Mike's Notes
Interesting point of view from IT Revolution authors. I agree 100% with Westrum's model of;
- Pathological (power-oriented) organizations are characterized by large amounts of fear and threat. People often hoard information or withhold it for political reasons, or distort it to make themselves look better.
- Bureaucratic (rule-oriented) organizations protect departments. Those in the department want to maintain their “turf,” insist on their own rules, and generally do things by the book—their book.
- Generative (performance-oriented) organizations focus on the mission. How do we accomplish our goal? Everything is subordinated to good performance, to doing what we are supposed to do.

Westrum’s Organizational Model in Technology Organizations
.
This post was adapted from Chapter 3 of Accelerate: the Science of Lean Software and DevOps: Building and Scaling High Performing Technology Organizations by Nicole Forsgren, PhD, Jez Humble, and Gene Kim.
It is practically a truism in DevOps circles that culture is of huge importance. However, culture is intangible; there exist many definitions and models of culture. Our challenge was to find a model of culture that was well-defined in the scientific literature, could be measured effectively, and would have predictive power in our domain. Not only did we achieve these objectives, we also discovered that it is possible to influence and improve culture by implementing DevOps practices.
Modelling and Measuring Culture
There are many approaches to modelling culture in the literature. You can choose to look at national culture—for example, what country one belongs to. You may also talk about what organizational cultural values are enacted that influence the way teams behave. And even within organizational culture, there are several ways to define and model “culture.”
According to Edgar H. Schein, organizational culture can exist at three levels in organizations: basic assumptions, values, and artifacts. At the first level, basic assumptions are formed over time as members of a group or organization make sense of relationships, events, and activities. These interpretations are the least “visible” of the levels—and are the things that we just “know,” and may find difficult to articulate, after we have been long enough in a team.
The second level of organizational culture are values, which are more “visible” to group members as these collective values and norms can be discussed and even debated by those who are aware of them. Values provide a lens through which group members view and interpret the relationships, events, and activities around them. According to a paper by Pratima Bansal, values also influence group interactions and activities by establishing social norms, which shape the actions of group members and provide contextual rules. These are quite often the “culture” we think of when we talk about the culture of a team and an organization.
The third level of organizational culture is the most visible and can be observed in artifacts. These artifacts can include written mission statements or creeds, technology, formal procedures, or even heroes and rituals, as Andrew Pettigrew states in his paper “Studying Organizational Cultures”.
Westrum’s Organizational Typology
Based on discussions in DevOps circles and the importance of “organizational culture” at the second level, we decided to select a model defined by sociologist Ron Westrum. Westrum had been researching human factors in system safety, particularly in the context of accidents in technological domains that were highly complex and risky, such as aviation and healthcare. In 1988, he developed a typology of organizational cultures:
- Pathological (power-oriented) organizations are characterized by large amounts of fear and threat. People often hoard information or withhold it for political reasons, or distort it to make themselves look better.
- Bureaucratic (rule-oriented) organizations protect departments. Those in the department want to maintain their “turf,” insist on their own rules, and generally do things by the book—their book.
- Generative (performance-oriented) organizations focus on the mission. How do we accomplish our goal? Everything is subordinated to good performance, to doing what we are supposed to do.
Westrum’s further insight was that the organizational culture predicts the way information flows through an organization. Westrum provides three characteristics of good information:
- It provides answers to the questions that the receiver needs answered.
- It is timely.
- It is presented in such a way that it can be effectively used by the receiver.
Good information flow is critical to the safe and effective operation of high-tempo and high-consequence environments, including technology organizations.
Westrum organizational typology
An additional insight from Westrum was that this definition of organizational culture predicts performance outcomes.
What the Research Shows
Culture enables information processing through three mechanisms, According to Westrum in his 2014 paper. First, in organizations with a generative culture, people collaborate more effectively and there is a higher level of trust both across the organization and up and down the hierarchy. Second, “generative culture emphasizes the mission, an emphasis that allows people involved to put aside their personal issues and also the departmental issues that are so evident in bureaucratic organizations. The mission is primary. And third, generativity encourages a ‘level playing field,’ in which hierarchy plays less of a role.”
