SaaS provides many advantages for customers and the adoption continues to expand within organizations. There are some key factors to foster the adoption of a subscription model by its customers. Cost competitiveness is a major factor for customers as they expect to have lower initial costs without upfront fees compared to the traditional licensing. To facilitate the adoption, it’s also important to provide the scalability and flexibility of services needed by users (add/reduce the number of users, extend capabilities…). The quick set-up of services in a shortened time could be a critical factor for some users and should be considered as an important dimension to facilitate the adoption.
