How organisations work, how decisions get made, and what the MBA actually teaches
Management is the practice of getting things done through other people inside resource constraints. It is not the same as leadership, and it is not just "being in charge." This module gives you the mental model an MBA provides across seven parts: the history of management as a discipline (Part A), strategy and competitive positioning (Part B), the financial numbers every manager must read (Part C), marketing and customer logic (Part D), operations and supply chains (Part E), organisational behaviour and people (Part F), and startup/entrepreneurship contexts where the rules change (Part G). By the end you will be able to follow a board presentation, interrogate a strategy deck, and understand why most change programmes fail.
Management is the coordination of people and resources toward a defined objective. The single most important word in that definition is "through" — a manager's output is not their own work but the work of their team. This makes management fundamentally different from individual expertise. The classic distinction: a great surgeon is not automatically a great hospital administrator. Henry Mintzberg's 1973 research on what managers actually do exploded the tidy myth of rational planning — he found that managers spend most of their time in brief, fragmented verbal interactions, not long-horizon strategy. Management is reactive, relational, and interpersonal far more than the textbooks admit.
Management is about execution inside known structures — planning, organising, controlling. Leadership is about changing the structures themselves — vision, alignment, inspiration. John Kotter argues most organisations are over-managed and under-led: they execute plans efficiently but adapt slowly. Both are necessary; neither substitutes for the other.
Henri Fayol, a French mining executive, identified the four functions that still define MBA curricula: Plan, Organise, Lead, Control (POLC). His 14 principles of management — including unity of command, division of labour, and scalar chain — were the first systematic account of how large enterprises should be run. Remarkably durable for a 110-year-old framework.
Poor management is enormously costly. A 2023 Gallup study found that managers account for 70% of the variance in employee engagement. Bad management does not just make people unhappy — it directly destroys productivity. The World Bank estimates that management quality explains roughly 30% of the productivity gap between rich and poor countries.
The MBA was invented at Harvard Business School in 1908, drawing from engineering's case-study tradition at MIT. The degree teaches a common language for analysing business problems across domains: accounting, finance, marketing, operations, strategy, and organisational behaviour. Its central pedagogy — the case method — puts students in the seat of a real executive and demands a decision, not an analysis. The two-year residential MBA at a top school costs around $200,000 in fees and foregone salary, yet median starting salaries at Harvard and Wharton exceed $175,000, and the long-run earnings premium is positive but shrinking as management content migrates online. The MBA's biggest non-financial return is the alumni network: the specific people you meet, not the credential itself.
Michael Jensen and William Meckling's 1976 paper "Theory of the Firm" gave corporate governance its central concept: the principal-agent problem. Shareholders (principals) cannot perfectly monitor managers (agents), so managers may pursue their own interests — empire building, excessive perks, risk avoidance — at the expense of shareholders. The proposed solution was to align executive incentives with share price through stock options and performance-linked pay. For two decades this drove every major corporate reform: hostile takeovers, leveraged buyouts, the rise of activist hedge funds, and the relentless focus on quarterly earnings. Jack Welch of GE was the era's icon — quadrupling GE's market cap while systematically exiting low-return businesses. The crack appeared in 2001–2002: Enron and WorldCom showed that stock-option incentives could motivate accounting fraud as easily as genuine value creation. In 2009, Welch himself called shareholder value maximisation "the dumbest idea in the world." The 2019 Business Roundtable statement — signed by 181 US CEOs including Apple, Amazon, and JPMorgan — formally declared that corporations exist to serve all stakeholders, not just shareholders. Whether the declaration changes behaviour is contested: buybacks remained near record levels the following year.
Bars show the dominant period of each school's influence, not its precise origin or death date. Eras overlap — they do not replace one another cleanly.
Strategy is a coherent set of choices about where to compete and how to win that are mutually reinforcing. The key word is "choices" — strategy is fundamentally about what you will NOT do. IKEA chose flat-pack furniture, self-assembly, and vast suburban stores. That ruled out premium service, small-city locations, and delivery. Each choice reinforced the others. Michael Porter's 1996 "What Is Strategy?" remains the clearest articulation: strategy is about making trade-offs, creating fit among activities, and achieving a position that is hard to imitate.
Planning is a schedule for deploying resources you already have. Strategy is deciding which resources to build and which arena to enter. Henry Mintzberg's 1987 "5 Ps for Strategy" showed that strategies can be deliberate (planned in advance) or emergent (patterns that crystallise from a stream of decisions no one explicitly intended). Honda's conquest of the US motorcycle market in the 1960s was famously emergent: their executives arrived with large bikes, found customers more interested in the small Supercub they used as runabouts, and pivoted. The strategy emerged from the market, not the plan.
