One of the most used market tests is called focus groups. This method can also be used for the assessment of a packaging in relation to optimal packaging and the Packaging Directive.
Because this is an excellent method and also simple to perform you will on the next pages get an instruction in how to make your own focus group assessments.
You have to decide if you will use a professional market research company or you will educate yourself to perform the test. Our advice to you is to be present during the interview yourself because you will get so much detailed information, which is impossible for the market research company to write in a report. And after some training you are able to plan and perform a focus group well.
