요약	Concurrent multiphase mixed methods design combines the structural complexity of multiphase research — spanning several distinct project phases — with concurrent (simultaneous) data collection within each phase. At each stage, quantitative and qualitative data strands are gathered and analyzed in parallel rather than sequentially, and findings are integrated across phases to address a program of interrelated research questions over time.	The exploratory sequential mixed methods design is a two-phase research framework in which a qualitative phase is conducted first to explore a poorly understood phenomenon, and the findings then inform a subsequent quantitative phase — typically to develop and test a survey instrument, measure a theory, or generalize qualitative insights to a larger population. The qualitative strand guides what is measured; the quantitative strand tests or extends those findings at scale.
