Validation, Qualification, and Verification procedure

My first instinct was to recommend you check ISO 9000:2015 definitions, but then I realized that ISO 9000:2015 uses qualification and verification interchangeably. Verification is commonly used in design activities to name a set of activities done to confirm that specifications were met. Meeting specifications is not a guarantee that requirements for intended use are met, that is the topic of validation: confirmation that requirements for intended use are met. Now, about qualification I have doubts about what you want to mean with it. Perhaps, qualification is the state after a verification well succeeded.
