Final answer:
The piece of advice 'You don't need to celebrate completing a project, especially if it did not go well' is not recommended for closing projects or phases. Celebrations can be important for team morale even if the project had difficulties.
Step-by-step explanation:
The advice that is not recommended for closing projects or phases is: You don't need to celebrate completing a project, especially if it did not go well. Celebrating project milestones and completions can be a useful tool for team morale and acknowledgment of the team's hard work, regardless of the overall success of the project. Therefore, it is typically advised to recognize these efforts formally.
Capturing lessons learned is important throughout the project, not just at the end, so that the same mistakes are not repeated and successes can be replicated in future projects. Including tasks in the Work Breakdown Structure (WBS) for project closing ensures that all necessary closing activities are planned and executed efficiently. Finally, aligning resources to specific project closing tasks ensures a focused and organized completion of the project.
