In recent years, the growing complexity of products, shorter product development lifecycles, and increasingly stringent compliance standards have led to the increase in formalized requirements in product development and testing. As engineering projects become more ambitious, their complexity increases. This complexity is fueled by both newer technology and a trend toward engineering projects that employ development teams and contractors around the world. Formalized requirements are critical to guaranteeing the complete and correct implementation of these projects’ goals.
In addition to increasing product complexity, vendors are accelerating product development, lowering development costs, and increasing quality in hopes of gaining a competitive advantage in their markets. An effective, cost-efficient quality and testing strategy must be based on clearly defined requirements. Requirements help you specify the exact functionality of a product and guarantee that it is tested correctly and completely. Requirements management tools make the process of storing and analyzing the requirements cost-efficient.
Many companies are also faced with stringent government and industry-specific compliance requirements. Certification standards such as 21 CFR Part 11, enforced by the US Food and Drug Administration, DO-178B, used for in-flight onboard software for aircraft, and CMMI, for general software development, define guidelines for developing reliable devices and software. As companies continue to expand globally, they are faced with even more compliance requirements posed by foreign entities. Both local and foreign compliance standards rely heavily on clearly defined requirements. Furthermore, compliance standards emphasize the need to prove the links between higher-level and lower-level requirements and the implementation of requirements in the product.
