1.1应用领域
这些服务提供指南适用于非常小的实体（VSE）。VSE是指最多有25人的企业、组织、部门或项目
ISO/IEC TR 29110-5-3:2018提供了管理向客户提供的一系列服务的指南。VSE可以充当内部服务提供商（为VSE提供内部服务）或外部服务提供商（为外部客户提供商业服务）。这些生命周期过程（治理、服务控制、服务关系和服务事件）支持并增强软件和系统操作（进一步到开发和安装）的活动，以创建高效的产品和服务
ISO/IEC TR 29110-5-3:2018提供了服务交付指南。本文件在实施时将帮助和指导VSE提供有利于客户的服务。 本文件并不促进所有组织在方法上的一致性，因为具体的目标和计划是根据单个组织的需求量身定制的
本指南文件中描述的任务（以及活动和流程）通过输入/输出关系进行关联，这意味着逻辑执行顺序。过程或相关编号方案的呈现顺序仅用于识别目的，而非指示实施或执行顺序。因为每个VSE都是不同的；任务可以按照适合组织的顺序执行，同时尊重任务之间的关系
1.2目标受众
ISO/IEC TR 29110-5-3:2018旨在供VSE使用，以建立实施有效和高效服务交付的流程。本服务交付指南文件可供仅向其客户提供服务的VSE使用，也可与ISO/IEC 29110系统和/或软件管理和工程指南中的信息结合使用。

1.1 Fields of application
These Service Delivery guidelines are applicable to Very Small Entities (VSEs). A VSE is an enterprise, an organization, a department or a project having up to 25 people.
ISO/IEC TR 29110-5-3:2018 provides guidance to manage a set of services delivered to customers. The VSE can act as an internal service provider (providing services internal to the VSE) or as an external service provider (providing services commercially to external customers). These lifecycle processes (Governance, Service Control, Service Relationship and Service Incident) support and enhance the activities of software and system operations (further to development and installation) to create effective and efficient products and services.
ISO/IEC TR 29110-5-3:2018 provides guidance for Service Delivery. This document, when implemented, will assist and guide the VSE in the delivery of services which can benefit customers. This document does not promote uniformity in approach across all organizations as specific objectives and initiatives are tailored to suit an individual organization's needs.
Tasks described in this guideline document (and therefore activities and processes) are related by input/output relationships which imply a logical execution sequence. The order of presentation of the processes or the associated numbering scheme is for identification purposes only, NOT to indicate implementation or execution order. As every VSE is different; tasks can be implemented in an order that is suitable for the organization, while respecting the relationships between tasks.
1.2 Target audience
ISO/IEC TR 29110-5-3:2018 is intended to be used by VSEs to establish processes to implement effective and efficient service delivery. This service delivery guidelines document can be used by VSEs that are offering only services to its customers or it can be combined with the information from ISO/IEC 29110 systems and/or software management and engineering guidelines.
