Demand Analysis
Use when asked to run or explain a demand analysis — estimating and understanding customer demand for a product or service (market size, price sensitivity, demand drivers) — as the market-feasibility input to a broader feasibility-analysis or business case.
Demand analysis studies and estimates customer demand for a product or service — how many people want it, how much they'd pay, and what drives that demand to rise or fall — providing the market-side evidence a business case or Feasibility Analysis needs.
Key questions demand analysis answers
- Market size — how large is the total addressable demand, and what portion is realistically reachable?
- Price sensitivity — how does demand change as price changes (elasticity), and what price point balances volume against margin?
- Demand drivers — what factors (seasonality, economic conditions, complementary products, substitutes, demographic trends) push demand up or down?
- Segment variation — does demand differ meaningfully across customer segments, geographies, or use cases?
Common methods
- Primary research — surveys, interviews, and direct customer feedback (see Voice of the Customer) to gather firsthand demand signals.
- Secondary research — industry reports, published market sizing, and competitor data as a starting estimate.
- Historical/analogous data — demand patterns for comparable existing products, adjusted for relevant differences.
- Pilot testing — small-scale, real-world tests (a limited launch, a landing page measuring signups) that generate actual behavioral data rather than stated intentions alone.
Why stated intent isn't enough
Demand analysis works best when it goes beyond simply asking people whether they'd buy something — stated purchase intent is a notoriously unreliable predictor of actual behavior. Where possible, favor methods that observe real behavior (pilot tests, pre-orders, actual willingness to pay) over surveys asking hypothetical questions alone.
Common pitfalls
- Relying solely on stated intent surveys — "would you buy this?" responses systematically overstate actual future purchasing behavior.
- Ignoring price sensitivity — estimating demand at one assumed price point without testing how demand shifts at different price points can produce a misleading market-size estimate.
- Treating the total addressable market as the realistic near-term opportunity — the theoretical maximum market size is rarely what's actually reachable in a given timeframe with realistic resources.
