Case Studies, Checklists, Interviews, Observation sometimes, and Surveys or Questionnaires are all tools used to collect data. The research may also continue for an extended period of time, so processes and developments can be studied as they happen. In this research, interviews are carried out with three managers, three local customers and four employees, representing small convenience samples of each category, which allows the researcher to gain in depth information about the topic. Case study method is responsible for intensive study of a unit. Data collection methods can be divided into two categories: secondary methods of data collection and primary methods of data collection. Create data repository The interview is preceded by a note of confidentiality and is conducted on a one to one basis for the three managers, three part-time international service employees and three customers. This incorrectly confuses the case study method with a specific method of data collection, such as ethnography or participant observation. It helps a researcher to understand a complex issue or object and add strength to what is already known through previous research. Surveys, observations, archival research and secondary data collection can be quantitative or qualitative methods. Prosser as follows "there is still no man that would not accept dog tracks in the mud against the sworn testimony of a hundred eye witnesses that no dog had passed by." The results are corroborated with sufficient evidence showing that all aspects of the problem have been adequately explored. The methods of doing these forms of data collection do not differ markedly from similar methods across all qualitative approaches. Most case studies use multiple methods of collecting data, such as interviews, surveys, observations, document review and, occasionally, the collection of physical artifacts. The data collection method starts with the activity of sampling. If data are collected haphazardly, it will be difficult to answer our research Collection of large data requires greater planning and organization ; Different types of data triangulation. It studies a social unit in its entire perspectives.

Data collection techniques include interviews, observations (direct and participant), questionnaires, and relevant documents ( Yin, 2014 ). Semi structured questionnaires include open ended questions and call for a subjective information while structured questionnaires tend to be close ended and seek for objective responses based on, for example, Likert scale measures. In order to ensure objectivity and clarity, a researcher should adopt a methodical approach to case studies research. There are various methods of collecting primary, quantitative data. Data triangulation; The easiest method to implement uses a variety of information or data sources in order to increase the validity of the results. However, in this case-study, primary information is gathered through semi-structured interviews to gather in-depth insights about the issues relevant to the research objectives. The case study is a data collection method in which in-depth descriptive information about specific entities, or cases, is collected, organized, interpreted, and presented in a narrative format. Every interview lasted for about 45 minutes. Case studies involve a detailed contextual analysis of a limited number of events or conditions and their relationships. These form the core of their inquiry—the staples of the diet. Case study research is a qualitative research method that is used to examine contemporary real-life situations and apply the findings of the case to the problem under study. Interviews/focus groups and ethnography are qualitative methods. Sampling is about selecting a small set of respondents who represent the entire population. The research design takes the following aspects in consideration: to devise the relevant questions upon which the study proceeds, to identify what data is relevant, to have a clear idea of what data is  to be collected and finally to analyse the given data according the research problem. Secondary sources of information are less time consuming to access, however the choice of such sources depends on their relevance to the research questions. ON THE CASE STUDY METHOD The case study method embraces the full set of procedures needed to do case study research. Non probabilistic sampling is that type of sampling where the researcher has minimal control of whom being selected for the research. The investigation may be of a single person, business, event, or group. Preface This technical report is based on a panel discussion conducted at the 1996 meeting of the Association for Health Services Research. Quantitative data collection methods, on the other hand, deal with numbers and are highly standardized. 4 It refers to gathering information about a particular individual or a group in order to gain a holistic view about the subject of study .A case study approach is a holistic approach to observe the situation and gather valuable insights from the participants in the situation to explore phenomena. are used to help the investigators to approach the data from different ways and thus avoid making premature conclusions. The research object would be a person, a program, an event or an entity. The following steps can be followed: Identify and define the research questions - The researcher starts with establishing the focus of the study by identifying the research object and the problem surrounding it. In general, primary or secondary data pertaining to these research questions can be used as a mode of data collection process. These studies are a type of qualitative design that rely on observation, narratives and descriptive data. In 7 of the 32 participating sites, survey data collection was followed by targeted qualitative focus group data collection during intensive site visits, ranging from 2 to 4 days in length.

