Description of 21/30399928 DC 2021

Industry and large organisations recognize the value of VSEs, i.e. enterprises, organisations (e.g. government agency, non-profit organization), projects or departments with up to 25 people, in contributing with emerging new technology that bigger organisations cannot use them as easily nor incorporate them in their solutions as fast. But often these VSEs are not ready to comply with the requirements for space projects. But, Space-VSEs could demonstrate the quality of their processes in a stepwise approach to participate to space projects.

This document establishes a common framework for software lifecycle processes for Space-VSEs developing or maintaining software for the space domain.

This document is targeted at acquirers of space systems and software and services and for small suppliers, developers, managers, and quality assurance managers of software in the space domain.

This document provides the specifications of 3 space profiles for VSEs through a set of development and organisational processes.

This document adds specifications to the software Basic profile specifications, defined in ISO/IEC 29110-4-1, and to the software Organisational Management profile specifications, defined in ISO/IEC 29110-4-2.

This document provides a process assessment model and a maturity model for the process quality growth demonstration of Space-VSEs.

The document may also be used by a single party through a self-imposed set of processes.

This document does not:

• detail the processes in terms of methods or procedures required to meet the requirements and outcomes of a process.

• detail documentation in terms of name, format, explicit content and recording media.

• prescribe a specific system or software life cycle model, development methodology, model or technique.

The users of this document select the processes to be deployed and map them to the specific project lifecycle model. The parties are also responsible for selecting and applying the software development methods and for performing the activities and tasks suitable for the software project.

This document is not intended to be in conflict with any organization's policies, procedures, and standards or with any national laws and regulations. Any such conflict should be resolved before using this document.

The requirements in this document are contained in Clauses 7, 8 and 9 in an incremental maturity process profiles definition. This document provides requirements for a number of processes suitable for usage during the lifecycle of a software developed or maintained by a VSE in the space domain. It is recognized that a specific project may not need to use all the processes provided by this document. Therefore, the implementation of this document typically involves selecting a set of processes suitable to the VSE.

This document provides the normative and informative links to the subsets of ISO/IEC IEEE 12207 and ISO/IEC IEEE 15289 selected for this standard.

This document is also applicable to the development or maintenance of software of the lowest level of software criticality categories C or D as defined in the European Cooperation for Space Standardization (ECSS) standard ECSS-Q-ST-80C rev1. Annex C of this document provides the processes of the Space-VSE profile according to the standards of the European Cooperation for Space Standardization (ECSS) and the ISO/IEC 29110 series. Annex C also provides the definition of the safety criticality categories of software according to ECSS standards.

Space-VSEs could use the guidelines provided in the ISO/IEC TR 29110-7-1 to implement the processes listed in this document.
