Strategy to the balance sheet

Business and management study how organisations create value and get things done — strategy, marketing, finance, operations, and the people who run it all. It's the practical craft of turning an idea into a working enterprise, and it borrows from economics, psychology and hard experience.

Learned critically, it's genuinely useful; learned uncritically, it's a parade of fashionable buzzwords. This node aims for the former. Set your level below.

A map of Business & Management

How organisations work

The functions that make an enterprise run.

  • Strategy — how a business chooses where and how to compete.
  • Marketing — understanding and reaching customers.
  • Finance & accounting — the language of money and value.
  • Operations & supply chains — actually making and delivering things.
  • Organisational behaviour & leadership — the people who do the work.
  • Entrepreneurship, innovation & ethics — building new things, responsibly.
§03

The canon

The thinkers who shaped management

Real figures and ideas.

  • Adam Smith — the division of labour, at the root of it all.
  • Frederick Taylor — "scientific management," and the drive for efficiency (for good and ill).
  • Peter Drucker — effectively invented modern management as a discipline.
  • Michael Porter — competitive strategy and the "five forces."
  • W. Edwards Deming — quality management, hugely influential in manufacturing.
  • Clayton Christensen — "disruptive innovation," and why great firms fail.
§04

The live debates

The debates business argues about

Real, consequential disagreements.

  • Shareholders or stakeholders? Whether a company exists to maximise profit, or to serve a wider set of interests — the central argument of modern business.
  • Does management theory work? Or is much of it repackaged fashion?
  • Is leadership born or made?
  • Short-term vs long-term. The pressure of quarterly results against building to last.
  • Is "business ethics" a contradiction? The uneasy relationship between profit and principle.
§05

Where to start

A route in

A route in — everything runs from the panel above.

  1. Run Orientation on strategy, or on how a business actually works end to end.
  2. Use Great Debates on shareholders vs stakeholders.
  3. Apply it with Real-World Applications to a company you know well.
  4. Read Drucker or Porter — and read management fashion with a raised eyebrow.

For every framework, ask: is there evidence this works, or does it just sound clever?
