Bitner, Fisk and Brown (1993) suggest that the major output from the services marketing literature up to 1980 was the delineation of four services characteristics: intangibility, inseparability, heterogeneity and perishability. These characteristics underpinned the case for services marketing and made services a field of marketing that was distinct from the marketing of products.
The literature highlights intangibility as one of the key characteristics of services. Regan (1963) introduced the idea of services being “activities, benefits or satisfactions which are offered for sale, or are provided in connection with the sale of goods”. The degree of intangibility has been proposed as a means of distinguishing between products and services (Levitt, 1981). Darby and Karni (1973) and Zeithaml (1981) highlight the fact that the degree of tangibility has implications for the ease with which consumers can evaluate services and products. Other studies suggest that intangibility cannot be used to distinguish clearly between all products and services. Bowen (1990) and Wyckham, Fitzroy and Mandry (1975) suggest that the intangible-tangible concept is difficult for people to grasp. Bowen (1990) provides empirical evidence to support this view. Onkvisit and Shaw (1991) feel that the importance of intangibility is over-emphasised. They believe that the service provider’s offer is their “productive capacity” and not the (in) tangible nature of the offer
Inseparability of Services
Inseparability is taken to reflect the simultaneous delivery and consumption of services (Regan 1963; Wyckham et al 1975; Donnelly 1976; Grönroos 1978; Zeithaml 1981; Carman and Langeard 1980; Zeithaml et al 1985; Bowen 1990 and Onkvisit and Shaw 1991) and it is believed to enable consumers to affect or shape the performance and quality of the service (Grönroos, 1978; Zeithaml, 1981).
Heterogeneity of Services
Heterogeneity reflects the
