We believe that culture is powerful because it enables people in an organisation to see and react to things in similar ways and do so skilfully and habitually, leaving time for deliberation about difficult change. Culture lies fundamentally in the work practices of an organisation and only secondarily in beliefs, stories, rituals, and so forth. Certain practices are critical for conveying the culture. They are practices for making decisions, celebrating, handing-off, and holding people accountable. These practices are important because they engage virtually everyone, have a bit of drama, and when done well significantly enhance operational effectiveness. Culturally, they are important because they convey the organisational mood and style of a culture, and it is the mood and style that unifies a culture. The mood tells people how things matter. For example, in a mood of reservation or trepidation, threatening things matter; in a mood of hope, working on a breakthrough matters. The style tells people how to react to what matters. A culture of reservation with a style of collegiality appeases when threatened. An aggressive style would lead to fleeing or fighting.
Good cultures are easily drawn to decay; hence it is a strategic imperative to monitor and strengthen organisational cultures and even transform them if they are in deep trouble.
