The correct answer is C — Training in areas of weakness.

Velocity can be improved when the team removes skill-based bottlenecks. If some members struggle due to lack of knowledge or technical gaps, their productivity—and the team ' s velocity—will be impacted. Targeted training helps the team overcome these weaknesses and deliver more efficiently.

PMI Agile Practice Guide:

“Improving technical and team skills through training and mentoring increases team performance and agility. Learning is a continuous improvement activity that directly impacts delivery capacity.”

(PMI Agile Practice Guide, Section 6.4 – Developing People and Teams)

Mike Griffiths adds:

“Velocity is driven by team capabilities. When teams address their weakest areas—through training, pairing, or knowledge sharing—they improve quality and throughput.”

(PMI-ACP Exam Prep, Chapter 4 – Team Performance)

Other options:

A supports communication but doesn’t directly impact skill-based bottlenecks.

B helps with planning but not necessarily performance.

D describes the work cadence, not a practice that enhances velocity.
