Preliminary stage (PWI)
This comprises projects envisaged for the future but not yet ripe for immediate development, or preliminary work, such as better definition of a project for new work, data collection or round-robin tests necessary to develop standards, which is not part of the standardization process.
The preliminary stage is applied for work items where no target dates can be established. This stage can be used for the elaboration of a new work item proposal and the development of an initial draft. These work items are subject to approval in accordance with the normal procedures before progressing to the preparatory stage.
