ISO/IEC 29155-4:2016提供了收集和维护信息技术（IT）项目数据的一般要求和指南，以及在“IT项目绩效基准框架”的基准测试活动中提供基准测试存储库的一般要求和指南，具体规定如下: a） 数据元定义的要求和指南； b） 基准框架内数据收集和维护流程的要求和指南； c） 维护基准测试存储库产品和发布的基准的要求和指南。 ISO/IEC 29155-4:2016主要关注三大活动，即“维护存储库”、“提交IT项目数据”和“测量IT项目”活动。 ISO/IEC 29155-4:2016旨在供IT项目绩效基准（e。 g、 基准测试用户、基准测试提供商、基准测试服务提供商和IT项目团队）。 注:以下是如何使用本文件的示例: -由基准测试提供商定义数据元素，收集和维护IT项目数据，并提供基准测试存储库产品或发布的基准测试； -由基准测试分析师使用基准测试存储库产品和/或基准执行基准测试实例； -由基准测试服务提供商，利用基准测试存储库产品和/或基准提供基准测试服务； -由IT服务提供商定义要测量和/或提交给存储库所有者的数据元素。 规定基准测试存储库的一组特定数据元素定义、格式或内容超出了本文件的范围。

ISO/IEC 29155-4:2016 provides general requirements and guidance for collecting and maintaining data of information technology (IT) projects and for delivering the benchmarking repository within benchmarking activities of "the IT project performance benchmarking framework" by prescribing the following: a) requirements and guidance for data element definitions; b) requirements and guidance for the data collection and maintenance processes within the benchmarking framework; c) requirements and guidance for maintaining benchmarking repository product and issued benchmarks. ISO/IEC 29155-4:2016 mainly focuses on three major activities, which are "maintain repository", "submit IT project data", and "measure IT project" activities. ISO/IEC 29155-4:2016 is intended for use by stakeholder(s) of IT project performance benchmarking (e.g. benchmarking user, benchmark provider, benchmarking service provider, and IT project team). NOTE The following are examples of how this document can be used: - by a benchmark provider, to define data elements, collect and maintain IT project data, and provide benchmarking repository product or issued benchmarks; - by a benchmarking analyst, to use benchmarking repository product and/or benchmarks for executing an instance of benchmarking; - by a benchmarking service provider, to utilize benchmarking repository product and/or benchmarks for providing benchmarking services; - by an IT service provider, to define data elements to be measured and/or to be submitted to repository owner. It is out of the scope of this document to prescribe a particular set of data element definitions, formats or contents of the benchmarking repository.
