A wide range of methods are available for systematically gathering information as part of a market investigation. The selection depends on the specific question, the budget and the depth of data required. Basically, the methods can be divided according to various criteria: The examination period: market analysis & market observation Market analysis: examines the market at a specific point in time. It provides a snapshot of the current situation (e.g. market size, competitors, customer structure now). Market observation: Follows developments in the market over a longer period of time. It is used to identify trends, changes and dynamics. The origin of the data: Primary research & secondary research Secondary research (Desk Research): Evaluation of existing data that was originally collected for other purposes. Primary research (field research): Targeted collection of new data specifically for the current question. Independent primary research becomes necessary when secondary data is insufficient, outdated or not specific enough. The type of data collection (methods of primary research) There are various established methods within primary research: Survey: The most common method. Can be done in writing (questionnaire), orally (interview), by telephone or online. Suitable for collecting opinions, attitudes, knowledge and behavior. Expert interviews provide in-depth qualitative insights. Observation: Systematic recording of visible behaviors, processes or objects, without direct interaction. Examples: Path analysis in stores, analysis of online user behavior, observation of competitive activities at trade fairs. Experiment / market test: Targeted investigation of cause-effect relationships under controlled conditions. Examples: Product tests with different variants, A/B tests of websites, price tests in selected regions (test markets). Panel studies: Repeated surveys or observations of a consistent group of people or companies over a longer period of time. Enables the analysis of developments and changes over time (e.g. consumer behavior, brand preferences). The approach to analysis: Qualitative vs. Quantitative methods Quantitative methods: The aim is to make facts measurable and express them in numbers. Large, often representative samples are examined in order to obtain statistically reliable results (e.g. "How many percent of the target group know brand X?"). Typical methods: Standardized questionnaires, quantitative observations. Qualitative methods: The aim is to understand motives, attitudes, opinions and deeper connections. Smaller samples are examined intensively (e.g. “Why do customers prefer brand X?”). Typical methods: in-depth interviews, focus groups, qualitative observations. In practice, different methods are often combined in order to obtain the most comprehensive picture possible.
