This ECSS Standard is part of a set of ECSS Standards belonging to the management branch.
In order to create the reference system for project management necessary for implementation of a project and ensure consistency, the project is broken down in a unique, orderly and exhaustive manner, to allow unambiguous identification of the associated products and models, as well as the tasks and resources necessary.
This Standard defines the principles to be respected for setting up, using and adapting the breakdown structures and implementing them in a project.
When viewed from the perspective of a specific project context, the requirements defined in this Standard should be tailored to match the genuine requirements of a particular profile and circumstances of a project.
NOTE: Tailoring is a process by which individual requirements of specifications, standards and related documents are evaluated and made applicable to a specific project by selection, and in some exceptional cases, modification of existing or addition of new requirements.
