What was the primary outcome of the risk taken by the individual in their career?

The primary outcome of the risk taken by the individual in their career resulting in improved team efficiency highlights the positive impact that calculated risks can have in a professional setting. When an individual decides to take a risk, they often innovate or challenge existing processes, which can lead to enhancements in how a team operates. Improved team efficiency suggests that the individual was able to streamline processes, foster better communication, or implement new tools that ultimately made the team's work more effective.

In contrast, the other options reflect less favorable outcomes. Reduced team morale implies a negative impact on team dynamics, which contradicts the notion of a successful risk. Increased project costs would suggest that the risk led to financial strain rather than improvements. Decreased project scope indicates a limitation in what the team can achieve, which would not typically be a desirable outcome of a risk taken in pursuit of advancement. Thus, the selection of improved team efficiency points to the successful result of a well-calculated risk, positively affecting the overall performance and productivity of the group.
