From my experience reviewing FinTech frameworks, complexity is best measured through composite indicators rather than single metrics. I have seen studies combine technological layers, regulatory exposure, integration requirements, and user interfaces to rank systems comparatively. I would recommend developing a weighted index tailored to your research objective. This approach allows complexity to be treated as a continuum, making it more analytically useful than binary classifications.
