Test & Evaluation Flashcards
What is verification
Proof of compliance with requirements (looks at defects, meets “shall” statements)
What is validation
Degree to which a system accomplishes its intended purpose (customers and stakeholders, looks at consistency)
What are potential apporaches with validation and verification
TAID
Test (virtual, live, hybrid, constructive)(verification of a product or system using a controlled and predefined series of inputs, data, or stimuli to ensure that the product or system will produce a very specific and predefined output as specified by the requirements.)
Analysis (verification of a product or system using models, calculations and testing equipment. Used to model failure)
Inspection (nondestructive examination of a product or system using one or more of the five senses)
Demonstration (manipulation of the product or system as it is intended to be used to verify that the results are as planned or expected.)
What are the 4 types of simulation testing
Live (real operators and equiptment)
Virtual (software but interfaces with humans)
Hybrid (virtual and live)
Constructive (behaviours through computers)
What does successful V&V mean
The system is thought to be good enough for its intended purpose
What needs to be thought of when testing
How much testing can be afforded vs how much is needed
ALARP (as low as reasonably practiable)
What is testing by simulation (meaning)
The process of running a model which is a computational abstraction mimicking a system and its behaviour
When planning V&V, how do you create the success criteria needed to validate against the requirements
Derived from requirements and product architecture
When do you perform V&V
Initial development through the lifecycle
during modifications
reviewed during major upgrades
prior to disposal
