The document discusses quantitative research design. It describes the research process, including identifying the research interest, formulating the problem and research questions, developing the theoretical framework and hypotheses, and designing the research plan. It also discusses different methodologies for solving problems, including the problem solving approach, management science approach, and integrated approach. These approaches involve defining the problem, generating alternatives, selecting an appropriate model, and obtaining the best solution.
