Service design is transformative when it has a measurable, even optimizing, positive affect on human well-being. Any prospect for such felicitous outcomes, however, requires accurate assessment or measurement of well-being in and for target populations. Such assessment raises two immediate issues: conceptualization (How should well-being be conceptually operationalized?) and measurement (Given an operationalization of well-being, how can it be measured?). We begin to explore and address both questions in this paper by reviewing existing conceptualizations of well-being and then by describing the relevance of well-being measurement (and it methodologies) which are presently available
