Worked examples

Consumer product margin allocation

An illustrative cascade on a small consumer product. Stakeholder needs (cost, weight, durability) are translated into measurable requirements, then mapped onto a small architecture (housing, mechanism, fastener), and finally onto design parameters such as wall thickness, fastener diameter, and material grade.

The case shows how target margins on individual design parameters can be traced all the way back to the stakeholder needs that justify them.

Industrial cascade studies

Cascade studies from industrial collaborations — including an aerospace subsystem and an additive-manufactured component — will be published here as they are released. These will include de-identified matrix data and a discussion of how the cascade interacts with the existing requirements-management workflow.
