Developing safety-critical products can involve a considerable amount of additional work, as compliance with the legal requirements demanded by the target market must be demonstrated in an approval process before the product can be launched to that market. To successfully pass this certification, a whole series of additional, safety-related requirements must be met. These requirements usually relate to the features or capabilities of the product and also include prescriptions for the design, development and testing process. Compliance with all requirements must be seamlessly demonstrated during the certification process.
