สรุป	Multiple case-based phenomenology combines the bounded, comparative logic of multiple case study design with the lived-experience focus of phenomenological inquiry. The researcher selects two or more distinct cases — individuals, sites, or groups — who share the same target phenomenon, conducts phenomenological analysis within each case, and then synthesises findings across cases to identify both shared essential structures and case-specific variations. The result is richer and more transferable than a single-case phenomenological study while remaining grounded in the depth that phenomenology demands.	Longitudinal phenomenology applies phenomenological inquiry across two or more time points to capture how participants' lived experience of a phenomenon changes, deepens, or transforms over time. Rooted in the phenomenological tradition of Husserl and Heidegger, it adds an explicit temporal dimension — asking not only what an experience is like, but how it evolves. It is used where a single-point interview would miss the processual, shifting nature of lived meaning.
