Peer Norms

A large aircraft manufacturer operated in a high-stakes environment where safety, quality, and precision mattered.

Formally, the message was exactly what you would expect: follow the process, protect safety, raise concerns, and make good decisions.

But every organization has two messages.

There is the formal message, and then there is the lived message.

The lived message is what people learn from what gets rewarded, ignored, challenged, or punished.

In this situation, the organization was under pressure to move quickly, compete, and keep the program on schedule. Over time, the informal norm appeared to shift.

The question was not only, “Is this the safest and best decision?”

It also became, “Will this slow us down?”

That’s where Peer Norms become powerful.

If people learn that raising concerns creates friction, the norm becomes staying quiet.

If people learn that speed gets praised and caution gets treated as resistance, the norm becomes movement.

If people learn that challenging a decision makes them look difficult, the norm becomes agreement.

Have you ever been in a workplace where the official message said one thing, but the informal norm said something else?

Maybe the official message was, “We want honest feedback,” but people learned not to push too hard.

Maybe the official message was, “Quality matters,” but the pressure was to get it done and move on.

Maybe the official message was, “Ask questions,” but people who asked questions were treated like they were slowing everyone down.

That is Peer Norms.

Peer Norms are the unwritten rules people learn by watching what actually happens.

And those unwritten rules can override what leaders say, what policies say, and what values statements say.

In this case, the cost was enormous.

Public reporting later connected the crisis to massive financial damage, including an estimated $21 billion in lost revenue tied to halted production. That estimate does not fully capture the reputation damage, regulatory scrutiny, customer trust, or leadership distraction that followed.

That’s why this lever matters.

When Peer Norms are shaping a performance issue, the problem may not show up as an official rule or policy. It shows up in what people actually do.

You may see people staying quiet when they should speak up.

That does not always mean they have nothing to say. It may mean they have learned that speaking up creates friction, makes them look difficult, or does not change anything.

You may see low standards become accepted.

Maybe deadlines slip and no one says much. Maybe incomplete work gets passed along. Maybe one person consistently avoids responsibility, and the group has adjusted around it instead of addressing it.

You may also see strong performers carrying more than their share because the informal norm is to protect comfort instead of address the gap.

That can create resentment. It can also train the group that underperformance will be absorbed by someone else.

Another outcome is false agreement.

People nod in the meeting, then do something different afterward. Or they agree publicly because disagreement is uncomfortable, unsafe, or pointless in that environment.

Peer Norms can also show up as resistance to change.

Sometimes people are not resisting the change itself. They are following the group rule that says, “This is how we do things here.” If the group rewards skepticism, delay, side conversations, or quiet noncompliance, the change will struggle even if the formal plan is solid.

So when you see these outcomes, don’t only ask, “Why won’t people do what we said?”

Ask the better question:

What behavior is the group actually reinforcing?

If Peer Norms may be affecting your performance issue, start by looking at what gets reinforced in the group.

Not just what leaders say they value. What actually gets approval, attention, praise, protection, or social acceptance?

Then look at what gets tolerated.

What behavior keeps happening without much consequence? Missed deadlines. Side conversations. Low follow-through. Avoiding hard conversations. Passing incomplete work to someone else. These patterns matter because tolerance teaches the group what is allowed.

Next, look at what people avoid saying out loud.

That can tell you a lot. If everyone knows there is a problem, but no one names it directly, there is probably a norm around silence, conflict avoidance, or self-protection.

Also examine who sets the informal tone.

Sometimes it is not the manager. It may be a long-tenured employee, a high performer, a loud voice, a respected peer, or someone the group does not want to challenge. Peer Norms often travel through influence, not authority.

Then look at what happens when someone does the right thing.

If someone raises a concern, challenges a weak decision, asks for clarity, or holds a standard, what happens next? Are they supported, ignored, punished, labeled difficult, or left standing alone?

That response tells people what the real norm is.

Finally, look at the gap between the official message and the lived experience.

If the official message is “speak up,” but people stay quiet, something is teaching them silence. If the official message is “quality matters,” but rushed work keeps getting accepted, something is teaching them speed. If the official message is “accountability matters,” but follow-through is optional, something is teaching them that standards are negotiable.

Peer Norms are not solved by repeating the policy louder.

They are addressed by changing what the group reinforces, tolerates, protects, and repeats.

That’s the lens I want you to use when you move into the Peer Norms section of the estimator.

OK, time to analyze Peer Norms surrounding your issue. As you answer these questions, think about the informal rules around the issue.

What does the group actually reinforce? What gets tolerated? What do people avoid saying out loud? What happens when someone raises a concern, holds a standard, or challenges the way things are being done?

This is not about blaming the team. It’s about noticing the patterns people have learned to follow.

Take a few minutes to complete only the Peer Norms section. Answer based on what is actually happening in your situation, not what the policy says should happen or what leaders hope is happening.
