Diversity plays an important role in group and team effectiveness because employees bring different experiences, perspectives, cultural backgrounds, and professional expertise into the workplace. However, diversity alone does not guarantee successful collaboration. Racism, ethnocentrism, prejudice, and implicit bias can create barriers that influence communication, trust, participation, and decision-making. This week's readings reinforced my understanding that effective leadership requires recognizing these barriers and establishing an environment where employees feel respected and valued. Johnson and Johnson (2017) address the importance of group development, interpersonal relationships, and managing differences in Chapters 9, 10, and 14. These concepts demonstrate why leaders must pay attention to how group members interact rather than focusing exclusively on organizational performance.

Racism, ethnocentrism, and prejudice can negatively influence team dynamics by encouraging stereotypes, creating divisions, and limiting opportunities for employees to contribute. Ethnocentrism, for example, may cause individuals to view their own cultural practices or communication styles as superior to those of others (Ashuro, 2021). Similarly, prejudice can influence how employees interpret a colleague's competence, professionalism, or leadership potential. These behaviors can weaken psychological safety and discourage employees from expressing different perspectives. Cissna (1984) examined research concerning group development and emphasized that groups do not necessarily develop through identical processes. His findings suggest that understanding differences in group development is more valuable than assuming every team follows the same developmental pattern. This reinforces the importance of recognizing how individual experiences and group interactions influence team effectiveness.

As a Cybersecurity Program Manager, I work with Information System Security Engineers (ISSEs) across both contractor and government civilian roles. I find that ISSEs bring diverse professional experiences, technical backgrounds, and communication styles to our cybersecurity responsibilities. One challenge I recognize in this environment is the possibility that employees with greater seniority or organizational authority may receive more attention than individuals with specialized technical knowledge. For example, a contractor might identify a significant cybersecurity vulnerability, but their recommendation could receive less consideration than a government employee's perspective because of assumptions about organizational status. Although this example does not necessarily demonstrate racism or ethnocentrism, it illustrates how workplace assumptions and unequal influence can undermine collaboration. Johnson and Johnson (2017) emphasize the importance of understanding interpersonal and group processes, particularly when differences affect participation and collective decision-making (Chapters 9–10).

I believe leaders can foster inclusive and effective teams by establishing clear expectations for respectful communication, encouraging diverse perspectives, and addressing biased behavior when it occurs (Landry, 2026). In my cybersecurity leadership role, I can apply these principles by ensuring ISSEs have equitable opportunities to contribute during technical discussions, assigning responsibilities based on demonstrated expertise, and evaluating recommendations using objective cybersecurity evidence. Leaders must also challenge organizational norms that discourage disagreement or unfairly favor certain employees. Cissna's (1984) research underscores the importance of recognizing that group development varies across teams, reinforcing the need for leaders to adapt their approaches rather than assume that a single leadership strategy will work equally well for everyone.

Ultimately, this course has reinforced my belief that effective leadership requires more than bringing diverse individuals together. As emphasized by Lanzolla et al. (2026), leaders must intentionally create conditions that promote fairness, trust, accountability, and meaningful participation. Niederhoffer et al. (2026) point out that organizations can strengthen team relationships and improve decision-making by recognizing unconscious assumptions, challenging discriminatory behavior, and encouraging constructive dialogue. These principles are especially valuable in cybersecurity operations, where different technical perspectives can help identify vulnerabilities, reduce organizational risks, and support mission readiness. Johnson and Johnson (2017) provide a foundation for understanding the importance of group processes and interpersonal effectiveness, while Cissna (1984) demonstrates why leaders must remain attentive to the unique developmental characteristics of their teams.

Diversity plays an important role in team effectiveness because individuals bring different experiences, skills, and perspectives to the workplace. However, racism, ethnocentrism, prejudice, and stereotypes can create barriers that prevent teams from working effectively. When individuals believe their background, culture, or experiences are superior to others, they may dismiss different viewpoints or make unfair assumptions about someone's abilities. Johnson and Johnson (2016) explain that stereotypes can cause people to judge others based on group membership rather than individual characteristics (pp. 444–449). These assumptions can negatively affect communication, trust, and opportunities for professional development. I believe diversity becomes a strength when team members respect one another and recognize that different perspectives can improve decision-making.

During my time in Navy aviation as a Maintenance Controller and Production Controller, I worked with Sailors from different backgrounds, ranks, and levels of experience. Our responsibilities required constant communication and coordination to ensure aircraft maintenance was completed safely and efficiently. One challenge in this type of environment is that experienced personnel may place greater value on the opinions of senior technicians while overlooking suggestions from junior Sailors. Although experience is important, rank does not always determine who has the best solution. I learned the importance of considering everyone's input, especially when troubleshooting maintenance problems or adjusting priorities. Johnson and Johnson (2016) explain that diverse groups can make better decisions because members contribute different knowledge, abilities, and perspectives (pp. 441–443). This reinforces why every Sailor should have an opportunity to contribute, regardless of rank or background.

Another important factor is how teams respond to disagreements. In aviation maintenance, differences of opinion can arise when determining which aircraft requires immediate attention or how limited personnel and resources should be assigned. These disagreements do not necessarily mean the team is ineffective. Johnson and Johnson (2016) explain that conflict can strengthen relationships and improve problem-solving when managed constructively (pp. 372–374). Similarly, Christian et al. (2017) emphasize that communication and coordination are important processes that help teams adapt to changing situations (pp. 63–65). From my perspective, leaders should encourage respectful discussions rather than allowing disagreements to become personal or dismissing ideas simply because they come from someone with less experience.

Leaders can create more inclusive teams by establishing clear expectations, encouraging participation, and holding everyone accountable to the same standards. In the military, this means evaluating Sailors based on their performance, qualifications, and willingness to contribute rather than personal assumptions. It also means recognizing when quieter team members have valuable information but may need encouragement to speak up. Johnson and Johnson (2016) emphasize that effective team building requires shared goals, individual accountability, and opportunities to develop teamwork skills (pp. 542–545). Ultimately, I believe successful leadership involves creating an environment where everyone feels respected and understands how their contributions support the mission. When leaders address bias, encourage open communication, and value different perspectives, teams are better prepared to overcome challenges and accomplish their goals.
