ISO 11893:2011 defines the project organization principles and requirements needed to provide satisfactory and coherent management of space projects. The general requirements for project organization are given in ISO 14300-1. It addresses the following, in particular:

1. responsibility and authority of the actors (all actors, customer, supplier),
2. interrelations between the actors (meetings, action monitoring, reporting, assessments and audits),
3. information technologies, and
4. project organization documentation.

The requirements specified herein apply to and affect the supplier and customer at all levels. ISO 11893:2011 is applicable to the customer-supplier relationship for space products to the extent agreed by both parties. It is intended to be used as a basis when establishing and negotiating customer program/project management requirements and to guide the supplier's responses. When viewed in a specific project context, the requirements defined in this International Standard should be tailored to match the specific requirements of a particular profile and circumstances of a project.
