Process validation sampling

Is it necessary to take an assay sample from compression and coating stages or not?
If is necessary give me the reason please or documented evidence

for validation its necessary to take these samples

In my organisation, it is not sampled and depending on finished assay
Is it acceptable?

What are samples of preparation steps and tests required

Usually, during coating process samples are pulled out for color and weight gain.
During tablet compression the samples are taken for friability, and hardness tests.
