phase 1
First project segment
Phase 1 is the first stage of a multi-stage process, especially in clinical trials where new drugs are tested on a small group of people for safety before broader efficacy studies.
The term appears in any sequential framework: We're still in phase 1 of the renovation.
Phase 1 establishes baseline conditions before proceeding.
