-
Support testing and acceptance activities by ensuring requirements and acceptance criteria are clear and measurable.
-
Help identify opportunities for process improvement, service improvement and service design.
-
Operate effectively within a small team, taking ownership of tasks and proactively identifying what needs to be done without requiring significant direction.
