Tóm tắt	Multiple case-based classic grounded theory (CGT) extends Glaser and Strauss's original inductive framework by grounding theory development simultaneously across two or more purposefully selected cases. Rather than studying a single site or participant group, the researcher treats each case as a distinct analytic unit while using the constant comparative method to draw cross-case theoretical insights. The goal is the same as in all classic GT: emergence of a substantive theory that explains the main concern of participants — but the multi-case structure broadens the conceptual base and supports more robust theoretical abstraction.	The Constant Comparative Method (CCM) is a systematic qualitative analysis procedure in which every newly coded incident is immediately compared with all previously coded incidents in the same category. Introduced by Glaser and Strauss in their 1967 grounded theory framework, CCM drives theory development by cycling continuously between data collection and analysis, progressively refining categories until theoretical saturation is reached. Though closely associated with grounded theory, the method has been widely adopted as a stand-alone analytic strategy across qualitative traditions.
