Due to the growing number of providers and technological change, expectations for companies and their offered products are rising, forming a focal point in competitive success.

The increasing intensity of competition due to globalization and the resulting dissolution of market entry barriers leads to competing products and services appearing identical and being perceived as interchangeable by customers.
