Equipment & Instrument Qualification
Equipment is qualified. Processes and systems are validated. This distinction is not pedantic, it determines which lifecycle framework you apply, which regulatory requirements govern the work, and how you write and execute the documentation. Getting it right from the design phase avoids the most common qualification failures.
