AT&T organizations in the nineties are challenging the previously conventional wisdom of using proprietary, internally developed tools for the requirements management of products and services. The Dynamic Object‐Oriented Requirements System (DOORS) is an enabling technology for AT&T to extend the reach of requirements management throughout projects to provide improved systems engineering integration and control. This paper documents templates for value and cost models to compare DOORS to AT&T internally developed tools. DOORS provides a path to gracefully and economically move from uncoupled or loosely coupled internal tools to an integrated environment that binds the information operated on by other functional engineering and non‐engineering disciplines. In the drive to improve competitiveness, AT&T's executive management insists that work performed in organizations add the most value at the least cost to make the corporation's products and services more competitive in quality, capabilities, timeliness, and cost. Internally developed tools have no market test to provide the information of their value and true costs. DOORS is a commercially supported product that meets such a market test.
