Communication quality is the single most consistent predictor of team performance. More than individual talent, compensation structure or organisational culture, how effectively a team communicates determines how well it functions under pressure, resolves conflict and delivers results.
Research by Google's Project Aristotle — one of the most comprehensive studies of team effectiveness ever conducted — found that psychological safety, which is fundamentally a product of communication quality, was the defining variable separating high-performing teams from average ones.

Strong team communication does not happen naturally — it is designed. Managers who build communicative teams do so through deliberate structural choices. Research consistently identifies three foundational elements: clarity of expectations, regularity of feedback loops, and psychological safety to speak honestly.
Teams that communicate well have agreed, explicitly, on how they communicate. Not just which tools they use, but the standards they hold each other to: response times, escalation pathways, how disagreement is handled. Edmondson's (1999) landmark study on psychological safety found that teams with explicit behavioural norms reported significantly higher levels of interpersonal trust and willingness to raise concerns.
One of the most underused communication tools is cross-training — allowing team members to experience each other's roles and understand each other's constraints. When someone understands what their colleague actually does, they communicate with knowledge rather than assumption.
Ad hoc feedback is unreliable. The most communicative teams build feedback into their rhythm — through regular one-to-ones, structured retrospectives, and explicit mechanisms for raising concerns. Research by Heen and Stone (2014) confirms that teams with regular structured feedback cycles show significantly higher rates of performance improvement and retention.
"The quality of a team's communication in good times predicts its resilience in difficult ones."
DISC profiling reveals four distinct communication orientations: dominant (direct, task-focused), influential (expressive, relationship-focused), steady (patient, consensus-seeking) and conscientious (precise, detail-oriented). Teams lacking awareness of these differences often mistake style differences for character flaws.
At BD SELECT, our team diagnostics combine DISC profiling with 360° feedback to give managers a precise, data-driven picture of how their team communicates — and where the most impactful interventions lie.
