I attended the seminar about Chapter 3 Methodology, and the host, Sir Carino, discussed with us what to do with the Methodology. I learned a lot in this seminar, and it became my guide to do and follow the sections of the chapter. It is important to choose the right model for software development and use Qualitative Research, Quantitative Research and Mixed Research methods. It discussed the topics in Chapter 3, data flow diagrams, and emphasized the importance of direct observation, focus groups, and interviews for data collection. The need for methodological rigor and careful research design is emphasized, offering practical advice on effective thesis production. In summary, the seminar thoroughly understood research processes and offered valuable tips for conducting solid research in both academic and professional contexts.
