In recent decades the composition of the population has changed and is becoming more diverse. According to the ABS (2012), 26% of the Australian population was born overseas and 20% of people had at least one parent born overseas. It leads to a new business environment and a diverse workforce. Therefore, it is necessary to become aware of the concept of diversity to achieve good performance by managing a diverse workforce. This essay examines the concept of diversity by summarizing several articles. There are similarities between diversity values ​​and diversity measurement differences between different articles. In both articles, diversity values ​​are identified as an essential element that determines organizational performance. In the main article, diversity is a useful attribute for decision making, while ignoring ethnic and other diversity poses a risk to an organization, including discrimination and conflict. Furthermore, Edewor and Aluko (2007) pose new challenges and opportunities that emerge due to diversity. Furthermore, Mba Sr (et al. 2013) stated that understanding diversity is the main condition for success. Furthermore, Martín-Alcázar (et al. 2012) illustrates that there are benefits from diversity with potential problems. Since both articles agree on the importance of diversity, diversity is significant to an organization and needs to be concerned about. However, there are no common measures of diversity between the main article and the additional article because the diversity is very complex. From the main article, Maringe (et al. 2007) analyzes the concept of diversity through narrow and broad perspectives and observable and unobservable perspectives. The narrow perspective of the concept of diversity... middle of the paper... status, gender expression, educational background, geographical location, income, marital status, parental status and work experience. The concept of diversity contains acceptance and respect, which means that it is necessary to understand that each individual is unique and recognize the differences between individuals by race, ethnicity, gender, sexual orientation, socioeconomic status, age, physical abilities, religious beliefs, beliefs policies or other ideologies (Jack, cited in Mba Sr & Teresa 2013). To conclude, diversity is a complex concept that cannot result in a common measurement from these articles. Both articles, however, affirm the value of diversity determining the success of an organization. Therefore, although it is complex, it is also considerable because good diversity management can cultivate and maintain a positive work environment..
