Portfolio logic
Capital can move toward attractive opportunities. But owning a portfolio does not automatically create an operating advantage: investors can often diversify for themselves. What does the parent contribute?
Session 10FormulationPGPM 2026–27 · 90 minutes
Alliances, Mergers & Acquisitions
Why own a company when you only need a capability?
Amazon builds, licenses, partners and acquires. Use the revised readings to compare those routes, explain the value at stake and design integration around the purpose of the deal.

The strategy story so far: Sessions 1–9
Sessions 1-9 provide a chain from a chosen customer promise to a provisional corporate boundary. Session 10 makes the next distinction: a capability worth accessing is not automatically a company worth acquiring. Follow the same fictional Indian meal-service business, Nila Foods, through all nine earlier lessons. The packaging and nutrition ideas below remain proposals to test. Today compares the route, economics and integration choices needed to turn a scope argument into a defensible recommendation.
One continuing classroom story. Nila Foods is a fictional Indian meal-service for working adults. Follow its choices from Session 1; later expansion ideas are proposals to test.
Session 1 · What is strategy?
Operational effectiveness improves similar activities; strategy requires positioning, trade-offs and fit. State objective, scope and advantage, then compare intended plans with emergent action using evidence.
Nila Foods: Nila proposes preordered weekday meals on clustered routes, declines instant citywide delivery and studies actual customer behaviour.
Session 2 · Framework for Strategic Analysis
Purpose and values guide what endures, while a quantified ambition opens a same-date gap from the baseline; closing that gap requires external and internal evidence.
Nila Foods: Nila separated easing meal burdens and honest food-safety disclosure from its growth target, then compared that target with its projected baseline.
Session 3 · Industry Analysis: The Fundamentals
Industry boundaries, PESTEL and five forces connect external change to price, cost and investment; complements and possible responses then raise questions about the wider game.
Nila Foods: Nila traced ingredient-price pressure, supplier bargaining, lunch substitutes and easy entry before asking whether a neighbouring seller could also help it.
Session 4 · Beyond the Five Forces
Value nets and PARTS show how co-opetition changes added value, while uncertainty shapes commitments; credible moves therefore require examining internal strengths.
Nila Foods: Nila considered sharing a collection point with a rival and testing the rules through a limited pilot while demand remained uncertain.
Session 5 · Internal Analysis & Resource-Based View
Resources and capabilities support advantage when they improve buyer benefits or relative costs and pass tests against rivals and substitutes; value-chain analysis then checks their economic contribution.
Nila Foods: Nila examined kitchen routines, route know-how and trust, asking which linked activities rivals could imitate and whether it could retain their benefits.
Session 6 · Creating advantage and shared value
Use the value stick to distinguish value created from value captured. Test shared value against both business and social effects, including burdens shifted elsewhere.
Nila Foods: Nila asks whether demand forecasts and reusable containers reduce waste and cost, including the return and cleaning work.
Session 7 · Business Strategy: Differentiation, Cost Leadership & Blue Ocean
Porter distinguishes cost leadership, differentiation and focus; Kim and Mauborgne test value innovation; Ghemawat and Pisano examine threats, commitments and capabilities.
Nila Foods: Nila compares dependable delivery and relative cost within its chosen segment. Its value curve and four-actions proposal must demonstrate new demand and viable economics before supporting a blue ocean claim.
Session 8 · Entrepreneurship, Platforms, Technology & Innovation
Eisenmann, Parker and Van Alstyne test platform participation and pricing; Bower and Christensen distinguish disruptive trajectories from sustaining improvements.
Nila Foods: To extend its offer, Nila asks whether customers and nutrition creators could benefit from one another. An experiment tests complement quality, retained use and cross-side effects; success alone would not establish disruption.
Session 9 · Corporate Strategy: Vertical Integration & Diversification
Porter tests attractiveness, entry cost and the better-off mechanism; Campbell, Goold and Alexander ask whether this parent beats alternative owners.
Nila Foods: The ecosystem need not be owned. Nila asks whether owning a packaging supplier would improve meal delivery enough to outweigh capital, coordination and harmful misfit; contracts and specialist owners remain alternatives.
Why this leads to Session 10
Nila's packaging question now needs a route: build capability, contract, license, ally, form a joint venture or acquire. Dyer, Kale and Singh direct attention to resource interdependence, uncertainty and collaboration capability. Christensen and colleagues ask whether a deal supplies resources for the existing business or a different business model that may need protection. Compare credible alternatives, allocate responsibility for benefits, and deduct the premium and integration costs before judging buyer value.
