Final answer:
The Reflection Stage is when a project manager reflects on a project's outcomes to enhance future project performance.
Step-by-step explanation:
The project manager would ask, "Can what we learned from this project improve performance on future projects?" during the Reflection Stage of the management of a special support project. This stage involves looking back on the project to evaluate what was successful and what can be learned for future endeavors. It is a time for considering how the project outcomes can contribute to the knowledge base and inform similar projects in the future.
While Kübler-Ross's five-stage model of grief is mentioned, it relates to emotional responses rather than project management stages. The correct order for the stages of grief according to Kübler-Ross is: denial, anger, bargaining, depression, acceptance, which aligns with option 'c' in the provided choices. This model is often cited in discussions about change and loss but doesn’t directly relate to the question about project reflection.
