  2. Verification (spaceflight) - Wikipedia

    en.wikipedia.org/wiki/Verification_(spaceflight)

    Qualification is the formal proof that the design meets all requirements of the specification and the parameters agreed in the Interface Control Documents (ICD) requirements with adequate margin, including tolerances due to manufacturing imperfections, wear-out within specified life-time, faults, etc. The end of the qualification process is the ...

  3. Protoflight - Wikipedia

    en.wikipedia.org/wiki/Protoflight

    A protoflight approach carries a higher technical risk approach compared to a full qualification test program since it has no demonstrated life capability over the anticipated life cycle of the hardware, but is a technology development design process that utilizes higher risk tolerances, agile management practices, and quick responsiveness that ...

  4. Engineering validation test - Wikipedia

    en.wikipedia.org/wiki/Engineering_validation_test

    An engineering verification test (EVT) is performed on first engineering prototypes, to ensure that the basic unit performs to design goals and specifications. [1] Verification ensures that designs meets requirements and specification while validation ensures that created entity meets the user needs and objectives.

  5. Software requirements - Wikipedia

    en.wikipedia.org/wiki/Software_requirements

    Software requirements [1] for a system are the description of what the system should do, the service or services that it provides and the constraints on its operation. The IEEE Standard Glossary of Software Engineering Terminology defines a requirement as: [2] A condition or capability needed by a user to solve a problem or achieve an objective

  6. Model checking - Wikipedia

    en.wikipedia.org/wiki/Model_checking

    In computer science, model checking or property checking is a method for checking whether a finite-state model of a system meets a given specification (also known as correctness). This is typically associated with hardware or software systems , where the specification contains liveness requirements (such as avoidance of livelock ) as well as ...

  7. Design by contract - Wikipedia

    en.wikipedia.org/wiki/Design_by_contract

    When making calls to a supplier, a software module should not violate the supplier's preconditions. Design by contract can also facilitate code reuse, since the contract for each piece of code is fully documented. The contracts for a module can be regarded as a form of software documentation for the behavior of that module.

  8. Software prototyping - Wikipedia

    en.wikipedia.org/wiki/Software_prototyping

    Software prototyping is the activity of creating prototypes of software applications, i.e., incomplete versions of the software program being developed. It is an activity that can occur in software development and is comparable to prototyping as known from other fields, such as mechanical engineering or manufacturing .

  9. Formal methods - Wikipedia

    en.wikipedia.org/wiki/Formal_methods

    In computer science, formal methods are mathematically rigorous techniques for the specification, development, analysis, and verification of software and hardware systems. [1] The use of formal methods for software and hardware design is motivated by the expectation that, as in other engineering disciplines, performing appropriate mathematical ...