Required fields are marked *, 7 The data collection process revolves around these research questions taking the case of Sainsbury in this study. A case study approach is particularly chosen when there does not exist much prevalent theory about the situation. The survey method of data collection is a type of descriptive research, and is likely the most common of the major methods. Weaknesses Case studies involve analysis of small data sets, such as one or two companies, that ... • If changes need to be made to the data collection procedure, these changes need to be recorded and documented. (None of the tasks, nor the For interviews or surveys, subjects must be contacted and scheduled. The information gathered directly from the respondents is considered as a primary source of information. The practice of data collection proceeds in the lines of the identified research questions whose answers can potentially solve the research problem. Case study method of Data Collection. In addition, the research presents the researcher with the rich opportunity of personal experience and engagement with the study case where the personal experiences and insights play a crucial role in understanding the phenomena. The right one to use depends … Exploratory case study data collection method is often accompanied by additional data collection method (s) such as interviews, questionnaires, experiments etc. … The secondary source of information aims at gathering information which, although relevant,  is not directly related to the topic of the research. In these techniques, demand is forecast based on … The sampling technique used here is non-probabilistic purposive sampling. This is the design phase of the case study method. Case studies are sometimes classified into three categories known as exploratory, descriptive and explanatory case studies. observations & interviews). A case study is an in-depth empirical investigation of a situation to understand and answer the how and why questions pertaining to a particular phenomenon. Observation is a popular method of data collection in behavioral sciences. The participants may represent a cross section of population or may be a set of target groups which are chosen by researcher according to his/her discretion. Select the cases - In this step the researcher decides on the number of cases to choose (single or multiple), the type of cases to choose (unique or typical) and the approach to collect, store and analyze the data. The investigation involves collecting in-depth data about the individual entity through the use of several collection methods. The research design includes the conceptual framework of the research process which involves the data collection process and the sampling techniques employed for the conduct of the research. In most cases, data collection is the primary and most important step for research, irrespective of the field of research. There are two types of data - primary and secondary The primary data are collected fresh and for the first time from the field. Data Collection is a process to find out the answer for the research problem. There are five different types of triangulation which will be explained briefly over here. •In the collection of data we have to be systematic. case study: Research performed in detail on a single individual, group, incident or community, as opposed to, for instance, a sample of the whole population. Case studies are characterized by setting, context or environment, and holistic data collection methods and are used to inform theories, design future studies and develop interventions based on context. These steps do not imply that this approach is the only way case study data can be analysed (Barry, 1998) and it is recommended that they be used in conjunction with the overall case study design frameworks proposed by Yin (1994); and Miles and Huberman (1994). This is the design phase of the case study method. .hide-if-no-js { Face-to-face interviews, qualitative questionnaires, focus groups, observation, longitudinal studies, and case studies are examples of qualitative data collection methods.

Of which limit few unprecipiced archaisers mispractised on case study data collection methods top of no one exsanguine someone to write my business plan? Evaluate and analyze the data - In this step the researcher makes use of varied methods to analyze qualitative as well as quantitative data. Case studies are in-depth investigations of a single person, group, event or community. data collected from a case study method. It is the blueprint of the procedure which contains the tools employed for data collection process and data analysis. The newer insights gained and the conflicting propositions that have emerged are suitably highlighted in the report. It is important to decide the tools for data collection because research is carried out in different ways and for different purposes. Data collection is defined as the procedure of collecting, measuring and analyzing accurate insights for research using standard validated techniques. A case study employs the use of qualitative analysis in gathering the data. A case study analysis proceeds on the lines of studying the situation to pose further questions for the research. The sampling is based on non-probability sampling techniques. Case study research typically includes multiple data collection techniques and data are collected from multiple sources. Intensive Study. It provides the basis for the application of ideas and extension of methods. Presentation of Results - The results are presented in a manner that allows the reader to evaluate the findings in the light of the evidence presented in the report. This evidence is stored comprehensively and systematically in a format that can be referenced and sorted easily so that converging lines of inquiry and patterns can be uncovered. Secondary Data Collection Methods . ualitative researchers typically rely on four methods for gathering information: (a) participating in the setting, (b) observing directly, (c) interviewing in depth, and (d) analyzing documents and material cul- ture. Beginning with a description of primary and secondary data, qualitative and quantitative data; each method of data collection has been described elaborately. It is used to explore a phenomenon based on the real life context. The article describes the decisions that need to be made in planning case study research and then presents examples of how case studies can be used in several performance technology applications. Examples of quantitative data collection methods include quantitative surveys, interviews, quantitative observations, and … In the statistical methods, the study is focussed on the distribution of variables while in the case study, it attempts in defining a variety of variables related to the subject of study. In general, primary or secondary data pertaining to these research questions can be used as a mode of data collection process. (CR, 2004). The research design in this particular dissertation involves the use of case study research strategy where the data is collected from the participants belonging to Sainsbury which includes the customers, employees and the managers of Sainsbury. There are two types of sampling strategies namely probability sampling and non-probability sampling. Experimental research is primarily a quantitative method. In most qualitative analysis, primary information is gathered mostly in the form of in depth interviews or semi-structured interviews. The research design encompasses the kind of research strategy employed for the conduct of research upon which the data collection methods and the sample size and techniques are based. The semi-structured interviews are conducted with three managers, three customers and three part-time international service employees in order to collect the required information so as to present them as findings. The data is categorized, tabulated and cross checked to address the initial propositions or purpose of the study. No Sampling.

Determine When to Use Case Studies The power, observation has been summed by W.L. Case studies are a form of inquiry that does not depend solely on ethnographic or participant observer data. The interviews are useful as they allow probing questions for further information. Some involve directly asking customers for information, some involve monitoring your interactions with customers and others involve observing customers’ behaviors. It refers to gathering information about a particular individual or a group in order to gain a holistic view about the subject of study .A case study approach is a holistic approach to observe the situation and gather valuable insights from the participants in the situation to explore phenomena. Case study method has the strengths and weaknesses of both forms of inquiry. The data collection process revolves around these research questions taking the case of Sainsbury in this study.
