Requirements Mapping Matrix Templates for NPR 7150.2D
*** The term Requirements Mapping Matrix replaced Compliance Matrix starting with NPR 7150.2C. ***
The Requirements Mapping Matrix templates were updated on 5/16/2025 to include electronic signatures and are provided in two formats, Excel and PDF. The Excel format uses Office 365 electronic signatures which only work with Excel for Windows. Furthermore, signing an O365 signature places the workbook in protected mode and will invalidate signed signatures if any change is made other than further signing. The PDF format works on all platforms supported by Adobe Acrobat Reader. The PDF format, however, is limited to fixed-sized fields. You can add more text than the field size. That text will word wrap and scrollbars will appear when the field is selected. Upon exiting the field, only the initial lines to the end of the field will be visible.

- Requirements Mapping Matrix for Class D ( Excel | PDF )
- Requirements Mapping Matrix for Class E ( Excel | PDF )
[Note 1: The Requirements Mapping Matrices now add the Center CIO Tailoring Authority as a signatory for tailoring. Center CIO approval is needed only if the project tailors cybersecurity requirements whose technical authority (column C) contains the text ‘CIO TA’. The individual(s) designated by the Center CIO as the Center CIO Tailoring Authority is listed on the home page.]
[Note 2: As an alternative to electronic signatures, you can use the Microsoft Approvals app. This app is available in Microsoft Teams. A quick introduction to Microsoft Approvals is available as a digital transformation tip, TxTip: Microsoft Approvals.]

This link contains examples, guidance, and tools for earlier revisions of NPR 7150.2 and LPR 7150.2. These items may still provide some value to helping projects adhere to the Agency and Center software engineering requirements. However, they are now incomplete with respect to recent revisions of governing documents and they reference obsolete governing documents (including cancelled center procedures for software engineering).
