Self-assessment involves analyzing oneself to identify areas for improvement and advance personal and career goals. It provides the best feedback as individuals can understand their own strengths and weaknesses without waiting for external feedback. For individuals, self-assessment examines factors like attitude, skills, relationships, and progress towards goals, while companies can self-assess operations and results to set new objectives aligned with goals. Regular self-assessment cultivates self-monitoring, self-correction, and motivation for growth. It helps individuals and organizations see opportunities to strengthen performance and maximize existing resources.
