What is the difference between Validation & Verification

Verification is a Quality Control process that is used to evaluate
whether or not a product, service, or system complies with
regulations, specifications, or conditions imposed at the start of a
development phase. Verification can be in development, scale-up, or
production. This is often an internal process.

Validation is Quality assurance process of establishing evidence
that provides a high degree of assurance that a product, service, or
system accomplishes its intended requirements. This often involves
acceptance of fitness for purpose with end users and other product
stakeholders.
