TechNova Inc., a leading technology firm, has recently expanded its operations globally. With new offices established in the United States, Germany, Japan, Brazil, and South Africa, the company has formed diverse teams consisting of employees from various countries and cultural backgrounds. These teams are tasked with collaborating regularly to develop and launch new software products. However, the company has encountered several challenges in managing these global teams effectively.

Employees are often unaware of cultural differences and how these affect their interactions. Therefore, team members from different countries often struggle to build trust with each other. For example, the team from the U$.$S$.$ and the team from Brazil have experienced difficulties in establishing a strong working relationship. The U$.$S$.$ team perceives the Brazilian team as unreliable due to missed deadlines, while the Brazilian team feels that the U$.$S$.$ team is dismissive of their contributions. In addition, differences in time zones, language barriers, and communication styles contribute to misunderstandings. For instance, the Japanese team tends to communicate indirectly and use formal language, while the German team prefers direct and concise communication. These differences have led to frequent misinterpretations and confusion over project requirements and deadlines.
