Validation determines whether the software meets what users need, above all for safety and quality, stressing whether it operates fit for its purpose in the environment it is meant for. A software validation plan is established, developed, performed and its results evaluated by a party independent to the extent the SIL requires, with its scope and contents agreed with the assessor where the SIL requires and a statement on the assessor's presence during testing; the plan justifies the strategy chosen (manual or automated, static or dynamic, analytical or statistical techniques) and identifies what is needed to demonstrate the adequacy of the requirements, architecture, design and component design specifications in fulfilling the system safety requirements, the validator checking that verification is complete; analysis and testing are the main activities, simulation and modelling may supplement them, measurement equipment is calibrated and tools shown suitable, and the software is exercised with the input signals of normal running, foreseeable events and unwanted conditions that call for a system response (6.3.4.1 to 6.3.4.6). The software validation report states whether the plan's objectives and criteria were met, the outcome and whether the complete software on its target hardware meets the requirements specification, the coverage of the requirements, the identity and configuration of hardware, software, equipment, calibration, simulation models, discrepancies and corrective actions, in auditable form with machine-readable results; discrepancies including detected errors are identified in a separate section and carried into the release note (6.3.4.7 to 6.3.4.14).
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