Retrieve it before moving on
Rebuild Nila's argument from Session 1 through Session 9. If reliable packaging appears valuable, why does the chain still permit an alliance rather than an acquisition? State the capability gap, a route-selection condition, an integration boundary and evidence that would reverse your recommendation.
Compare your reasoning with a model answer
Nila's weekday promise determines its preorders, clustered routes and refusals. Purpose and a same-date gap set direction; five forces test the economics. Co-opetition and uncertainty shape a bounded office-partner experiment. Internal analysis tests coordination capabilities; activity and social ledgers test their economic and waste-reduction effects. Business strategy asks whether these support a defensible relative value-cost position. Platform analysis treats nutrition creators as a participation hypothesis. Corporate strategy then asks whether packaging ownership passes the three tests and whether Nila is a better parent. None makes acquisition inevitable. If the gap is reliable packaging access and joint design, a contractual alliance might suffice when performance is verifiable and uncertainty favours flexibility. Acquisition needs an additional control or interdependence argument, credible capabilities and value after premium and integration costs. Preserve any target routines the benefit depends on. Repeated contractual failures involving specialised assets could favour ownership; poor unit economics or capability misfit could reverse it.
Carried forward · Session 9
A scope decision still needs a route
Session 9 asked which businesses and value-chain stages belong inside the firm. Today asks how to obtain a missing capability. A promising market does not tell you whether to build, license, partner, form a joint venture or acquire. Each route changes who controls the work, who receives the upside and who bears the risk.
Synergy logic
Two activities may be more valuable together through shared assets, lower coordination costs or better customer access. Identify the specific link. “Cross-selling” is a hypothesis until a buyer actually purchases.
Core-competence logic
A repeatable skill may open a new market. Distinguish a transferable routine from a slogan: which people, systems and know-how must move, and what cannot travel?
Transaction-cost logic
Contracts require search, negotiation, monitoring and enforcement. Ownership may reduce bargaining problems when assets are specialised, but it adds bureaucracy, integration costs and the risk of destroying initiative.
The strategic alternatives
Build, borrow or buy is the start of the argument
| Route | What you gain | What you must manage |
|---|---|---|
| Build internally | Control over development and ownership of learning | Time to competence; hiring and experimentation; whether existing routines can produce the capability |
| Contract or license | Access to a defined input without owning the supplier | Quality verification, renewal, intellectual-property boundaries and switching costs |
| Strategic alliance | Complementary assets and shared learning while partners remain separate | Joint priorities, knowledge leakage, unequal effort and disputes over who captures value |
| Equity alliance / joint venture | A stronger commitment; a jointly governed vehicle in a JV | Board rights, additional funding, deadlock, performance measures and exit provisions |
| Acquire | Ownership and authority over the acquired assets | Price, approvals, cultural disruption, retention and execution of the integration plan |
Trade-off: control is valuable only if you can use it. Buying an innovative team and removing its decision rights may damage the capability you paid for. Conversely, an alliance may fail when daily decisions require coordination that the contract cannot specify.
Case evidence · Amazon in 2024
One company, several ways to obtain capability
Use the case as a set of observed choices, not proof that every choice created value. The following facts are from pages 1–3 of the assigned case; the questions are our analysis.
| Case observation | Capability question | Evidence still needed |
|---|---|---|
| AWS grew within Amazon; the case reports more than $90 billion revenue in 2023. | What internal knowledge could be recombined into a service for external customers? | Development costs, alternative routes and the timing of capability accumulation |
| Prime Video used content-licensing agreements as well as Amazon’s own production. | Which content needs ownership, and which only needs access for a period? | Renewal risk, exclusivity terms and incremental member value |
| Amazon acquired Whole Foods in 2017, gaining an established physical store network and customers. | Does a grocery store network complement delivery and membership capabilities? | Integration costs, customer overlap, retention and grocery unit economics |
| Amazon acquired One Medical in 2023 and folded Clinic into One Medical in June 2024. | Which healthcare capabilities depend on maintaining professional routines and trust? | Service quality, operating boundaries and what can safely be shared |
Do not mistake the target for the thesis
“Buy Whole Foods” names an action. A thesis says which customer problem becomes easier to solve, which activities produce the improvement and what rivals cannot reproduce easily.
Write the counterfactual
A good acquisition memo compares buying with licensing, partnering, internal development and doing nothing. Without those alternatives, almost any synergy story can sound compelling.
Decision workshop
You can buy the company. Should you?
Decision studio · illustrative numbers
How much synergy is left after you pay for it?
