each paid $20 million in penalties, and Musk was forced to step down as chairman for at least three years.⁷ Meanwhile Model X software and hardware problems (falcon-wing door recalls, two fatal Autopilot crashes in 2016 and 2018) piled up, and Tesla closed 2018 at nearly 250,000 deliveries — more than double 2017, but still less than half of the 500,000-unit target Musk himself had set in 2016.

Porter's Lens:

SolarCity is the era's clearest "fit" failure: Porter would ask whether the acquired activities reinforce Tesla's existing system. Analysts said no — solar-roof installation shares almost nothing with EV manufacturing, retail, or software, and the deal's logic rested on Musk's personal ties to both firms rather than on economic complementarity. The 2018 pay package, by contrast, is a genuine (if extreme) trade-off: Musk receives no other compensation in exchange for total alignment with one long-horizon bet — a real, costly commitment, which is Porter's test for whether a choice is strategic or just cheap talk.

Mintzberg's Lens:

Nobody "planned" a securities-fraud charge. This is the emergent, learning side of strategy at its most costly: the realized outcome (a chastened, more governed Tesla with an independent chairman and new board oversight of Musk's tweets) was imposed by regulators and the market, not designed in advance. Mintzberg's warning that "strategies can form as well as be formulated" cuts both ways — sometimes what forms is discipline you didn't choose.

Chapter 4 (2020–2022): Richest Man in the World, Then First to Lose $200 Billion

Tesla's market cap went from $52B to $700B to over $1 trillion to a $1.24 trillion peak to $389B — all in five years. What kind of "strategy" produces that chart?

The 2019 Model 3 ramp finally delivered scale: Tesla hit 500,000 deliveries in 2020, and by January 2021 its market cap reached $700 billion, making Musk briefly the richest person alive. In October 2021 a 100,000-vehicle Hertz order pushed the market cap past $1 trillion; by 2022 it peaked near $1.24 trillion — more valuable than Toyota, Volkswagen, Mercedes-Benz, and GM combined.⁸

Then, in April 2022, Musk launched a bid for Twitter, closing the $44 billion acquisition that October, firing the CEO, and cutting roughly half of Twitter's 7,500 employees within weeks. As the Fed raised interest rates through 2022, high-growth stock valuations fell across the board and Tesla's own stock dropped more than 60% — while Twitter reportedly lost $4 million a day. By December 2022 Tesla's market cap had fallen to $389 billion, and Musk became, per Bloomberg, the first person ever to lose more than $200 billion in net worth. Tesla's third-largest individual shareholder tweeted publicly that "Tesla has no working CEO."

Porter's Lens:

Porter's framework says almost nothing about a stock-market rollercoaster like this — and that's the point worth noticing. Porter analyzes a firm's position and activity system, which changed relatively little in these three years; the $850B swing came almost entirely from shifting investor beliefs about the future (autonomy, macro rates, Musk's attention). This is a useful boundary condition: Porter's tools explain durable competitive advantage, not short-run valuation.

Mintzberg's Lens:

Buying Twitter was Musk's individual, deliberate strategy for Musk — but an emergent, unrequested strategy for Tesla, whose shareholders never voted on it and whose CEO's attention it visibly consumed. This is Mintzberg's point about "who is the strategist anyway?" taken to its limit: when a founder-CEO's personal ventures and the company's realized strategy become entangled, whose intentions are we even reading?

Chapter 5 (2023–2026, right now): "If You Think We Are a Car Company, You Are Totally Wrong"

BYD out-produced Tesla in Q4 2023. Musk's response was not to cut prices harder — it was to redefine what business Tesla is in. Is that strategy, or is it spin from a company that is losing a price war it cannot win?

By 2023, BYD had captured 35% of China's domestic auto market and sold 1.58 million EVs (3 million total NEVs including plug-in hybrids) to Tesla's 1.8 million — and out-produced Tesla outright in Q4 2023. BYD's advantage is structural, not cosmetic: it owns cobalt mines, produces its own battery cathodes, and even operates its own roll-on/roll-off ships for export — a vertically integrated cost position Tesla cannot easily match. Xiaomi, a smartphone maker, launched an EV sedan priced at $30,000–$42,000 that critics compared directly to a $140,000 Porsche Taycan.⁹ Tesla's own gross margin fell for six straight quarters, from 29.1% in Q1 2022 to roughly 17% by early 2024, and in 2024 the company cut more than 10% of its global workforce.

Musk's answer, repeated in 2024 investor calls: "[Tesla] should be thought of as an AI or robotics company... The way to think of Tesla is almost entirely in terms of solving autonomy and being able to turn on that autonomy for a gigantic fleet."¹⁰ In November 2025, Tesla shareholders approved a new Musk pay package reportedly worth up to $1 trillion if the company hits extraordinary market-cap and operational milestones — passing with over 75% approval, an even larger bet on one person than the 2018 package. And the numbers backing the pivot are real: in Q2 2026 alone, Tesla delivered a record 480,126 vehicles (up 25% year-over-year), Cybercab production began at Gigafactory Texas, Robotaxi service went live (unsupervised) in seven U.S. metros including Miami, Orlando and Tampa, and capital spending on the autonomy bet more than tripled to over $25 billion for the year — pushing free cash flow to −$1.1 billion in the quarter.¹¹ As of August 2026, Tesla's market cap sits around $1.33 trillion — roughly back to its 2022 peak, on a story that has almost nothing to do with how many cars it sells.

