To encourage success for everyone involved in an internship program, a manager should prioritize making the experience inclusive and rewarding for all parties. Developing a clear plan with defined objectives, providing multiple points of support such as mentorship and buddy assignments, and creating detailed, goal-oriented internship projects can help achieve this. By doing so, managers can integrate interns into their team's workflow, ensure they receive proper training and guidance, and ultimately retain them after the internship period. The benefits of internships include increased retention rates, improved career development opportunities, and a more diverse and skilled workforce.
