Recently, these techniques have been supplemented with portfolio management, which looks at sets of IT projects and offers fast quantitative decision-making about continuation of IT projects. Today's networked world, though, poses challenges to these techniques. A major drawback is their inability to adequately specify the requirements for IT systems used by businesses that provide services to each other in a value web. In this paper, we analyze this problem, and propose a solution by coupling IE and portfolio management with value-based RE techniques at the business network level. We show how these techniques interrelate, and illustrate our approach with a small example. [brace not closed]
