Departments
Different cultures within the organisation
Every department carries its own version of the culture, and those versions do not always agree.
Organizations are rarely one culture. Sales may move fast and tolerate risk while finance prioritizes caution and process. Engineering runs on async written communication while HR still defaults to a meeting for everything. These sub-cultures are not accidents: they form around the work itself, the people who do it, and the managers who shaped them over time.
The friction between departments is often less about personalities than about incompatible cultural defaults. When two teams clash over how a project should run, they may each be acting perfectly rationally by their own norms. Understanding that the cultures differ is the first step to working across them.
Some degree of departmental variation is healthy and even necessary. The question is whether the differences are visible and navigated, or invisible and unacknowledged. Organizations that pretend to be one unified culture often just have a dominant culture that other departments quietly resist.
