....by Bass et al. to derive architecture from requirements is oversimplified, and offer a tool to assist in finding an appropriate balance between conflicting quality attributes. The tool is based on the WinWin Spiral model, advocated so that all stakeholders feel there has been a positive outcome [2]. These architecture based strategies for refining requirements clearly blur any distinction between requirements and design. While software architects today are generally considered to be people who are concerned with the (technical) functionality of the system, this suggests a rethink of that ....

Based on this experience, we now report on testing a stronger set of hypotheses with more thoroughly collected data on a group of 15 WinWin requirements negotiations for a set of actual USC Library multimedia applications [6]. 1.2 Overview Section 2 describes the context of the projects, elaborating on the people, tasks, and negotiation process involved. In Section 3 we describe our major hypotheses, their observational results, and implications of our findings. Section 4 summarizes our major conclusions. 2 Project ....

The second semester started off by revisiting the LCA deliverables and continuing on to the IOC (Initial Operational Capabilities) milestone, which was due at the end of the second term. The LCA and IOC milestones and their activities are subject of a separate paper [6]. However, we will discuss the LCO milestone since it was the first milestone after the successful completion of the requirements negotiation. Thus, the deliverables of the LCO milestone were most affected by the negotiation. 2.3 People During the first semester (LCO and LCA) the student teams ....

The WinWin development model incorporates a number of basic models; the WinWin Spiral Model [2] 5] the WinWin Negotiation Model [3] COCOMO [1] and others [6]. The WinWin negotiation model (see Figure 1) and its supporting tool the WinWin System [4] are based on four artifact types: Win Conditions, Issues, Options and Agreements. Win conditions capture the stakeholder goals and concerns with respect to the new system. If a Win condition is ....