A target can be strategically useful and still be a poor deal at the offered price. This exercise isolates the buyer’s incremental value. All numbers below are invented, in the same monetary units, and represent present values. The target’s stand-alone value is 100.
Buyer value after premium and integration
−10.0
Realised synergy − acquisition premium − integration cost.
Change the assumptions and evaluate the deal. A positive result supports a valuation argument; it does not establish that an acquisition is the best route.
Challenge: find a plausible downside case that turns an apparently good deal negative. Then propose a price ceiling, an earn-out condition or an alliance alternative. This simplified model excludes financing, taxes, timing and legal constraints.
Synthesis
Bring a recommendation that can be challenged
A one-minute investment committee memo
Choose one Amazon move. State the capability gap, compare two routes, describe the value mechanism, identify the integration boundary and name one fact that could overturn your recommendation.
The first 100 days
Which person owns each promised benefit? What will customers and employees notice? Choose one early indicator of capability loss. A falling cost base is not reassuring if the reason customers chose the target is disappearing.
Test your reasoning before class
Can you explain why a contract is insufficient? Have you separated target quality from deal price? Does your integration plan preserve the source of value? If your claim is “culture fit”, name the actual decision, routine or incentive that conflicts.

Session 10 practice lab
An original diagram and three contexts help you test the mechanism before committing to a recommendation.
Start with the capability; end with a testable decision
The diagram in words
- 1 · Capability gap: What must improve?.
- 2 · Alternative routes: Build, contract, ally, acquire.
- 3 · Value after price: Benefits less premium and cost.
- 4 · Integration and learning: Protect what creates value.
Define the gap, compare routes, test value after price and execution cost, then set the integration boundary and monitor whether the capability survives. New evidence may change the route.
Identify the weakest link, the evidence needed and a condition that would change your recommendation.
Hypothetical · original scenario
Nila Delivery: access to a team or ownership of it?
Nila wants a regional delivery team’s route knowledge. Demand is uncertain, service quality can be measured and the team values local decision rights. A limited alliance can test the benefit and the working relationship. Acquisition may become preferable if exclusive control is essential and contracts cannot protect the required investment. Buying first is not a substitute for explaining those conditions or retaining the people who carry the knowledge.
Discuss: Which clause, milestone or result would make a pilot informative enough to revisit acquisition?
State a claim, explain its causal mechanism and point to evidence. Then identify a credible alternative explanation and one observation that would distinguish it. These prompts invite defensible interpretations; they have no automated score.
Global · Amazon / 2017 transaction
Whole Foods: connect the benefit to the activity
Amazon’s August 2017 announcement described planned Prime integration, merchandising and logistics cooperation with Whole Foods. Its subsequent filing confirms the acquisition closed on 28 August 2017. Source: Amazon announcement, 24 August 2017; completion filing. Teaching inference: those activities suggest a synergy thesis to test. An announcement does not establish realized benefits or superiority to an alliance. Use the assigned 2024 case to interrogate the economics and alternatives.
Discuss: Choose one promised activity. Who owns the benefit, what baseline is needed, and what evidence would distinguish synergy from ordinary market growth?
State a claim, explain its causal mechanism and point to evidence. Then identify a credible alternative explanation and one observation that would distinguish it. These prompts invite defensible interpretations; they have no automated score.
Indian · Tata Motors / 2 June 2008
JLR: acquisition did not eliminate every contract
The completion announcement describes Tata Motors acquiring Jaguar Land Rover, including plants, design centers, sales companies and necessary intellectual-property ownership or licenses. It also reports continuing supply and transition agreements with Ford. Source: Tata Motors/JLR announcement, 2 June 2008. Teaching inference: ownership and contracting can coexist across different activities. Identify what must be integrated, what should remain distinct and what still requires a partner. This transaction description alone does not establish the deal’s return or prescribe full integration.
Discuss: Which capability depends on acquired people or routines, and which remains supported by an external relationship?
State a claim, explain its causal mechanism and point to evidence. Then identify a credible alternative explanation and one observation that would distinguish it. These prompts invite defensible interpretations; they have no automated score.
Four diagnostic questions
Choose an answer, explain it, then use the feedback to revise your reasoning. These are original teaching scenarios and simplified calculations, separate from the existing practice bank.
Practice score: 0 / 4
Set a price or route boundary
Use the existing decision studio to create a downside case. Explain the maximum premium your assumptions permit and compare it with an alliance or internal-build alternative.
Protect the capability in the first 100 days
For Whole Foods, JLR or Nila, identify one routine worth protecting, one activity worth integrating and an early signal that integration is destroying the reason for the deal.
