DevOps has become a widely adopted approach in the software industry, especially among companies developing web-based applications. The main focus of DevOps is to address social and technical bottlenecks along the software flow, from the developers' code changes to delivering these changes to the production environments used by customers. However, DevOps does not consider the software flow's content, e.g., new features, bug fixes, or security patches, and the customer value of each content. In addition, DevOps assumes that a streamlined software flow leads to a continuous value flow, as customers use the new software and extract value-adding content intuitively. However, in a Software-intensive System of Systems (SiSoS), customers need to understand the content of the software flow to validate, test, and adopt their operation procedures before using the new software. Thus, while DevOps has been extensively studied in the context of web-based applications, its adoption in SiSoS is a relatively unexplored area. Therefore, we conducted a case study at a multinational telecommunications provider focusing on 5G systems. Our findings reveal that DevOps has three sub-flows: legacy, feature, and solution. Each sub-flow has distinct content and customer value, requiring a unique approach to extracting it. Our findings highlight the importance of understanding the software flow's content and how each content's value can be extracted when adopting DevOps in SiSoS.
