You are the program manager for a new software development program. One of the developers has been adding extra fields for information in the software that was not part of the original program scope.

Preventive action refers to proactive steps taken to avoid future performance deviations, not to the unauthorized addition of work outside scope.

Corrective action refers to steps taken to bring future performance back in alignment with the plan, not the introduction of unapproved out-of-scope work.

Gold plating describes adding extra quality or features beyond what was requested; the formal program management classification for work added outside the approved scope baseline is a scope change requiring change control.

When a developer adds features that were not part of the approved program scope baseline, this constitutes an unauthorized program scope change - work was added without following the integrated change control process. Any addition of deliverables or work outside the approved scope must be formally evaluated and approved through change control before execution begins.
