 Situation Analysis:

Proofing of the product manual requires 15 additional days.

This impacts the Print Product Manual (Activity F), which is a critical path activity.

 Maintaining the Availability Date:

To prevent delays in the product release (Activity H), the additional 15 days for proofing must be offset.

Reducing the printing duration (Activity F) by 5 days ensures the schedule stays on track.

Expediting other activities like manufacturing or packaging would not directly compensate for the proofing delay.

 Cross-Verification:

Option A: Incorrect. Delaying product release impacts availability.

Option B: Incorrect. Packaging is not a direct predecessor of the product release.

Option D: Incorrect. Delaying manufacturing has no impact on proofing.

Option C: Correct. Expedites the critical path by compensating for the delay.
