Information-gathering through Observation

• The researcher may ask to examine the arch setting of her company's software adoption processes as part of the case study's investigation. Case study researchers may be able to glean more objective information on research issues from observations of the setting than through interviews, which depend on people's subjective perceptions and memories of events. However, competence and perseverance are required to perform significant observations.
• When gathering data via observation, the researcher has to keep in mind these five things. In order to shed light on potential responses to the study questions, it is crucial that the researcher first determine the most essential component that must be examined. A scheduling-curious administrator, for instance, would compare the frequency and kind of disciplinary referrals made before and after using the strategy at many schools. If a teacher is interested in the causes of student dropout, she can opt to compare the performance of her students in classes where she uses various methods of education. A nurse who is curious in his hospital's hiring processes can observe the human resources officer conducting interviews with potential employees. A technologist looking into her company's software adoption practices can seek to sit in on meetings where decisions are made concerning the capabilities of computer software.
• Second, an observation guide, which is a checklist of points to be covered during an observation, should be made by the case study researcher. Common items in this list are 
• Before releasing a final report, a case study researcher should verify the study's results once they have been obtained, summarized, and presented. One's results may be verified in a number of ways. A case study researcher should try to use as many of these methods as they can. 
• One of the most effective ways to verify the accuracy of a report is to show its contents to the people who were the focus of the research. The researcher has an ethical responsibility to debrief study participants, and this action furthers that goal. Those being examined are polled for their thoughts on the study's credibility, taking into account the information the participants themselves gave.
• Reviewing the report with other case study researchers who are acquainted with the aims and methods of case study research is another option. They should critically examine the study's methods and results in order to spot inconsistencies that might cast doubt on the study's validity.
• In a similar vein, it might be useful to have subject-matter specialists review the completed report. A teacher investigating student dropout rates at her school may, for instance, submit her report to the scrutiny of colleagues outside the context of the case study to ensure its correctness, clarity, and significance.
•  A fourth method is for the researcher to explain any inherent biases and any steps taken to lessen the impact of such biases. It is less likely that a researcher would be accused of fabricating results if they admit to having biases and explain how they were managed throughout the study process and analysis.
• The use of various sources of evidence (also known as "triangulation") is a fifth method for corroborating results. Evidence gathered via interviews, observations, and documents is more persuasive than evidence gathered through just one or two of these methods. Researchers that use case studies often draw parallels between their own results and those of other scholars.
• Before releasing their results for wider evaluation and feedback, case study researchers double-check and triple-check their work.They do this by disseminating the findings of their research to other researchers and professionals in the field. In addition, they admit to having their own preconceived notions about the subject matter and describe the measures they took to keep them from influencing the results of the study.They use several techniques to determine results. To validate and bolster trust in what was revealed as a consequence of study, case study researchers often tie their results to the work of others, much as researchers presenting findings from studies using other techniques do.
