CA5: Packaging

  • Minimum standard - SML3

  • Expected standard - SML4

  • Excellent standard - SML5

SML1 - Initial usability: Only source code or executable files are available; i.e. there is no packaging to create a package or container. There is no, or incomplete, configuration documentation and no deployment information is available. Even an experienced user may have difficulties deploying the software.

SML2 - Use is feasible: Software includes packaging to create a package or container. Detailed configuration instructions are available and deployment is possible for an experienced user.

SML3 - Use is possible by most users: The packaged bundle or the containerised software is easily configurable for different contexts, as the locations of resources (files, directories, URLs) are configurable. All configuration-specific information is centralised.

SML4 - Software is usable: Configuration information is available and can be scripted to deploy the packaged/containerised software from the command line. Versions of deployed software can be upgraded/rolled back automatically. Data and/or index files can be restored automatically.

SML5 - Demonstrable usability: A Continuous Integration server job (or equivalent) is available to deploy the packaged/containerised software. Administrators are notified if deployment fails. Versions of deployed software can be upgraded/rolled back from a Continuous Integration server job (or equivalent). Data and/or index files can be restored from a Continuous Integration server job (or equivalent).
