Information Flow: The Hidden Driver of Engineering Culture

In this episode of the InfoQ Engineering Culture Podcast, Shane Hastie speaks with Adrian Peryer about Ron Westrum's organizational culture continuum, the role of information flow in shaping team culture, and how leaders can develop requisite imagination to detect weak signals.

Westrum's Three Culture Types

Ron Westrum, a sociologist who studied organizations and culture, identified three distinct types of organizational cultures based on how information flows:

Pathological cultures hoard information and use it as a weapon. In these environments, bad news is punished, people are scapegoated when things go wrong, and there's an atmosphere of fear and threat. People actively avoid knowing things they might be held responsible for.

Bureaucratic cultures have official channels and rules about information sharing. When problems occur, the response is typically to hold inquiries and seek justice—finding who was to blame. People protect their turf and may engage in PR to spin narratives.

Generative cultures prioritize performance and mission. Everyone focuses on making sure the right person has the right information at the right time. When things go wrong, the response is collaborative problem-solving rather than blame assignment.

The fundamental distinction between these cultures is information flow. Westrum discovered that wherever he tested this framework, it held true—the way organizations handle information creates their culture.

Recognizing Your Culture as a Leader

Most teams rate their own culture as generative, describing environments where information flows freely, trust exists, and collaboration happens naturally. However, when asked where problems exist, they typically point to other teams or departments.

This pattern reveals something important: the hardest cultural work happens between teams, not within them. Small units tend to be naturally generative because people figure out that collaboration is the most effective way to behave. Startups exemplify this—everyone focuses on the mission, works long hours, but it doesn't feel burdensome because the purpose is clear.

As organizations scale and specialize, silos emerge. Finance teams, marketing teams, and engineering teams develop their own priorities and information flows. This is where culture can degrade from generative toward bureaucratic.

Building Stronger Cross-Team Relationships

Leaders need to examine both their internal team dynamics and external relationships. Within their team, they should ask: How is information flowing? How collaborative is the culture? Do people feel they have the right capacity and capability?

Beyond their team, leaders need to consider upstream and downstream relationships. Who are they serving? Who's serving them? How are those information flows working?

The most important actions leaders can take include:

• Building stronger relationships between people across teams
• Thinking about information as a product, not just a byproduct
• Being thoughtful about who produces information, who consumes it, and how it's made available
• Mapping information flows visually to identify problems

Weak Signals and Requisite Imagination

One of Westrum's less well-known but crucial concepts is "requisite imagination"—the ability to sense weak signals and imagine multiple possible futures. Generative organizations have stronger requisite imagination because people are sensitive to what might go wrong.

This manifests in several ways:

• People notice anomalies and don't dismiss them with "that doesn't work that way"
• Leaders never close down potential weak signals, even if there's no strong evidence
• There's trust in gut instincts when something feels off
• Regular pauses for reflection help surface what busy day-to-day work obscures

Requisite imagination is particularly important for safety. Organizations with the lowest accident rates are those where people actively think about possibilities and weak signals. They're not just focused on what's happening now, but on what could happen.

Making Time to Pause and Reflect

In our busy, pressured world, finding time for reflection is challenging but essential. Simple practices can help:

• After-action reviews asking "what went well?" and "even better if..."
• Daily or weekly pauses to check in with the team
• Creating space to discuss uneasy feelings or anomalies
• Trusting gut instincts when balanced and thoughtful

These small investments of time can yield substantial returns by catching problems early and improving information flow.

Why Culture Is Hard to Talk About

Culture is difficult to measure because it's the environment we're immersed in—like the envelope around us. As technologists, we often want easy metrics, but culture doesn't work that way.

However, there are frameworks that can help, including Westrum's model. Leaders should approach culture with scientific rigor, using established frameworks rather than trying to reinvent the wheel. This is a social activity that benefits from conversation, visual mapping, and collaborative sense-making.

A telling signal: if raising the topic of organizational culture with leadership produces a negative reaction, that itself is a strong indicator that the culture needs attention.

The Path Forward

For leaders wanting to improve their organizational culture:

1. Start with your own team—examine how information flows and how people collaborate
2. Look beyond your team to identify cross-team information flow problems
3. Use frameworks like Westrum's to bring structure to cultural discussions
4. Create regular opportunities for reflection and weak signal detection
5. Trust your gut and encourage others to do the same
6. Make space for requisite imagination by pausing to consider multiple futures

The key insight is that culture isn't something that happens to us—it's something we actively shape through how we handle information, how we respond to problems, and how we create space for reflection and imagination.
