Talent assessment and employee growth experiential learning app.
<Problem> - OJT training is left to the field and depends on the supervisor. - As a playing manager, there is not enough time to develop subordinates. - Human resource evaluations, 1-on-1 meetings, and mentor operations are not functioning well and have become mere formalities. ⇒ - Development of human resources is not progressing, and productivity is not increasing. - Future leader candidates are not being cultivated. - Employees suddenly resign. <What can be done with the Locosol experiential learning app> 1. Streamline the identification of talent (discovering potential managers and appropriately evaluating current managers). 2. The app allows for practical experiential learning. By reflecting on daily work experiences, it creates a system for employees to grow through OJT, which is completely different from traditional training. Development can be continuous rather than just point-based. 3. The thoughts and innovations of subordinates, which were previously invisible, are made visible, allowing for effective development. As an example of utilization, high-quality operations of meetings (1-on-1) and evaluation systems between supervisors and subordinates become possible.
For the peace and safety of the people.
