Which of the following is utilized by companies to maximize the use of available skills in assigning jobs?

The training matrix or database serves as an essential tool for companies aiming to maximize the use of available skills when assigning jobs. This matrix provides a visual representation of employees' skills, competencies, and qualifications, allowing managers to make informed decisions about job assignments. By mapping out who is qualified to perform which tasks, the organization can effectively assign roles that align with employees' strengths. This not only enhances productivity but also fosters employee development by ensuring that team members are placed in positions where they can succeed and contribute the most.

In contrast, while a job rotation plan could also help with skill utilization by exposing employees to different roles, it is less focused on maximizing specific skills for assignments. An employee feedback system encourages communication but does not directly impact skill assessment for job assignments. Similarly, performance appraisals evaluate past performance rather than actively facilitating the optimal use of skills in current job assignments, making the training matrix or database the most relevant tool in this context.