We should emphasize that bureaucracy is not necessarily bad. As Mark Schwartz points out in The Art of Business Value, the goal of bureaucracy is to “ensure fairness by applying rules to administrative behavior. The rules would be the same for all cases—no one would receive preferential or discriminatory treatment. Not only that, but the rules would represent the best products of the accumulated knowledge of the organization: Formulated by bureaucrats who were experts in their fields, the rules would impose efficient structures and processes while guaranteeing fairness and eliminating arbitrariness.”
Westrum’s description of a rule-oriented culture is perhaps best thought of as one where following the rules is considered more important than achieving the mission—and we have worked with teams in the US Federal Government we would have no issue describing as generative, as well as startups that are clearly pathological.
What Does Westrum Organizational Culture Predict?
Westrum’s theory posits that organizations with better information flow function more effectively. According to Westrum, this type of organizational culture has several important prerequisites, which means that it is a good proxy for the characteristics described by these prerequisites.
First, a good culture requires trust and cooperation between people across the organization, so it reflects the level of collaboration and trust inside the organization.
Second, better organizational culture can indicate higher quality decision-making. In a team with this type of culture, not only is better information available for making decisions, but those decisions are more easily reversed if they turn out to be wrong because the team is more likely to be open and transparent rather than closed and hierarchical.
Finally, teams with these cultural norms are likely to do a better job with their people, since problems are more rapidly discovered and addressed.
We hypothesized that culture would predict both software delivery performance and organizational performance. We also predicted that it would lead to higher levels of job satisfaction. Both of these hypotheses proved to be true. We show these relationships in the figure below.
Consequences of Westrum’s Theory for Technology Organizations
For modern organizations that hope to thrive in the face of increasingly rapid technological and economic change, both resilience and the ability to innovate through responding to this change are essential. Our research into the application of Westrum’s theory to technology shows that these two characteristics are connected. Initially developed to predict safety outcomes, our research shows it also predicts both software delivery and organizational performance. This makes sense, because safety outcomes are performance outcomes in a healthcare setting. By extending this to technology, we expected this type of organizational culture to positively impact software delivery and organizational performance. This mirrors research performed by Google into how to create high-performing teams.
Google wanted to discover if there were any common factors among its best-performing teams. They started a two-year research project to investigate what made Google teams effective, conducting “200+ interviews with . . . employees and [looking] at more than 250 attributes of 180+ active Google teams.” They expected to find a combination of individual traits and skills that would be key ingredients of high-performing teams. What they found instead was that “who is on a team matters less than how the team members interact, structure their work, and view their contributions.” In other words, it all comes down to team dynamics.
How organizations deal with failures or accidents is particularly instructive. Pathological organizations look for a “throat to choke”: Investigations aim to find the person or persons “responsible” for the problem, and then punish or blame them. But in complex adaptive systems, accidents are almost never the fault of a single person who saw clearly what was going to happen and then ran toward it or failed to act to prevent it. Rather, accidents typically emerge from a complex interplay of contributing factors. Failure in complex systems is, like other types of behavior in such systems, emergent, according to Charles Perrow in his book Normal Accidents.
Thus, accident investigations that stop at “human error” are not just bad but dangerous. Human error should, instead, be the start of the investigation. Our goal should be to discover how we could improve information flow so that people have better or more timely information, or to find better tools to help prevent catastrophic failures following apparently mundane operations.
How Do We Change Culture?
John Shook, describing his experiences transforming the culture of the teams at the Fremont, California, car manufacturing plant that was the genesis of the Lean manufacturing movement in the US, wrote, “what my . . . experience taught me that was so powerful was that the way to change culture is not to first change how people think, but instead to start by changing how people behave—what they do.”
Thus we hypothesize that, following the theory developed by the Lean and Agile movements, implementing the practices of these movements can have an effect on culture. We set out to look at both technical and management practices, and to measure their impact on culture. Our research shows that Lean management, along with a set of other technical practices known collectively as continuous delivery, do in fact impact culture, as shown below.
You can act your way to a better culture by implementing these practices in technology organizations, just as you can in manufacturing.
