CHAPTER THREE RESEARCH METHODOLOGY3.1. IntroductionThis chapter will explain the chronological way of carrying out a comprehensive research using different research methodologies. The aim of the study will be explained by the appropriate philosophy in a correct approach and the scope model will be discussed in depth by the researcher in this chapter. This approach will be a combination of data collection procedures using both primary and secondary sources, sampling methods and research strategy. Every research has its limitations and this chapter will also discuss the limitations of the study by detecting it and comparing it with the different approach methods that can be used.3.2. Data Analysis MethodQualitative and Quantitative, these are the two types of approach to any research analysis for any data that can be used in research. The research which uses only the numbers to carry out the research analysis is called quantitative research and the research which uses the words, collection data analysis units and visual images is the qualitative research. Quantitative research is also known for its tendency to be linked to passivism, but on the other hand, qualitative research has focused and worked on the association of interpretation. Furthermore, the contrasts between involvement and lack of involvement respectively are associated by the method of analyzing qualitative data and quantitative data (Denscombe, Approach to Analysis: Quantitative and Qualitative Research, 2010). The objective of the study is to analyze the issues of supply chain management which is also known as SCM. The aim of the study is to analyze how supply chain management works for Tesco. This study also includes the direct implication relationship between the middle of the document......SS.3.9. SUMMARY In this chapter, the research methodology is combined with the analysis and explanation approach of the entire research. There are other ways of conducting research by the researcher. How to conduct the research should be determined by the researcher in this chapter by explaining all the associated logic and explanations. Supply chain management has a great impact on the current success of the business. It also develops the organizational performance of Tesco. The researcher follows the qualitative research method to collect the data and analyze the data. It includes a survey with 20 questionnaires among 100 groups of people followed with 10 face-to-face interviews. Most people in this group are employees, managers and a few customers. Most data is collected from the primary source, increasing accuracy and analysis strength..
