RESEARCH METHODOLOGY

Detailed explanation-1: -Exploratory case studies explore situations in which the case (intervention for example) being evaluated has no clear or single set of outcomes. According to Yin a descriptive case aims to describe the phenomenon within the context it occurred.

Detailed explanation-2: -Within these types, a case study may take four different forms: illustrative, exploratory, cumulative, and critical.

Detailed explanation-3: -An Exploratory Case Study is used to develop an initial understanding of the program or phenomenon of interest. The focus is on discovery for the purpose of obtaining an empirically based introduction to the structure, dynamics and context of the subject of interest.

Detailed explanation-4: -The case study methodology is ideally suited to real-world, sustainable intervention development and evaluation because it can explore and examine contemporary complex phenomena, in depth, in numerous contexts and using multiple sources of data [8].
