Offer an answer worth sharing information for
An assessment should return something personally useful in exchange for a prospect's time and information, rather than simply collect contact details. The value might be expert advice, industry benchmarking information or a personalised answer to a business challenge.
Choose the format according to the answer the prospect needs. A calculator takes business information and generates an answer, often numerical. An assessor uses targeted questions to produce a report. A configurator lets someone personalise a product or service around their needs. The practical starting point is the benefit the prospect receives: define that benefit before deciding what information to request. Personalised guidance gives the interaction value whether or not the prospect becomes a customer.
