A systematic review team is essential to producing a sound systematic review. Team members work together in order to define their research question, develop a comprehensive search strategy aimed at mitigating bias and an effective workflow, and adhere to appropriate methodology, professional standards, and review guidelines. Teams may be as small as two people (although not recommended) or larger. Team members may have more than one role depending on their expertise and varying degrees of activity throughout each stage of the project. Ideally a team would include:
Librarians or Informationists, as they are sometimes referred to in some institutions, are essential to any systematic review team for their expertise in navigating the information landscape.
