Which of the following roles is NOT typically part of a software development team?

In the context of a software development team, roles are clearly defined to ensure that the project progresses efficiently and effectively. A Business Analyst plays a crucial role by bridging the gap between stakeholders and the development team, ensuring that the requirements are well understood and met. The Project Manager oversees the project execution, coordinating between team members, managing timelines, and ensuring that the project stays within scope and budget. Testers are essential as they are responsible for validating the software's functionality, identifying bugs, and ensuring that the final product meets the quality standards.

In contrast, a Mechanic typically refers to someone who repairs machinery or engines, which is unrelated to software development. This role does not contribute to aspects of software design, development, project management, or testing. Therefore, it does not fit within the structure of a software development team, making it the outlier among the provided options.
