In the context of business analysis, who or what is an actor?

In business analysis, the term "actor" refers to any human, device, or system that interacts with a particular solution. This broad definition encompasses a variety of participants in a system or process, highlighting the diverse interactions that can occur.

Understanding the concept of an actor is crucial because it helps business analysts identify various external entities that can influence or utilize a solution. By defining the roles and interactions of these actors, analysts can gather requirements more effectively and ensure that the solution meets the needs of all parties involved. For example, actors could include end-users directly engaging with the software, external systems that send or receive data, or even other stakeholders involved in the workflows.

The other options, while relevant to the broader context of business analysis, do not capture the full meaning of an actor. Roles filled by team members relate to internal staffing and responsibilities but do not encompass the range of entities involved. A stakeholder in the project typically refers to individuals or groups with an interest or investment in the project's outcomes and doesn't specifically denote interaction with the solution itself. Lastly, referring to a type of software used in development misses the essence of interaction, as actors are defined by their interaction rather than their nature as software applications.
