The correct answer to this open question is the following.
It is Will's second month at his new job and he has noticed that people dress casually every Friday. He feels that his co-workers are helpful and his bosses are friendly. He is comforted by the fact that if in doubt he can always ask for help and not be afraid of being shunned and embarrassed. Will has been influenced by observable culture.
In organizational terms, observable culture is the evidence in an organization that the core values are being applied by every member of the company. These values represent the core of the company that binds everyone in the organization. These values can be seen by all people that work in the company or any externals that visit the organization. That is why Will feels very comfortable working there. People are amicable, co-workers are willing to help, and policies are relaxed for the benefit of good working relationships.
