First, watch the video What is Costco Culture?.
After viewing the video, in 3-4 paragraphs describe the culture of COSTCO and how it relates to your organization. Be specific. For instance, compare and contrast the culture between your organization and COSTCOs. Is your organizations culture effective? (Why/Why not?) What kind of culture would you categorize it as?
You may want to go back and view the video from Week 2 to give you some more ideas.
Brevity on this topic is not your friend. I want YOU to create an opportunity for discussion among your classmates.
