A build process management system can acquire data pertaining to a software build process that is currently being executed by an automated software build system. The software build process can include executable process steps, metadata, and/or environmental parameter values. An executable process step can utilize a build artifact, representing an electronic document that supports the software build process. The acquired data can then be synthesized into an immutable baseline build process and associated baseline artifact library. The baseline artifact library can store copies of the build artifacts. The immutable baseline build process can include baseline objects that represent data values and dependencies indicated in the software build process. In response to a user-specified command, an operation can be performed upon the baseline build process and associated baseline artifact library.
