Skinner (1969) identified four main competitive priorities. These are cost, quality, delivery, and flexibility.
1. Cost: Competing on cost means delivering a service as a product at the lowest cost when compared with competitors’ services or products (Krajewski, Ritzman, & Malhotra, 2015, p. 32; Reid & Sanders, 2012, p. 37).
2. Quality: As a precondition of competitiveness in global markets, quality can be generally defined as satisfying the requirements of the customers with the launched product, conformance to specifications and being free of error (Li, 2000; Forker et al., 1996; Krajewski & Ritzman, 2005; Akal, 1998).
3. Time: The ability to provide high-quality products in a short time as possible. Time is one of the most important competitive priorities today since today’s customers can’t wait.
4. Flexibility: Flexibility is defined as adapting to the changes occurred in the preferences of the customers easily and quickly (Amoako-Gyompah, 2003). There are two dimensions of flexibility. One is product flexibility which is defined as the ability to offer a wide variety of goods or services and customization of them to the requirements of the customers. Another one is called volume flexibility which means the ability to change the amount of production according to demand changes.
