Walking into a new project team on day one can be an instinctive experience. Long before a project brief hits your desk or a stakeholder meeting gets underway, the atmosphere says more than words ever could. These are not just vibes — they are early warning signs of how a team is functioning under the surface.

Sometimes, you step into a room and feel it instantly; a tension that clings to every interaction. Conversations are transactional. Eye contact is minimal. There’s a quiet urgency that hums beneath the surface, not the energising kind, but the kind that feels like people are trying to outrun failure. Whiteboards gather dust. Laughter is absent. People leave right on the dot, not because they’re disciplined, but because they’re done.

Other times, you walk into a space and feel like you’ve entered a different world. The air hums with collaboration. There’s flow. There’s ease. People laugh. Challenge each other. They share ideas in real-time, often scribbling furiously on whiteboards. Their vibe is not chaotic but rhythmic, like a jazz band that knows how to improvise without losing harmony.

That first five-minute impression? It matters.

The weather system of a team

The simplest way I describe this to project sponsors and team leads is through a metaphor I call the Project Weather Report. Like stepping outside to check the weather, the team’s emotional climate can usually be assessed at a glance:

  • Sunny: Laughter, energy, flow. People are focused but not frantic. Collaboration is natural.
  • Overcast: Everyone’s present, but hesitant. There’s activity but it lacks spark or direction.
  • Foggy: No one’s really sure what’s happening. Confusion reigns. Silence lingers.
  • Stormy: Conflict is in the air. Blame, sarcasm, or visible frustration dominate.

These are intuitive labels, but they unlock important leadership insight: the team’s climate is a mirror. It reflects how people feel about their purpose, progress, and each other.

Culture is the unspoken code

Team vibe is not about personalities or perks. It’s about patterns — how people relate, resolve, and recover. What gets celebrated? What gets swept under the rug? Where is energy being invested, and where is it being drained?

As authors Gruenter & Whitaker put it: “The culture of any organisation is shaped by the worst behaviour the leader is willing to tolerate.” If eyerolls go unchecked, if sarcasm is the norm, or if disengagement is met with silence, that becomes part of the team’s DNA. Culture is set by what’s allowed to continue.

You can’t shift what you don’t sense

Before you diagnose a team with underperformance or lack of capability, tune into what you’re picking up emotionally and relationally.

When I walk into a team, I do five things:

  1. Observe without interrupting. Don’t fill the space. Read it.
  2. Notice your own reaction. Is your posture relaxing or tightening?
  3. Scan the room. Are people engaged or guarded? Are whiteboards alive or empty?
  4. Name the climate. Sunny, foggy, stormy? Get language around it.
  5. Decide your impact. Do you need to bring warmth, energy, calm, or clarity?

The goal isn’t to label and judge — it’s to lead with insight. To shift the energy of a space, you need to meet it first.

From intuition to action

I once walked into a project team where the silence was louder than any meeting agenda. People avoided eye contact. The whiteboard hadn’t been touched in weeks. No one asked me a question. I didn’t need to run a workshop to know that trust was low, collaboration was stalled, and psychological safety was missing.

Contrast that with another project, in a different organisation, where I was greeted with curiosity. Within ten minutes, I was invited into a conversation about priorities and pain points. The whiteboards were full of diagrams, timelines, scribbled risks, and stickies. The project wasn’t without problems — but the team culture made space to face those problems together.

Same deadlines. Same pressure. Different outcomes.

Why this matters for project success

Culture is the operating system of your project. It impacts how decisions are made, how conflict is handled, and how momentum is sustained.

If you’re responsible for delivery, and especially if you’re leading people through complexity, remember success doesn’t just live in your milestones. It lives in the moments in between — the hallway chats, the tone of meetings, the energy at 4pm on a Thursday.

Because in project leadership, how the team feels often determines how the project functions.
