A project's success is heavily dependent on the early stages of its lifecycle, including the conceptualization stage where the project's vision, scope, and objectives are defined. Lack of involvement by the manager or team during this stage can lead to a lack of clear direction, resulting in misaligned project goals and eventual failure. Similarly, commitment issues, whether from the manager or the team, can derail a project due to insufficient dedication to project tasks, leading to poor performance and failure to meet project objectives.
