The Core Functional Areas
- Operations: producing and delivering the product/service.
- Finance: managing money, budgets and reporting.
- Marketing & sales: finding customers and winning orders.
- Human resources: hiring, training and retaining people.
- Strategy & leadership: direction, structure and performance.
How They Interconnect
Marketing generates demand that operations must meet; finance funds both; HR supplies the talent; strategy aligns everything. Breakdowns in one area ripple through the rest.
Why It Matters
Working on the wrong function wastes effort. Identify the bottleneck and fix the weakest link.
