Business research involves applying the scientific method to study business phenomena in order to maximize sales and profits. It can explore any business issue, such as determining which products are most profitable. Managers determine when to conduct research based on time, data availability, the nature of decisions, and the benefits versus costs of the research. There are quantitative and qualitative research approaches, with quantitative using things like surveys and statistical analysis and qualitative using techniques like interviews. Both basic and applied research are important, with basic research increasing knowledge and applied research solving problems. Good research is systematic, logical, empirical, and replicable.
