Final answer:
The descriptor that would NOT typically be used to describe a project team member is (D) 'Adaptable to a unique but temporary purpose' because it suggests a lack of alignment with the project's intrinsic goals.
Step-by-step explanation:
The student has asked which of the following would NOT be used to describe a project team member. The potential descriptors are: (A) Motivated to use common skills to achieve a common outcome, (B) Internal employees and third-party experts, (C) Highly skilled individuals with a diverse background, and (D) Adaptable to a unique but temporary purpose. To answer this, it is helpful to understand the typical characteristics of project team members in a business context.
Project team members are typically characterized by a shared motivation (A) and diverse skill sets (C), which help in tackling complex tasks. They can be composed of both internal and third-party experts (B), bringing a mix of perspectives and expertise to the project. Being adaptable is certainly a valuable trait for project team members, as it allows them to respond to the changing needs of a project. However, the motivation here is generally aligned with the interest and goals of the project, unlike the individual described in (D) who takes a job out of necessity rather than interest. Therefore, option (D) "Adaptable to a unique but temporary purpose" would NOT typically be used to describe a project team member because it suggests a lack of intrinsic interest in the project's goals.
