A critical parameter/requirements management process model for managing a development program for a product and an associated product structure-driven critical parameter/requirements management tool and environment is provided. In one embodiment, the process includes a product structure classification scheme, a parameter/requirements classification scheme, a parameter/requirements process and maturity model, and in-process and requirements conformance views. In one embodiment, the tool includes a user interface layer, a business layer, a data layer, and a database. The user interface layer may include a product structure feature group, an add/edit/link feature group, a manage maturity feature group, and a manage conformance feature group. The tool may be implemented as a web server accessible to user workstations operating as thin clients. The tool may be integrated with one or more other product development tools, such as a document-driven requirements management, configuration management, manufacturing/production control system, problem management, and phased product delivery process tools.

Critical parameter/requirements management process and environment

A fluid cartridge for dispensing fluid, such as liquid ink for a drop on demand ink jet printer, includes a housing that encloses a capillary chamber, and has an outlet port through the one wall of the housing into the capillary chamber. Capillary material in the capillary chamber is arranged so that it has a higher density adjacent the outlet port than away from the outlet port, to enhance the flow of the fluid toward the outlet port. The interior of the capillary chamber is structured to provide greater compression to the capillary material around the outlet port, and provide stability to retain the variable compression of the capillary material.
