After decades of observation and organizational consulting, here are Larman's Laws of Organizational Behavior. These are observations rather than laws to follow ;)
Elaboration on law 5: A longer form is, In big established groups, culture/behavior/mindset follows changes in the organizational system and design. That is, if you want to really change culture, you have to start with changing the organizational system (groups, teams, roles and responsibilities, hierarchies, career paths, policies, measurement and reward mechanisms, etc), because culture does not really change otherwise. Said another way, the organizational system is strongly influential on mindset and behavior.
The systems-thinking advocate John Seddon also observed this: "Attempting to change an organization’s culture is a folly, it always fails. Peoples’ behavior (the culture) is a product of the system; when you change the system peoples’ behavior changes."
This is an observation in big established organizations; in contrast, in small start ups, it's the reverse: structure follows culture. That is, the (probably simple and informal) organizational design reflects the mindset and culture of the small number of members in the start up. As the organization grows, at some point it usually reverses to culture follows structure.
And "culture follows structure" (in large groups) is why purely “mindset” approaches such as organizational learning are not very sticky or impactful by themselves in large groups, and why frameworks such as Scrum (that have a strong focus on structural change at the start) tend to more quickly impact culture — if the structural change implications of Scrum are actually realized.