Porter introduced the Five Forces in his 1979 Harvard Business Review article. The framework analyses structural profitability of an industry — before any firm-level strategy. The weaker the forces, the more attractive the industry. Cigarettes score exceptionally well on all five (low buyer power, high switching cost, tight supply chain) — which is why Philip Morris earned a 30% net margin for decades.
Three internally consistent positions exist. Attempting to occupy two simultaneously — "stuck in the middle" — is the most common strategic failure. Companies that try to be both low-cost and highly differentiated typically achieve neither.
Blue Ocean Strategy (Kim and Mauborgne, 2005) adds a fourth path: compete in uncontested market space by simultaneously lowering cost and raising value. Cirque du Soleil eliminated animals and arena touring (cost) while adding theatrical narrative (value) — creating a new audience that had never bought circus tickets.
Source: Bain & Company "Management Tools" survey data, approximate figures. SWOT's dominance is partly its simplicity — it requires no data and can be completed in a meeting, which is also its biggest weakness.
Use it for a fast snapshot: internal strengths and weaknesses against external opportunities and threats. The danger is producing a tidy list without making a choice.
Use it when the outside world is moving: politics, economics, society, technology, law, and environment. It is especially useful in regulated sectors such as energy, banking, and healthcare.
Use it to locate advantage inside activities: logistics, operations, marketing, sales, and service. IKEA's edge is a fitted chain of design, flat-pack logistics, stores, and customer assembly.
Use it for portfolio logic: cash cows fund question marks, stars need investment, and dogs consume attention. It is crude, but it forces capital allocation into view.
Clayton Christensen's 1997 "The Innovator's Dilemma" identified a pattern: established companies are consistently defeated not by direct competitors, but by entrants who first serve overlooked, less demanding customers with cheaper, simpler products — then improve rapidly until they can displace the incumbents from above. Hard-disk drives illustrated this perfectly across seven generations. Each time, the smaller-drive maker started "worse" on the incumbent's metrics but ultimately won. The mechanism is rational and tragic: incumbents are listening to their best customers, who always say "give us more performance," leaving the low end undefended.
Jill Lepore's 2014 New Yorker critique hit a genuine weak point: Christensen cherry-picked cases and his theory is unfalsifiable — any failure can be labelled "disruption" retrospectively. Christensen's response was to tighten the definition. True disruption starts at the low end (Steel minimills undercutting integrated mills with rebar) or in a new market that non-consumers can now afford (Sonos vs high-end hi-fi). Netflix was initially new-market (DVD mail vs no-rental) then migrated upmarket. Uber is not technically disruptive by Christensen's definition — it targeted the same taxi customers from day one, not a new-market entry.
Net income from the income statement flows into retained earnings on the balance sheet. The cash flow statement begins with net income and reconciles it to actual cash by adding back non-cash charges (depreciation) and adjusting for working capital changes. A company can be profitable and still run out of cash — the 2001 Enron collapse and dozens of retail failures demonstrate this. Investors obsess over free cash flow (operating CF minus capex) because it is harder to manipulate than earnings: cash either arrived in the bank account or it did not.
Gross margin = gross profit / revenue. Software businesses can have 75-90% gross margins because serving one more customer is cheap. Grocery retailers may run below 5% net margin, so inventory turns and supplier terms matter more than glamour.
Current ratio = current assets / current liabilities. A profitable company can still die if bills come due before cash arrives. Working capital is a management issue, not just an accounting footnote.
Debt magnifies outcomes. Debt can improve returns when cash flows are stable, as in utilities or real estate. It becomes dangerous when revenue is cyclical and interest payments are fixed.
Three primary methods exist, each suited to different contexts. Discounted Cash Flow (DCF) values the business as the sum of all future free cash flows, discounted at the weighted average cost of capital (WACC). It is theoretically correct but brutally sensitive to assumptions: a 1% change in discount rate or long-term growth rate can swing the output by 30–40%. Comparable company analysis (comps) values the business by applying multiples (typically EV/EBITDA or P/E) from similar public companies. It is market-relative, not intrinsic. Precedent transactions (precedents) use multiples paid in past M&A deals — typically 20–30% higher than comps because buyers pay a control premium. In practice, bankers run all three and present a "football field" showing the overlapping range.
