In CERTON’s model of the process flow in developing safety-critical software or electronic hardware, Independent Verification and Validation (IV&V) begins as the high-level requirements are created and encompasses activities during the entire life-cycle. This is key to successfully managing the risk on any safety-critical program. Our engineers have extensive experience and a powerful proprietary tool set to perform independent verification and validation test activities for requirements-based design projects.
CERTON, a Cyient company, specializes in planning and executing verification activities on a tight schedule and to a fixed budget. Our focus on automation of time-consuming verification activities means that our verification efforts are cost and schedule-resilient against changes in requirements, new baselines, and new design versions.
Independent verification and validation is essential to the development and delivery of a quality product that is safe and reliable. The concept of independence has incredible value, regardless of whether it’s necessary according to guidelines. If one is responsible for creating an output, then another should check that the output meets the original intent and is correct. Validation is very different from Verification and in order produce a safe product you need to understand the difference and perform both activities.
Validation – Correct Product???
When developing safety-critical products it is necessary to provide assurance that the correct product is being built according to the defining customer requirements and specifications. This process involves capturing requirements to describe the product functionality and design implementation. These requirements should trace to the customer requirements or they may be derived. All of the functional and design requirements need to be validated against the customer requirements and specifications through traceability, reviews, simulation, system testing, and other methods.
CERTON specializes in the validation activities with a focus on “good” requirements to meet all of the objectives for safety-critical design safety assurance. CertSAFE™ has been designed specifically to support meeting the DO-178 objectives identified in Tables A-2 through A-7 for the highest levels of safety criticality.
Verification – Product Correct???
When developing safety-critical products it is necessary to provide assurance the product is correct according to the validated functional and design requirements and specifications. This process involves developing test cases and procedures to verify the implementation (source code/executable code) is c
