A GREGGS case study

Page 7: Small-scale v large-scale tests

Testing is an expensive exercise. Although it is helpful to carry out tests on as large a sample as possible, it makes good economic sense first, to conduct a sample test using perhaps 30 people to obtain an initial reaction to a product. If it proves to be well received then large-scale tests can be carried out on samples of not less than 100 people.
