The correct answer is C — Use retrospective techniques such as silent writing, clustering, and dot voting to field feedback prior to discussion by the team.
Agile retrospectives should foster psychological safety and equal participation. Techniques such as silent brainstorming or writing on sticky notes (physical or digital), followed by clustering similar themes and dot voting, help balance group dynamics and encourage input from all team members—including those who are less vocal.
PMI Agile Practice Guide explains:
“Effective retrospectives use facilitation techniques such as silent brainstorming, dot voting, and clustering to gather inputs from all participants. These techniques level the playing field, reduce groupthink, and support diverse communication styles.”
(PMI Agile Practice Guide, Section 5.8 – Retrospectives)
Mike Griffiths also emphasizes:
“Using structured techniques allows quieter team members to contribute equally, and minimizes the dominance of more outspoken participants. The Scrum Master plays a key role in facilitating inclusive discussions.”
(PMI-ACP Exam Prep, Chapter 4 – Team Performance)
Incorrect options:
A and D are passive methods that reduce the collaborative and iterative nature of retrospectives.
B may help, but does not address dominant voices or structure participation equitably.
