Artifacts: These represent the visible elements such as processes, structures, goals, climate, dress codes, furniture, etc. An outsider can see them but may not understand why things are the way things are.
Espoused values: The values espoused by the leaders. They most often are grounded in shared assumptions (see below) of how the company should be run. If there is a significant mismatch between the leadership espoused values and this perception, the organization may be in trouble.
Assumptions: These are the actual values of the culture. They refer to the (often tacit) views of the world itself (e.g. human nature). Again, these assumptions should need to correlate at least to a certain degree to the espoused leadership values for the organization to function smoothly.
