Finally, frequent prototyping throughout the development cycle allowed immediate evaluation of design solutions. Prototype builds in large numbers provided printer units to facilitate all cross-functional development, testing, and extended support activities. To meet fast-track, aggressive schedules, an organization must be willing to spend money--especially on prototypes in sufficient quantities to meet a large demand. Outstanding support by manufacturing and the model shop in this regard was crucial. Similarly, early availability of print cartridges in large quantities was essential to keeping fast-paced development activities on schedule throughout the design, implementation, and test cycles.

Acknowledgments

The success of these products can be attributed to the major development efforts and cooperation of two HP divisions: the Inkjet Components Division (ICD) in Corvallis, Oregon, and the Vancouver, Washington Division (VCD). ICD developed the color printing technology in the form of a new color cartridge containing high-resolution, plain-paper inks. VCD adapted this technology to printer products and host environments to produce total system solutions via fast-track, leveraged product development. Special assistance was also rendered by HP Laboratories and the San Diego Printer Operation (SPR).

The dedicated support, direction, and cooperation of division and functional management from ICD and VCD was a prime factor in the success of this program. Recognition and appreciation go to the program management staff, including Bob McClung, Ron Prevost, and Tom Braun. The contributions of other management staff and their respective organizations were significant, particularly those of John DiVittorio, Gary Cutler, Dan Weeks, Joe McGuckin, John Coyier, Melissa Boyd, and Bob Conder. There were also numerous individual contributors whose efforts, accomplishments, and personal sacrifices were key in this most aggressive program undertaking.
