A project manager is managing a virtual team across the country.

A wiki is the best tool to record retrospective results for a distributed/virtual team because it provides a shared, persistent, easily editable knowledge base where outcomes can be documented and revisited. Retrospectives produce actionable items such as what went well, what didn’t, root causes/themes (e.g., production issues), and improvement experiments with owners and due dates. A wiki supports this by enabling structured pages, version history, links to incident records, and ongoing updates—helping the team track whether morale and operational stability improve over time. CompTIA Project+ includes meeting management and documentation practices (agendas, notes, action items) and recognizes collaboration tools used to capture and share project knowledge.

A presentation is typically one-way and not ideal for ongoing collaborative updates. Chat is transient and hard to curate as a long-term record; key decisions and actions get buried. Polling is useful for quick sentiment checks (which can help measure morale), but it doesn’t serve as the primary system to document discussion, decisions, and actions from the retrospective.

Therefore, to record retrospective results clearly and durably for a virtual team, the PM should use a wiki.