Unit economics measures profitability per single customer or transaction, stripped of fixed costs. Customer Acquisition Cost (CAC) is how much you spend to acquire one customer. Lifetime Value (LTV) is the net revenue that customer generates over their relationship with you. The LTV:CAC ratio is the single most important metric for subscription and recurring-revenue businesses. Venture investors expect a ratio above 3:1; below 1:1, the business destroys value with every sale. Payback period is CAC divided by monthly gross profit per customer — if you spend $300 to acquire a customer who pays $30/month at 50% margin, payback is 300/(30×0.5) = 20 months. Amazon's 1997 shareholder letter was the first systematic public articulation of this logic: sacrifice short-run profit to build durable customer relationships with favourable long-run economics.
Illustrative, not a universal benchmark. Mature public SaaS companies vary widely: high-growth firms reinvest nearly all margin into sales and marketing, compressing operating profit to near zero. The "Rule of 40" (revenue growth % + operating margin % ≥ 40) is the heuristic investors use to assess whether growth spend is justified.
Marketing is the function of understanding customer needs and designing offers that profitably satisfy them. It is not advertising (a subset of promotion), not sales (a downstream execution of marketing decisions), and not branding (a component of positioning). Peter Drucker put it precisely: "The aim of marketing is to know and understand the customer so well the product or service fits him and sells itself." The 4 Ps (Product, Price, Place, Promotion) — introduced by E. Jerome McCarthy in 1960 — remain the dominant organising framework. More recent variants add People, Process, and Physical Evidence (for services), producing the 7 Ps. The STP process (Segmentation, Targeting, Positioning) precedes the 4 Ps: you cannot set a price without first deciding who you are targeting.
Most marketing failures happen in the first two stages, not execution. Companies launch beautiful campaigns targeting "everyone" with an undifferentiated message. The most expensive word in marketing is "everyone."
Brand equity is the premium a customer will pay for a branded product over a functionally equivalent generic. David Aaker's model decomposes it into brand awareness, perceived quality, brand associations, and brand loyalty. Coca-Cola's brand equity is estimated at $57 billion — the gap between its physical assets and market value is almost entirely brand. The counterintuitive truth: brand equity is built by consistency over decades, not by campaign spend. Johnson & Johnson spent 60 years earning trust and destroyed a decade of it in the 1982 Tylenol poisoning crisis — then rebuilt it in 10 weeks through transparent crisis management, demonstrating that authenticity is the active ingredient.
The AIDA model (Awareness, Interest, Desire, Action) was developed by E. St. Elmo Lewis in 1898 and is still valid. Modern variants add Loyalty and Advocacy — turning customers into active promoters. The critical measurement insight: acquiring a new customer costs 5–7x more than retaining an existing one. Yet most marketing budgets are tilted toward acquisition. Amazon Prime, launched in 2005, is the most successful retention programme in retail history — members spend 2.5x more annually than non-members and churn at under 6% per year.
Rounded industry estimates. "Digital" includes search, social, video, display, retail media, and classified platforms, so one large category hides several different advertising markets.
More specific segmentation yields higher conversion rates but smaller addressable markets. B2B SaaS companies typically segment by firmographic (company size, industry) then layer on behavioural data. Consumer brands often lead with demographic then refine with psychographic.
Operations management is the design and control of production and delivery processes. Its core insight — from Eliyahu Goldratt's "The Goal" (1984) — is the Theory of Constraints: every system has one binding constraint that limits throughput, and improving any non-constraint yields no system improvement. McDonald's perfected this: their constraint is the grill, so every other process (order-taking, assembly, delivery) is designed to never let the grill sit idle. When McDonald's introduced electronic ordering kiosks, throughput increased not because ordering got faster but because the order mix shifted toward more profitable, grill-utilising items.
Apple's iPhone supply chain spans over 200 primary suppliers across 43 countries. The bullwhip effect describes how small demand variations at the customer end amplify into wild swings at the raw-material end — a 10% sales fluctuation at Walmart can translate to a 40% production swing at a Tier-2 electronics supplier. Just-in-time (JIT) manufacturing, pioneered by Toyota, eliminates buffer inventory to expose problems immediately — but creates catastrophic fragility. The 2011 Thailand floods and 2021 semiconductor shortage revealed that decades of JIT optimisation had produced supply chains with essentially no redundancy.
Six Sigma's 3.4 DPMO target equates to 99.99966% defect-free. For a factory producing 1 million units per day, that is 3 defects. Motorola introduced Six Sigma in 1986 after quality problems nearly destroyed the company; GE under Jack Welch adopted it in 1995 and claimed $12 billion in savings over five years.
