- 01GDP / GMPEU GMP Annex 15: the qualification stages explainedAnnex 15 sets URS, DQ, FAT/SAT, IQ, OQ and PQ as a sequence that builds evidence a system is fit for its intended use, with requalification after changes.3 min
- 02ValidationWriting a user requirements specification for temperature-controlled equipmentThe URS states what the equipment must do in measurable terms. Every later test traces back to it, so vague requirements produce untestable qualifications.3 min
- 03ValidationDesign qualification: catching problems before installationDQ documents that the chosen design meets the URS. It is cheapest place to fix a cold room with a door on the wrong wall.3 min

- 05ValidationHow to structure a qualification protocolA protocol says what will be tested, how, by whom, and what result counts as a pass — all approved before execution begins.3 min
- 06ValidationQualifying a stability or climatic chamberChambers are qualified for temperature and humidity uniformity, stability and recovery — with acceptance criteria tied to the ICH conditions they will run.4 min
- 07ValidationHandling deviations during qualificationA test that fails or cannot be executed as written is a deviation. Record it, assess it, decide, and let the report show the whole story.3 min
- 08ValidationRequalification and periodic reviewQualified status is not permanent. Change control, periodic review and monitoring data together decide when a system must be requalified.3 min
- 09ValidationValidating the software that analyses your monitoring and mapping dataCalculations that decide whether a space passed must themselves be verified — with known datasets, expected results and a record of the software version.3 min
