DID DI-MGMT-82165是国防部（DoD）收集技术参数数据的系统，作为成本、软件和数据报告（CSDR）要求的一部分。由此产生的数据存储库是许多国防部资源分析工作的合同成本、软件和技术数据的主要来源；包括成本数据库开发、应用成本估算、成本研究、项目评审、备选方案分析（AoA）和生命周期成本估算。技术数据报告允许政府对技术和方案解决方案进行独立评估，数据提供了成本数据的背景，有助于建立成本估算关系。

DID DI-MGMT-82165 is the Department of Defense (DoD) system for collecting technical parameter data as part of the Cost, Software, and Data Reporting (CSDR) requirement. The resulting data repository serves as the primary source for contract cost, software, and technical data for many DoD resource analysis efforts; including cost database development, applied cost estimating, cost research, program reviews, Analysis of Alternatives (AoA), and life cycle cost estimates. The Technical Data Report allows the Government to produce independent assessments of technical and programmatic solutions, and the data provides context to the cost data that assists in developing cost estimating relationships.
