Companies producing software-intensive products do not only offer products to customers but Product Service Systems (PSS), a combination of the products and services that address customers’ needs. Further, product-related services are key in ensuring customer satisfaction as the service organization represents the company’s interface toward its customers, who operate and use the products. Therefore, while DevOps has been widely adopted in companies developing web-based applications aiming to streamline the Development and Operations activities, the projecting of DevOps as applied in web-based applications to PSS is difficult without considering the role of services. Therefore, based on a two years participant observation case study conducted at a multinational telecommunications systems provider, we propose a new and novel approach called Development-Services-Operations (DevServOps) which incorporates services as a key player facilitating an end-to-end software flow toward customers in one direction and feedback toward developers in the other direction.
