A person performing this role can have specialized skills in a particular technical area but should also have a broad
understanding of all of the technologies involved to be able to work with other technical team members. In small,
agile teams, this role is often shared among several team members who also perform other roles.
It is common for a person to act as both legacy expert and Tool expert, taking on the responsibilities of both roles.
It is possible for more than one person to act as the tool expert for a single assessment project, either by dividing
responsibilities between themselves or by performing tasks together, as in a pair-assessment approach to cover complex
assessments.
