Employers may use performance reviews, feedback from colleagues, and measurable outcomes to assess an employee's effectiveness in their role. Factors influencing job performance include skills, motivation, and work environment. Training programs and professional development opportunities can enhance an employee's abilities, while a supportive workplace culture can boost morale and productivity.
