Dear Mr.Pritesh,
Good work.You can even sub group & refine you doc as pre training needs & post training needs - You can include your guest comments in that.
You can include TRAINING NEEDS IDENTIFICATION MATRIX by adding fields such as:
1.Course (Topics)
2.Employees requring training with date.
3.Source of training (Job profile / Training agency / pre training survey from candidates)
4.Duration (Hours)
5.Frequency
6.Location if applicable
Also a simple training needs identification format is attached.