The INSEAD case that tracks this era ends with the question we will ask you to answer, live, in the CSO simulation below: "Taken together, will Tesla remain the disruptor, or will it ultimately be disrupted?"

Porter's Lens:

If real, this is a repositioning — a bet that the "wedge" between willingness-to-pay and cost lives in autonomy software, not sheet metal. But Porter would immediately ask about trade-offs: can Tesla simultaneously fight a margin war on vehicles and fund a capital-intensive robotaxi build-out without becoming "stuck in the middle" on both? Negative free cash flow while capex triples is the visible cost of that trade-off being made in real time.

Mintzberg's Lens:

This looks like Miller & Friesen's "quantum" strategic revolution, which Mintzberg cites directly: long periods of stability (a decade of "we are an EV company") punctuated by a short, disruptive reorientation once the old strategy falls out of sync with its environment (BYD's rise). Notice the umbrella: Musk deliberately set the destination ("solving autonomy... for a gigantic fleet"), but the city-by-city Robotaxi rollout — Austin, then Miami, Orlando, Tampa, with more metros pending permitting and first-responder training — is being learned, one regulatory environment at a time. Deliberate top, emergent underneath.

The Two Lenses, Formally

Now that you have seen both lenses applied five times to one company, here is what each actually claims — in the authors' own words.

1. The "Design" Lens: Michael Porter (1996)

Porter's "What Is Strategy?" (HBR, Nov–Dec 1996) opens by attacking a confusion: "The root of the problem is the failure to distinguish between operational effectiveness and strategy." Operational effectiveness (OE) means "performing similar activities better than rivals"; strategy means "performing different activities from rivals' or performing similar activities in different ways." Gigacasting that drops Tesla's battery cost to $142/kWh versus an industry average of $186 is OE — valuable, but copyable, and indeed BYD is closing that gap with its own vertically integrated cost base.

Strategy, for Porter, requires three things in sequence: a unique position (built from needs, variety, or access — see the next section), trade-offs ("the essence of strategy is choosing what not to do"), and fit across a whole system of activities, so that "competitors get little benefit from imitation unless they successfully match the whole system."

Key Concepts:

Operational Effectiveness vs. Strategy
Positioning: Needs, Variety, or Access
Trade-offs — "choosing what not to do"
Fit (1st, 2nd, 3rd order) across activities

2. The "Craft" Lens: Henry Mintzberg (1987)

Mintzberg's "Crafting Strategy" (HBR, Jul–Aug 1987) opens with a potter at her wheel, not a general in a war room: "Formulation and implementation merge into a fluid process of learning through which creative strategies evolve." His central move is a distinction most managers blur: a plan is "intended strategy"; the consistent pattern a firm's actions actually trace over time is "realized strategy" — and "just as a plan need not produce a pattern... so too a pattern need not result from a plan."

His most quoted line is the reconciliation, not the provocation: "[S]trategy formation walks on two feet, one deliberate, the other emergent." Honda's small-motorcycle success in the U.S. is his classic illustration — the intended strategy (sell big bikes) failed; the realized strategy (dominate with the Super Cub) emerged from salespeople's on-the-ground learning and was only later legitimized by headquarters as "the plan all along."

Key Concepts:

Intended vs. Realized Strategy
Deliberate vs. Emergent components
Umbrella Strategy (deliberate direction, emergent detail)
Miller & Friesen's "Quantum" Strategic Revolution

Neither author thinks the other is wrong about everything. Mintzberg himself concedes strategy needs "control just as it requires responsiveness"; Porter's own positioning examples (Ikea, Vanguard) took years of iteration to reach the "clear" position he later describes. The live debate is about emphasis — how much of a firm's success to attribute to foresight versus to learning.

Porter's Strategic Positions: Examples

Porter identified three distinct sources from which a strategic position can emerge: needs, variety, or access. Let's see them in action — including Tesla's own.

1. Needs-Based Positioning

Serving most or all needs of a particular customer group.

🇮🇳 Urban Company

Need: Reliable, quality home/personal care for busy urbanites.

Solution: Vetted partners via platform.

Position: Trusted one-stop-shop.

🌍 Tesla (2012 Model S launch)

Need: Affluent, tech-forward buyers who wanted a luxury sedan and a climate-conscious, software-first ownership experience — a need no incumbent luxury brand was built to serve.

Position: "It's a computer on wheels," per an early owner quoted in the case — a full ownership experience, not just a powertrain swap.

2. Variety-Based Positioning

Producing a subset of an industry's products or services.

