Business research is defined as the systematic and objective process of gathering information to aid managerial decision making. There are two main types of business research: basic research which expands knowledge without solving a specific problem, and applied research which addresses real-life business problems. Business research should not be haphazard, must be objective, and helps reduce uncertainty in decision making. It is important to consider time constraints, available data, the nature of decisions, and whether research benefits outweigh costs when determining whether to conduct business research.
