When to use inline validation in a form?

Which is better in field validation or outside validation?
In-field validation was not any more noticeable than messages displayed outside the fields.

Had the messages been positioned closer to the inputs, they might have performed better.
How many checkouts have live inline validation?
Now, our checkout benchmarks reveal that live inline validation has seen an explosive growth in adoption: in 2012, just 13% of checkouts had live inline validation, whereas in 2016, 60% had implemented it. This makes good sense since the general importance of live inline validation is well documented.