🇮🇳 Rebel Foods

Variety: >45 distinct food brands (Faasos, etc.) from cloud kitchens.

Solution: Tech platform manages multiple brands efficiently.

Position: Go-to for any food craving (delivered).

🌍 Zara

Variety: Constantly rotating "fast fashion" trends.

Solution: Agile supply chain delivers new styles weekly.

Position: Affordable, endless fashion variety.

3. Access-Based Positioning

Segmenting customers accessible in different ways.

🇮🇳 Reliance Jio

Access Barrier: Lack of affordable internet in rural/low-income India.

Solution: Free 4G trials, cheap phone, nationwide network.

Position: Enabler of digital inclusion.

🌍 Tesla Supercharger Network

Access Barrier: Long-distance EV travel was blocked by "too few and too unreliable" public chargers, per the INSEAD case.

Solution: Tesla built and owned 6,000+ proprietary Supercharger stations before opening the network to rival brands in 2023.

Position: Made long-distance EV ownership possible years before any competitor could match it.

How to Differentiate the Positions

The three positions differ primarily in their starting point or focus, dictating how activities are structured.

Characteristic	Needs-Based	Variety-Based	Access-Based
Primary Focus	Specific customer group	Subset of products/services	Unique customer accessibility
Segmentation	Customer needs/profile	Product/service itself	Geography, scale, channel
Target Market	Narrow segment, all needs	Wide market, specific offering	Hard-to-reach customers
Starting Question	"Who is our target customer?"	"What product can we excel at?"	"How can we reach them uniquely?"

Porter's Concept of Fit: Reinforcing Activities

"Fit" is how a company's activities interact and reinforce one another, making strategy sustainable and hard to copy. Porter identifies three levels.

1. First-Order Fit (Simple Consistency)

Basic alignment: each activity is consistent with the overall strategy.

🌍 McDonald's

Strategy: Quick, affordable, consistent fast food.

Consistency: Standardized menu, store layout, drive-thru, operating procedures all reinforce speed and low cost.

🇮🇳 Nirma

Strategy: Low-cost, mass-market detergent.

Consistency: Cost focus in manufacturing, rural distribution, low-price ads, simple packaging all align with the low-cost position.

2. Second-Order Fit (Reinforcing Activities)

Activities actively reinforce one another; the whole > sum of parts.

🌍 Southwest Airlines

Strategy: Low-cost, convenient, point-to-point travel.

Reinforcement: Single plane type simplifies maintenance/training → quick turnarounds → high utilization → low fares.

🇮🇳 Titan Company (Early Days)

Strategy: High-quality, aspirational watch brand.

Reinforcement: Stylish design + exclusive 'World of Titan' retail experience + quality after-sales service = reinforced premium brand image.

3. Third-Order Fit (Optimization of Effort)

Coordination across activities eliminates redundancy and waste.

🌍 IKEA

Strategy: Stylish, affordable, self-assembly furniture.

Optimization: Modular design → flat-packing → efficient logistics + customer self-service/transport/assembly = optimized low-cost system.

🌍 Tesla Gigacasting

Strategy: Radically simplify vehicle manufacturing.

Optimization: Single-piece die-cast front and rear underbody sections (replacing dozens of welded parts) + in-house 4680 battery cells + software-first OS eliminate entire categories of assembly steps, cutting cost per car well below the industry's own reported average.

Comparison of Fit Types

Feature	First-Order Fit	Second-Order Fit	Third-Order Fit
Definition	Each activity consistent	Activities reinforce each other	Activities optimized across system
Purpose	Alignment	Synergy (Whole > Sum)	Max efficiency, eliminate waste
Analogy	Puzzle pieces fit edges	Intertwined chain links	Optimized, interlocked puzzle
Imitability	Easy (copy activity)	Hard (copy system)	Extremely difficult (copy coordination)

Decision Workshop: Real Choices, Real Stakes

Two quick decisions grounded in Tesla's actual history, then a full scenario: you are Tesla's Chief Strategy Officer, in 2026, right now.

Decision 1: The 2006 Master Plan

It's 2006. Tesla has no factory, no revenue, and one prototype. Eberhard and Tarpenning ask Musk: should Tesla launch with a $49,000 mass-market car to reach scale fast, or an $80,000+ low-volume sports car to prove the technology first?

Decision 2: Dealers or Direct?

It's 2008. Every automaker on Earth sells through independently owned franchise dealers, who provide instant nationwide reach, local service, and financing relationships Tesla does not have. Tesla is nearly out of cash. Do you use dealers to scale faster?

Quick Decision: The Amenity Trade-off

Your budget airline is known for rock-bottom fares. A consultant suggests adding free checked bags and snacks like the major full-service carriers, to attract more customers. According to Porter, should you do it?

Scenario: You Are Tesla's Chief Strategy Officer — 2026

This scenario is built directly from the discussion questions in Tesla (Act 2): Disruptor or Disrupted? The numbers are real. The decision is yours.
