The DevOps-approach becomes more and more important because of the success of agile software development in conjunction with the continuously changing reality. It aims at unifying development and operations. A common team is responsible for both domains. Additionally, there are approaches like Continuous Software Engineering with the intention to unify business administration (Biz) and development. Even tool chains for BizDevOps are possible. The paper discusses aspects of BizDev and BizDevOps using a subject-oriented approach for supporting aspects of HCD. The focus lies on modeling user activities and business processes. Additionally, the role of domain-specific textual languages is discussed. Most important is the fact that methods from HCI like task modeling or storytelling can support BizDev and BizDevOps.
