 The project manager should have allocated additional time for mentoring the intern, as this would have helped the intern to learn faster and perform better. Mentoring is a key practice in agile projects, as it helps to transfer knowledge, skills, and experience from senior to junior team members. It also fosters collaboration, trust, and feedback within the team. By allocating more time for mentoring, the project manager could have ensured that the intern was adequately supported and prepared to take over the critical role. This would have reduced the risk of delays and quality issues in the project. References:
