Why Some Teams Thrive—and Others Struggle to Get Off the Ground

Ryan Donovan | June 18, 2025

Explore 5 real-world insights on team effectiveness—and learn how research-backed principles can help you build stronger, more aligned teams.

Too often, we judge team success by the outcomes: Did they hit their numbers? Ship the product? Retain their people? But as every HR and talent leader knows, performance on paper doesn’t tell the whole story. Sometimes, the difference between a thriving team and one that struggles comes down to what’s happening beneath the surface—how people collaborate, communicate, and respond to challenge and change.

In a recent conversation with our industrial-organizational psychologist and customer success leader, we unpacked what truly drives team effectiveness. Backed by decades of research and grounded in real-world team dynamics, these insights offer a fresh perspective on how to build high-performing teams—not just through talent, but through structure, clarity, and trust.

We explore five powerful moments from that discussion, each tied to a common challenge and actionable insight.

Here's what we'll cover:

Teams Deliver Results—Not Just People

“Work happens in individuals, but results really happen in teams. Our promises to employees and customers are fulfilled when people work together.”
— Tonya Lucas, Industrial Organizational Psychology Consultant III

Even the most talented employees can’t drive lasting business results on their own. Team-level outcomes require shared understanding, aligned goals, and trust. When people collaborate effectively, they create more than the sum of their parts.

Research shows that affect, behavior, and cognition—how people feel, act, and think in a team setting—are key to translating individual contributions into organizational results. These underlying dynamics often go unnoticed, but they’re foundational to team effectiveness.

HR leaders should consider how their organizations enable this kind of collaboration. That starts by measuring team-level dynamics and offering guidance that connects individual strengths to shared goals.

Star Performers Aren't Enough

“We used to think success came from star performers. But today, we know it’s the team—the structure, collaboration, and dynamics—that truly drive outcomes.”
— Tonya Lucas, Industrial Organizational Psychology Consultant III

Hiring a high performer is great. But putting them on a poorly structured team? That’s a recipe for frustration—and lost potential. The reality is, teams thrive when they’re built intentionally, with complementary traits, balanced communication styles, and clarity around roles.

This is where tools like talent assessments can play a critical role. They help reveal who your team members are beyond the resume—their values, preferences, and working styles. When combined with team-level insights, these tools help HR leaders design teams that click, not clash.

“Org charts used to define how work got done. Today, teams are flexible, cross-functional, and foundational to how organizations are built.”
— Tonya Lucas, Industrial Organizational Psychology Consultant III

Static team structures are out. Today’s work happens across silos, geographies, and job functions. The best organizations have embraced flexible team design—the ability to form and reform groups around evolving goals.

That means HR needs visibility into more than who reports to whom. You need to understand how teams actually function: who collaborates, where friction lives, and how structure impacts speed.

“To move fast, you have to collaborate—not just in your team, but across product, marketing, and leadership. That alignment is the new baseline.”
— Darren Phan, Associate Director of Customer Success

Speed isn't about pushing harder—it's about moving in sync. When team members share a common understanding of goals, roles, and priorities, decisions happen faster and execution becomes smoother.

This concept, known as shared mental models, is a hallmark of high-performing teams. And in cross-functional settings, alignment becomes even more critical.

HR and talent leaders can help foster this alignment by establishing common language, reinforcing team-level KPIs, and providing tools for structured goal-setting.

“Even one resistant voice or a toxic clique can slow down an entire team. You have to understand your team’s dynamics before you can improve them.”
— Darren Phan, Associate Director of Customer Success

Culture is more than perks and values. It’s how your team behaves when no one is watching. And sometimes, what you don’t see is what holds people back—unspoken tensions, unclear roles, or low psychological safety.

HR leaders can’t solve what they can’t see. That’s why it’s essential to surface hidden dynamics and give managers the tools to lead more effectively.

High-performing teams aren’t built on luck. They’re built on clarity, collaboration, and insight. If you want to improve team effectiveness in your organization, it starts with understanding what’s really happening beneath the surface—and giving your people the tools to work better together.
