This article explores the concepts, types, stages, and advantages of research and development (R&D) in the context of scientific inquiry. R&D is a systematic approach used to address human problems, aiming to produce innovative products or models. The study employs a systematic literature review to analyze existing theories and research on R&D. The findings indicate that R&D procedures are designed to generate new innovations, starting with problem analysis, followed by design and development, implementation, and evaluation. The process involves multiple validations and trials, ensuring the product or model's reliability and effectiveness. R&D is particularly valuable in education for developing teaching models, training modules, and curricula. Key characteristics of R&D include problem-based product development, product testing, validation, and revision. The article also discusses various R&D models, such as Borg and Gall, 4D, ADDIE, and Richey and Klein, each with distinct stages and advantages. These models emphasize systematic problem analysis, product development, and evaluation to ensure the effectiveness of the resulting products or models. The study highlights the importance of R&D in addressing real-world issues and improving educational practices through innovation and scientific validation.This article explores the concepts, types, stages, and advantages of research and development (R&D) in the context of scientific inquiry.
