Identifying the Risks is an iterative process and looked upon continuously  which is well understood and need to be because of uncertain environment being sorrounded while executing the projects.

The point here is Checklist analysis (TT for Risk Identification, Page - 287), it says that Check list needs to be reviewed during Project Closure. and the purpose is for future projects.

Is it not something strange??

Can I know what could be intention of the PMBOK guide authors behind this?
