[1][2] APDL covers the whole product lifecycle including early factors that affect the entire cycle such as development testing, input constraints and system components.
APDL provides an iterative and incremental way for a team of transdisciplinary members to approach holistic product development.
Functional Requirements (FR) completely characterize the minimum performance to be met by the design solution, product etc.
IC are specific to overall design goals and are imposed externally by CN, product users or conditions of use, such as regulations.
IC are derived from CN and then revised based on other constraints that the product has to comply with but not mentioned in the Customer Domain.
SC makes it possible to perform Design Structure Matrixes (DSM), change management, component-based cost management and impact analysis, and provides framework for capturing structural information and requirement traceability.
