The difference in perspectives between managers in Japan and Krista's Canadian colleagues can be attributed to the dimension of individualism in Hofstede's national culture.
Step-by-step explanation:
The dimension of Hofstede's national culture being described in this scenario is individualism. In collectivist cultures like Japan, there is a strong emphasis on the group and the benefit of the team. Individuals prioritize the needs and goals of the collective over their own personal interests.
