Data are the various forms of documentation required to support a program in all of its areas (e.g., administration, engineering, configuration management, financial, logistics, quality, safety, manufacturing, and procurement). The data may take any form (e.g., reports, manuals, notebooks, charts, drawings, specifications, files, or correspondence). The data may exist in any medium (e.g., printed or drawn on various materials, photographs, electronic, or multimedia). Data may be deliverable (e.g., items identified by a program’s contract data requirements) or data may be nondeliverable (e.g., informal data, trade studies and analyses, internal meeting minutes, internal design review documentation, lessons learned, and action items). Distribution may take many forms, including electronic transmission.
The data requirements for the project should be established for both the data items to be created and their content and form, based on a common or standard set of data requirements. Uniform content and format requirements for data items facilitate understanding of data content and help with consistent management of the data resources.
The reason for collecting each document should be clear. This task includes the analysis and verification of project deliverables and nondeliverables, contract and noncontract data requirements, and customer-supplied data. Often, data is collected with no clear understanding of how it will be used. Data is costly and should be collected only when needed.
