联邦政府和行业已经转向使用集成过程团队（IPT）的并行采办和开发过程。信息技术（IT）的进步使集成数据环境（IDE）能够及时、准确、跨功能地访问数据，从而支持这些过程。自1994年收购改革以来，数据管理（DM）实践已从一套规范性的标准和程序发展为在原则中使用指南- 基于标准——ANSI/EIA 859。GEIA手册859为ANSI/EIA 859提供了实施指南，讨论了该标准的原则、工具、示例和案例研究的应用。859手册是根据数据管理的生命周期组织的，涵盖了从RFP前阶段到记录处理的活动。它还提供了适用于生命周期多个阶段的主题的附件，如数据保护、持续改进和知识管理。

The federal government and industry have moved to concurrent acquisition and development processes using integrated process teams (IPTs). These processes are supported by timely, accurate, cross functional access to data within an integrated data environment (IDE) enabled by advances in information technology (IT). Since the advent of acquisition reform in 1994, Data Management (DM) practices have evolved from being directed by a prescriptive set of standards and procedures to use of the guidance in a principles-based standard -- ANSI/EIA 859.GEIA Handbook 859 provides implementation guidance for ANSI/EIA 859, with discussions of applications of the standard's principles, tools, examples, and case studies. Handbook 859 is organized according to the lifecycle of data management and covers activities from the pre-RFP stage through records disposition. It also provides annexes on topics which apply at multiple stages in the lifecycle, such as protection of data, continuous improvement and knowledge management.
