From a citizen-centric perspective of a smart city, we study a number of services that large cities extend to its populace. Using service typologies from services marketing as a backdrop, and recent advances in analytical customer relationship management (CRM) as a paradigm, we identify those services that are likely to benefit most from the introduction of data analytics in their design and delivery. We generalize these observations and logical conceptions into a prescriptive process that isolates the characteristics of services that can benefit from data analytics.
