What is Cumulative Case Study

Case studies have been widely used across a number of disciplines including health, business management, education, law, and in the social sciences. The purpose of this chapter is to define and differentiate types of case studies, discuss the pros and cons of single versus multiple case studies, explore the necessary processes for engaging in this technique, and explain how data is collected and analyzed. A variety of data gathering methods are discussed to identify the challenges to be confronted, and the skills necessary to engage in this methodology. The author identifies how qualitative and quantitative techniques are used in case study analysis. Methods to maximize researcher objectivity, reliability and validity are examined by focusing on data collection, document management, and data analysis.
