Using Heidegger\u27s philosophy, the author of this study attempts to demonstrate how to conduct an effective interpretive phenomenological investigation. Heideggerian phenomenologists are distinguished by their ability to see the problem of identity; their ability to recognize ontology\u27s inadequacies; and their ability to interpret the subject matter through historical critiques. Prior knowledge and data analysis processes are also discussed in the study. Validity and creditability concerns are also addressed. To recapitulate, this work proposes a five-step approach for using Heideggerian phenomenological inquiry in social science and policymaking research, where researchers are confronted with a wide range of existing and alternative worldviews
