Tailoring of Project-Specific Product Assurance Requirements

Catalog of Product Assurance Requirements

Under our direction and in close cooperation with experts of the German Space Industry, a catalog of product assurance requirements has been drawn up providing the core from which project-specific product assurance requirements can be prepared and tailored to the specific needs.

The document specifies product assurance requirements with regard to the following fields:

• product assurance management
• quality assurance and verification
• reliability, maintainability, availability
• safety
• EEE-parts and provision
• materials, mechanical parts and processes
• software quality assurance
• ground support equipment
• mission performance.
  

Expert System Tailoring Tool QMExpert

The software (QMExpert) as developed by us for the tailoring of project-specific product assurance requirements is based on a knowledge that covers the experience of industry and agencies in national and international spaceflight; QMExpert follows standards of international spaceflight and the existing standards of the European Cooperation for Space Standardization (ECSS).

With QMExpert, a DP-Tool is at DLR’s disposal, which presently represents a highly-considered, top-class product in spaceflight management.

Tailoring is based upon the evaluation of tailoring criteria (project characteristics):

• type of project
• complexity
• budget
• life cycle
• risk policy.

With tailoring, the profile of requirements differs in

• in the amount of deliverables and individual procedures
• in the nature of methods to be applied
• in the extent of  contractor’s verification
• in the number of actions to be considered during design.
