   • ADeploy directly to production from the developer's machine to speed up the release process.
   • BSet up a continuous integration server that automatically builds and runs unit tests on every code commit.
   • CCreate a detailed release checklist that must be manually completed before each deployment.
   • DIncrease the frequency of manual builds on the developer's machine to ensure code compiles.

   • AKeep the CAB approval process but make it faster by holding daily meetings.
   • BAllow developers to deploy directly to production without any oversight.
   • CDeploy to production only once a week to satisfy the CAB process.
