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.

A cap actuation mechanism for placing a cap, movably mounted on a cap carriage of an ink jet printer maintenance station, into sealing engagement with the nozzle face of the printhead of the printer. The cap mechanism functioning in response to movement by the cap carriage which in turn is moved by printer's print cartridge carriage when it leaves a printing zone for servicing by the maintenance station.
