Advantages: As trials are conducted in a small area, a business may save money by having a trail for a product or service, just in case it finds out that customers don't want what the business has for sale
Disadvantages: Trials are still costly to set up
The area chosen must fully reflect the target market of the business, if not then money will be wasted
The business may conduct a trail and only find out what they first thought
Advantages: Because focus group are chosen to represent the target market for a business, the data from them is usually very accurate and can be relied upon to make important decisions
Disadvantages: Focus groups, though carefully chosen, are still small groups which makes the collection of data from them more expensive per person than interviews or questionnaires
The selection of people to take part in the focus group is time consuming and so costly
Qualitative data is usually collected using primary research methods, often with interviews or the use of a focus group, although secondary research could be used as well
