What aspect of employee performance measures contributions to organizational success?

The focus on goal achievement and overall contribution is critical when measuring employee performance in relation to organizational success. This approach emphasizes not just the individual tasks completed but also how those tasks align with the broader objectives of the organization. When employees understand and contribute to the organization's goals, they can drive performance that supports strategic outcomes, enhancing both individual and team effectiveness.

Moreover, goal achievement encourages employees to focus on results that matter, fostering a performance-oriented culture. This ties directly to organizational metrics, such as productivity, profitability, and customer satisfaction. It highlights the importance of employees not just fulfilling their basic roles, but actively contributing to an environment where collective success is prioritized and achievable.

While other aspects like efficiency in task completion and adherence to policies are important for maintaining operations, they don't fully capture the broader impact of an employee’s contributions toward the organization’s success as effectively as focusing on goal achievement does.
