It is the most important and complex stage of the census work and therefore the tests and assessments must be clear and this stage reflects the success of the stages previous first so this stage must be evaluated in itself and here we must make sure that the preparatory work has been done through it:

Safety of packet operations in terms of:
1: Distributing the blocks correctly
2: Commitment to living limits during packet operation
3: Distribution of roles between different functional levels during packet operations
4: Comprehensiveness of packet operations
5: Dividing blocks correctly during packet operations
6: Ensure that packages are available on a pre-prepared basis
