I created the document below which was very mush helpful to me hope everybody will be helped by this . the first column (besides serial number)states the priority of the object mentioned in the next column , the third column gives the activities to preserve the original settings and files so that things can be revert back in case of any issues , the last column actually implements the requirement mentioned in the object 


Column 
1---  Serial number 
2---  Priority of the objective
3--- Objective/issue that need to be resolved 
4--- Precautions , or the list of commands which preserve original content or gives command to revert back
5-- Actual commands to implement the hardening
