Factors of Production

Output requires inputs: in economics these are labour, capital, land, and often entrepreneurship. Labour is human effort; capital is produced goods used to produce more (machines, software, inventory); land is natural resources and location; entrepreneurship is the organising and risk-bearing that combines the others. The framework explains why some industries are labour-intensive, others capital-intensive, and why scarcity in one factor (e.g. talent, capital, or a key input) binds growth. For founders, the lens is "what is the limiting factor?" — hire, raise, or secure the bottleneck factor; don't optimise the abundant one.

Identify the scarce factor in your production function. Allocate capital and attention to that factor — hire, automate, or secure supply. Don't add more of a factor that's already slack. In strategy, ask which factor you can access or deploy better than incumbents.

Labour, capital, land, entrepreneurship: the inputs to production. Identify which factor binds your output; invest there. Use the framework to explain industry structure and your own constraint.
