WGITA also involves Regions and external stakeholders in their work. AFROSAI-E and ISACA are observers of WGITA and are involved in various projects of WGITA.

WGITA coordinates with Regional Working Groups as they provide members with opportunity of professional and technical cooperation on regional bodies. WGITA also works closely with INTOSAI Development Initiative (IDI), the training arm of INTOSAI, to coordinate its activities and prevent duplication of efforts. WGITA in collaboration with the INTOSAI Development Initiative (IDI) has developed an IT Audit Handbook. This IT Handbook is a very useful resource for the entire INTOSAI community in conducting IT Audits and in building capacity in this area.
