Page 9: Large-scale tests

New product development should be consumer-led. Once a small-scale test provides positive results then product testing needs to be carried out on larger representative samples of real consumers. A market research agency will carry out the detailed survey for the company. The larger the sample of respondents who test a product, the more reliable and representative of the population as a whole the results will be.

It is vital to test a product amongst as large a sample of the target market as possible whilst remaining within the financial and time constraints of the project. Conducting 100 interviews in a day is regarded as a reliable sample size for a product taste test.