Five tiers from physiological needs to self-actualisation. Influential but poorly supported empirically: there is no evidence that lower needs must be satisfied before higher ones activate, and the hierarchy does not predict behaviour across cultures. Its lasting value is the reminder that workers are whole human beings with complex needs — radical in 1943 when most managers thought pay was the only variable.
Frederick Herzberg distinguished hygiene factors (salary, working conditions, job security) from motivators (achievement, recognition, responsibility, growth). Hygiene factors prevent dissatisfaction but do not create motivation. Removing pain is not the same as creating joy. The practical implication: managers who want to motivate should enrich jobs, not just improve benefits. Many companies have inverted this — lavish offices and perks but no autonomy or growth.
Deci and Ryan found that intrinsic motivation requires three conditions: autonomy (I choose to do this), competence (I am good at it), and relatedness (it connects me to others I care about). Adding extrinsic rewards to intrinsically motivated tasks can "crowd out" intrinsic motivation — the overjustification effect. A study of Israeli blood donors found that paying donors for blood reduced donations: once framed as a transaction, the altruistic motivation disappeared.
Daniel Pink's synthesis in "Drive" (2009) distilled the evidence: for mechanical tasks, money motivates. For cognitive tasks requiring creativity and judgement, autonomy, mastery, and purpose motivate more. This finding has replicated robustly. The paradox of high-paying knowledge-work organisations with disengaged employees is explained here: pay above a threshold satisfies hygiene but does not build motivation. Google's 20% time policy, which produced Gmail and AdSense, applied this principle explicitly.
Hersey and Blanchard's situational leadership model argues no style is universally best — the optimal style depends on the follower's competence and commitment level for a specific task. A new hire needs directive leadership on their first week regardless of their seniority elsewhere.
Bruce Tuckman's 1965 model remains the most used framework for team development. The critical insight: storming is inevitable and healthy — suppressing conflict prevents the team from developing genuine norms. Leaders who rush to performing without allowing storming create false harmony that collapses under pressure. Google's 2012 "Project Aristotle" study on 180 teams found that psychological safety — Amy Edmondson's concept that team members can take interpersonal risks without fear of punishment — was the single biggest predictor of team effectiveness, outranking individual talent, compensation, and management style by a wide margin.
Edgar Schein's model has three levels: artefacts (visible behaviours, symbols, office design), espoused values (official statements of belief), and underlying assumptions (unconscious, taken-for-granted beliefs that drive actual behaviour). Culture change fails when it targets only artefacts — new slogans, away days, rebranding — without touching underlying assumptions. Peter Drucker's alleged aphorism "culture eats strategy for breakfast" is slightly misleading: strategy and culture are not adversarial. The deeper truth is that no strategy can be executed by a culture that contradicts it. Amazon's written six-pager meeting memos are not just a communication tool — they are a cultural artefact that enforces analytical rigour as an assumption, not a policy.
Percentages do not sum to 100% as multiple biases typically co-occur in the same decision. Source: McKinsey Quarterly research on strategic decisions. The most actionable debiasing technique is the pre-mortem: before committing, ask "assume this project has failed spectacularly — what went wrong?"
Steve Blank's key insight: a startup is not a small version of a company — it is a temporary organisation searching for a repeatable, scalable business model. The management task is discovery, not execution. Corporate management tools — budgets, performance reviews, annual plans — are designed for executing a known model, not finding an unknown one. Applying them to a pre-product-market-fit startup produces the illusion of rigour while killing the iteration speed needed to survive. Product-market fit (PMF) — Marc Andreessen's term for the moment when a product satisfies a strong market demand — is the only milestone that matters before Series A.
Eric Ries's Lean Startup framework formalises the build-measure-learn loop as the core startup process. A pivot is a structured course correction that tests a new hypothesis about the product, business model, or customer segment — not an admission of failure. YouTube started as a video-dating site. Instagram as a Foursquare-style check-in app. Slack as an internal tool inside a gaming company. The companies that pivoted survived; the companies that "stayed the course" on a wrong hypothesis did not. The distinguishing characteristic of successful pivots is that they preserve a working component from the previous iteration rather than starting from scratch.
VC economics follow a power law: a single fund-returning investment (a "fund maker") must return the entire fund to be worth the portfolio. A $200M fund needs at least one exit producing $200M+ in proceeds. This explains why VCs push for aggressive growth — the 20 companies that do not break out are write-offs; only the outliers matter.
