What would you do if you worked on a project for a year and it was eventually closed?

If a project was closed after a year of work, I would analyze the reasons for the closure to learn lessons and improve approaches in the future. It is important to document the achieved results and developments so they can be used in other projects. I would also suggest reallocating the team's resources and knowledge to new tasks, maintaining motivation and experience. Such experience helps better understand business priorities and adapt to changes.
