A difference is economically useful only if a target customer perceives and believes it, then changes behaviour: preference, conversion, accepted price, frequency or retention. A visible feature that is not valued adds cost and complexity without advantage. Build a bridge from attribute to evidence, quantified customer benefit, exposed population, behavioural change and net contribution, then compare it with a simpler option.
Decision and method.
Fund differentiation when its risk-adjusted incremental contribution exceeds full cost and credible evidence makes it ownable. Name the replaced product, process or non-consumption; measure its total price, use cost, risk and friction. Link attribute to proof, benefit and economic unit, then estimate the share of target customers who encounter the problem, understand proof and value the gain. Test choice, willingness to pay, retention or use with an appropriate protocol and distinguish stated, simulated and actual behaviour. Close the supplier account with incremental revenue or retention, margin, production, service, proof, complexity and cannibalisation; compare a full option with proof-only or lighter variants.
Worked example.
A software publisher considers a feature that saves 6 hours a month for 35% of 4,000 customers, valued at €45 an hour. Development costs €900,000, maintenance €120,000 annually, and 28% of affected customers would pay €18 more per month. Paying customers: 4,000 × 35% × 28% = 392. Annual revenue: 392 × 18 × 12 = €84,700, well below cost. Yet a 3-point expected churn reduction among 1,400 affected customers protects 42 customers at €6,200 annual margin: €260,400. Total annual value: €345,100; after maintenance: €225,100; at 60% confidence: €135,100 adjusted value. Do not launch full development: pilot a €140,000 connector capturing 70% of benefit; its adjusted net value reaches €186,000 in year one.
Checks and limits.
Quantify the alternative and genuinely affected population; make evidence connect attribute to observable benefit; include price, conversion, retention and full costs in one account; compare a lighter option before irreversible investment. Stated willingness to pay often overstates real behaviour; symbolic benefits resist monetary conversion; competitors can shorten appropriability sharply.
