In most cases, systematic and scoping reviews are conducted by a team of people with different areas of expertise.

One person should be identified as the project lead. This is usually the principal investigator / subject expert. This person should be well versed in systematic/scoping review methodology.

Other team members usually include:

• Subject expert(s) - have expertise in the topic being researched and familiarity with the literature (key terminology, journals, authors, etc.)
• Librarian - develops the search strategy in consultation with other team members; runs searches; provides citations for screening; contributes to methods
• Statistician - has expertise in pooling the results of quantitative studies for meta-analysis (a statistician is not normally a member of a scoping review team)
• Screeners - may or may not be subject experts; often a role for students

Cochrane review teams are encouraged to include consumers and clinicians representing different regions and settings.
