Computerized systems
Validation starts with the purpose of the system and the processes that depend on it.
The work may involve requirements, risk assessment, access controls, available audit trails and records, testing, deviation handling, and documentation of the conclusion.
Supplier involvement is considered according to the system and the evidence the supplier is able to provide.
Transportation and cold chain
In transportation, the design depends on the products, routes, vehicles, packaging, transit times, and environmental conditions involved.
Studies may require defining the worst case, monitoring points, acceptance criteria, and evaluation of the results obtained.
For the cold chain, the analysis also considers the stages in which the product remains in storage, is transferred, or is temporarily in transit.
Equipment and environments
Equipment and areas need to be evaluated according to the function they perform.
The work may include requirements, installation, operation, performance, calibration, maintenance, and criteria for use after relevant changes or interventions.
