Adapted from the final High-Performing Teams report, with selected outside research to support key points.

High-Performing Teams Are Built, Not Born

High-performing teams do not come together by luck. They are shaped by the culture around them, the behaviors leaders reinforce, and the skills people build to work well across differences. In today’s workplace, those differences are often both organizational and cross cultural. That is why strong team performance depends on trust, clarity, cultural awareness, and a workplace culture that people actually experience in their daily work.

RW3 CultureWizard’s 2026 research makes that connection very clear. More than 82% of respondents said organizational culture helps their teams perform at a high level. Another 82% said strong team collaboration strengthens company culture, and 82.1% said collaboration across teams is encouraged by their culture. Read together, these findings point to something important: culture and collaboration build each other. When values are clear and behaviors are reinforced, teams work better. When teams work well together, the culture becomes more visible, more credible, and more durable.

The strongest teams in the report also stand out in ways that feel very familiar to anyone who has worked on a truly effective team. They are more likely to reflect organizational values in daily behavior, more likely to collaborate across departments, more likely to value cultural differences, and more likely to create a climate of trust and psychological safety.

Trust sits at the center of this story. In the report data, 97.4% of respondents who strongly agree that their team culture encourages trust and mutual respect also say their organization’s culture helps teams perform at a high level. That is one of the strongest relationships in the study. Google’s Project Aristotle research reached a similar conclusion, highlighting psychological safety as the most important dynamic of effective teams, supported by dependability, structure, clarity, meaning, and impact.

Cross-Cultural Collaboration Is No Longer Optional

The cross-cultural findings add another layer of urgency. Global collaboration is no longer occasional for most professionals. In the report, 72.3% of respondents said they collaborate across borders daily or several times a week, and 83.5% said their role requires regular collaboration with colleagues from different national or cultural backgrounds. This matters because the challenges they report, communication style differences, decision-making differences, participation norms, role clarity, and trust without in-person interaction, are all deeply shaped by culture.

Employees themselves recognize the practical value of cultural awareness. Nearly 79% said cultural awareness improves team effectiveness. Among those on high-performing teams, that number rises to 90.6%. That finding aligns with broader research as well. McKinsey’s 2023 report, Diversity Matters Even More: The Case for Holistic Impact, found that companies in the top quartile for ethnic diversity were 39% more likely to outperform peers financially. The point is not that diversity alone guarantees results; rather, organizations that know how to work well across differences tend to be better positioned for performance.

The High-Performing Teams Don’t Just Happen report also makes the cost of cultural friction impossible to ignore. More than 40% of respondents said a cultural misunderstanding on their global team caused measurable business impact in the past 12 months, including lost time, rework, missed deadlines, damaged relationships, or lost business. Nearly 17% said the impact was significant. That moves cross-cultural effectiveness out of the category of nice to have and into the category of business discipline.

Building the Skills and Culture Teams Need to Thrive

Training matters, and depth of training matters even more. Respondents with more substantial cross-cultural training were far more likely to describe their teams as high-performing. This pattern fits the real world. Teams rarely become more culturally fluent through good intentions alone. They need a shared language, opportunities to practice, and practical guidance on how to adapt communication, interpret behavior, and work through differences constructively.

There is also a leadership lesson in all of this. SHRM has reported that toxic workplace culture costs U.S. employers $223 billion over five years, and that 58% of employees who left because of workplace culture said their manager was the main reason. Culture becomes real, or not, in day-to-day behavior. Teams feel it in how people communicate, how decisions are made, and whether respect is consistent or selective.

For leaders, the message is straightforward: if you want stronger teams, invest in the culture those teams are living inside, and in the cross-cultural skills they need every day. High performance grows where trust is reinforced, collaboration is expected, differences are understood, and values are translated into behavior. That kind of team is built with intention, and it becomes a competitive advantage over time.
