1.0 INTRODUCTION
1.1 PURPOSE
This document establishes programmatic hardware and software safety and product assurance (reliability, maintainability, and quality assurance) requirements and related implementation processes, agreed between NASA and Agenzia Spaziale Italiana (ASI) for the design, development, production, test, and operation of International Space Station (ISS).
1.2 SCOPE
These safety and product assurance requirements are applicable to all flight equipment, and certain Ground Support Equipment (GSE) (as specified herein) and related software supplied for ISS by ASI. The programmatic application of the requirements of this document shall be tailored, as appropriate, by ASI consistent with overall program objectives.
1.3 MANAGEMENT APPROACH
Management of safety and product assurance shall include the following:
| A. | Defining the major hardware and software safety and product assurance tasks and assuring that they are performed as integral parts of all phases of the program |
| B. | Evaluating the safety, reliability, maintainability, and quality of hardware, software, and operations through analyses, tests, reviews, and assessments |
| C. | Providing timely status reporting through periodic project reviews and as a part of overall project status reports |
| D. | Ensuring compatible safety and product assurance requirements among manufacturing, test, launch, and ground operations sites |
The ASI Safety and Product Assurance Office shall prepare, implement and maintain a Safety and Product Assurance (S&PA) Program Plan which defines the tasks and products of the Safety, Reliability, Maintainability and Quality Assurance (SRM&QA) activities and organizational responsibilities for task implementation. The plan will provide visibility of SRM&QA activities to be accomplished during the life of the ISS. Safety and product assurance management shall have direct unimpeded access to the management level having full project responsibility. The ASI S&PA Program Plan will be exchanged in accordance with SSP 50125, NASA/ASI Data Exchange Agreement, Lists and Schedules.
E. NASA Space Station Program shall assure that results of SRM&QA analyses are integrated into ISS assessment activities, so that the effects of Mini-Pressurized Logistics Module (MPLM) design options can be assessed.
1.4 RELATION TO OTHER REQUIREMENTS
1.4.1 PROGRAM REQUIREMENTS
The safety and product assurance requirements set forth in this document shall take precedence in cases of conflict with requirements contained in subtier documents. The safety and product assurance design requirements are contained in SSP 41164, Italian Mini-Pressurized Logistics Segment Specification.
1.4.2 GSE HARDWARE AND SOFTWARE
S&PA analyses for GSE hardware and software procured by ASI from existing programs need not be performed again if ASI has determined the use of the GSE is within the scope of the original analysis and meets current program requirements. All Critical Items and accepted risk hazards identified in these analyses must be baselined by the ISS.
1.5 MOTIVATION
A product-oriented motivational (awareness) activity shall be implemented by the NASA Centers (and their contractors) and, as appropriate, by ASI and its contractor as an integral part of and making maximum use of existing motivational activities. The objective of this activity shall be the prevention of human error by instilling in personnel an awareness of their personal responsibility for ISS success.
1.6 INDEPENDENT EVALUATIONS FOR NASA OR THE INTERNATIONAL PARTNERS
NASA and the International Partners reserve the right to appoint independent representatives to assist in safety and product assurance evaluation activities. These representatives will provide technical support to the applicable parent organization and determine effectiveness of and recommend improvements for safety and product assurance activities.
1.7 DATA REQUIREMENT DESCRIPTIONS
All S&PA exchange data between NASA and ASI shall be identified in this document (refer to Table 1), and details and submittal requirements of the exchange data will be specified in SSP 50125.
1.8 SAFETY AND PRODUCT ASSURANCE DATABASE
S&PA data bases shall be established. The data transfer format will be defined in SSP 50125.
1.9 MILESTONE REVIEWS
Safety and product assurance activities shall include supporting internal and supplier design reviews, and NASA and International Partner design and readiness reviews. Participation in milestone reviews shall assure that S&PA requirements are adequately considered.
ASI shall support the implementation of the ISS Safety Review Process as it is described in SSP 30599. The Safety Review Panel (SRP) assesses the MPLM element design for compliance with the safety requirements established in the SSP 50021.
Space Station Program major program milestone review safety assessment reports shall be prepared and submitted to the ISS Safety and Mission Assurance (S&MA) Program Office, within a defined period of time following the Space Station Program major program milestone reviews, as specified by the Director, International Space Station Alpha.
1.10 CERTIFICATION
S&PA shall ensure that products requiring certification meet the requirements contained in SSP 50108, Certificate of Flight Readiness Process Document.
1.11 DELEGATION OF AUTHORITY
This document is controlled, through approval signatures, by the NASA Space Station Program Manager and the ASI MPLM Program Manager. Either Program Manager can propose a change to this document by initiating a letter to the other Program Manager. Following a change proposal letter, both Program Managers will authorize the appropriate activity to discuss the proposed change. Changes to this document are approved by NASA and ASI Program Managers at either Space Station Control Boards (SSCBs) involving ASI participation or at NASA/ASI Joint Program Reviews. All changes to this document require the approval of both the NASA and ASI Program Managers. Following initial joint approval, NASA maintains this document, including the incorporation of approved changes.
