Final answer:
Option 'd' is incorrect because while diversity can provide numerous benefits to a team's dynamics, it does not guarantee that projects will always be completed successfully and on time due to numerous influencing factors.
Step-by-step explanation:
The question pertains to the impact of diversity on team dynamics. Answering which statement is NOT true about the impact of diversity on team dynamics requires understanding both the positives and the potential challenges diversity can bring to a team environment.
While diverse teams are known for their potential to be more productive, drive constructive value creation, and have healthy debates leading to better solutions, there is no guarantee that diversity alone ensures projects will be completed successfully and on time. Many factors contribute to the successful and timely completion of projects, including management, resources, team dynamics beyond diversity, and external factors.
Therefore, the answer to the question would be 'd' - Diversity allows the team to complete projects successfully and on time. This statement is not inherently true as there are many variables that contribute to the successful and timely completion of projects.
