软件和系统工程 非常小实体（Very Small Entities VSEs）生命周期配置文件 第5-6-1部分：系统工程 管理和工程指南：通用配置文件组：入门配置文件（ISO/IEC TR 29110-5-6-1:2015）

ISO/IEC 29110:2015 is applicable to Very Small Entities (VSEs). VSEs are enterprises, organizations, departments or projects having up to 25 people. The lifecycle processes described in the set of International Standards (IS) and Technical Reports (TR) are not intended to preclude or discourage their use by organizations bigger than VSEs. ISO/IEC 29110:2015 provides the management and engineering guide to the Entry Profile described in ISO/IEC 29110-4-6 through Project Management and System Definition and realization processes. This part of ISO/IEC 29110 is a standalone guide; it is not intended for a VSE to use the standardized profile to implement ISO/IEC 29110:2015. ISO/IEC 29110:2015 applies for non-critical systems development projects. The system development should fulfil the project requirements and the system description. ISO/IEC 29110:2015, a VSE can obtain benefits in the following aspects: – an agreed set of project requirements (technical part of contract) and expected products are agreed by the Acquirer; – a disciplined management process, that provides project visibility and corrective actions of project problems and deviations, is performed; – a systematic System Definition and Realization process, that satisfies Acquirer needs and ensures quality products, is followed. VSEs developing software that is part of a larger system and for standalone software products and services are encouraged to use the management and engineering guide of the Entry Profile (ISO/IEC TR 29110‑5‑1‑1).
