Visure Solutions has introduced the IRQA Systems Engineering Template. According to the company, it is an IRQA extension that is made to tackle the challenges of increasingly complex embedded software systems. Visure added that the IRQA improves the quality and tracking of embedded system requirements through automated requirements specification and change management.

IRQA is a requirements solution that enables system and requirement engineers to improve the quality of requirements definition as an essential first step in boosting software quality, noted the company. It also allows clients to improve compliance by tracing each requirement through all stages of development and testing to validation. Visure emphasized that the solution enables companies to regain control not only of their own development, but of the regulatory processes and validation proof that is now an integral part of product development.

Applied to the Embedded Software Requirements Lifecycle, IRQA becomes the process backbone. The requirements process metamodel, including all the requirement-related artifacts, their relationships and their interactions with the users, are graphically represented, showing compliance through all stages of software development. IRQA helps standardize and enforce the requirements definition across the organization, formalize a common requirements specification structure and handle changes throughout the lifecycle. With IRQA, project collaborationwhether between various software groups or with hardware or mechanical contributorsbecomes easier as specific information can be communicated and shared both inside and outside the company, said Visure.

IRQA helps avoid pitfalls and mitigate risk at all levels, from writing better requirements and prioritizing needs to providing change impact analysis capabilities, said the company. As requirements are written, IRQA Quality Analyzer performs semantic analysis to give each requirement a quality rating based on such weaknesses as ambiguous words, conditional sentences, poor structure, implementation suggestions, overlapping requirements, inconsistent use of units and even legibility. For FMEA standards, the IRQA Systems Engineering Template includes the capability for risk assessment when performing failure modes and effects analysis. IRQA's change impact analysis ensures that midstream requirements changes don't breach the feasibility constraints or create budget overruns.

IRQA supports a wide range of development processes, including traditional V and waterfall, as well as supporting the shift toward a more iterative process. IRQA's structure also supports product families and variants, ensuring that a well-defined set of requirements will be faithfully rendered for each project without the error-prone work of recreating those requirements each time.

Eliminating the guesswork and misinterpretation for design teams increases the likelihood of delivering correct systems the first time and on budget. As well, IRQA can interoperate with most popular design, test, project, and user management tools, and it has open APIs and a Plug-in SDK for customization.
