The core service refers to all the components of a
service (Sureshchander, Rajendran, & Anantharaman,
2002) and represents the basic product or service being
offered by the service provider. According to Brogowicz,
Delene, and Lyth (1990), core service represents the
“what” of a service offering. Marketing scholars encourage
firms to deliberately adopt strategies that emphasize
the core benefits of their services to existing and
potential customers (Al-Eisa & Alhemoud, 2009). This
helps customers to form realistic expectations about
the services and their role in the coproduction process
(Garry, 2008).
