Where and how information is generated: As in all disciplines of market research, there are many ways to obtain information in competitor analysis: internal or external research, primary or secondary data, qualitative interviews or quantitative surveys. Possible sources: Press releases, paid and free market and industry studies, the Federal Gazette, annual reports, credit agencies, etc. or surveys of customers and sales employees can serve as a source of information relevant to competition. Quality and validity: Unfortunately, these sources have limits in their availability and informative value. It is usually difficult to check the validity of the information. Tip: When carrying out a reliable competitor analysis, it is advisable to benchmark the internally generated information through external interviews. Competitively relevant information in particular can often only be generated through interviews, which cannot be carried out by the company itself. This can be done, for example, by a professional market research company.
