At its 24^th session (2017) the IODE Committee approved the Report of the Inter-sessional Working Group to Propose a Re-structuring of IODE which recommended revising the current structure, projects and activities of IODE and decided that the relation between projects (e.g. data flow) should be better communicated within the IODE community but also to the user communities. The 27^th session of the IODE Committee (2023) approved the designation of IODE activities as Programme Components, Programme Activities and Projects.

Existing and new Programme Components, Programme Activities and Projects need to ensure that they meet IODE strategic goals and objectives. These procedures apply to both existing and new projects and activities.

This revised edition includes changes requested by the IODE Management Group to address the following issues: (i) all Programme Components, Programme Activities and Projects should develop work plans that have clear performance indicators and measurable deliverables, and (ii) the reporting template should align with the work plan and which would allow for more straightforward evaluation by the IODE Management Group.
