Requirements engineers who try to design sustainable systems may have to compromise when it comes to different environmental impacts. For example, compact fluorescent lamps contain mercury, a dangerous material. But these lamps also save energy. They reduce consumption at the expense of introducing toxic substances into the environment. To deal with these trade-offs, researchers have developed weighting metrics to account for every type of impact in a single assessment. However, the weights have the potential to direct the system design toward neglecting lowly weighted environmental concerns.
This study aims to clarify the effects of different weighting configurations. The project employs a mixing triangle that weights three different areas of environmental impact against each other. It then compares the effects of an application service provider to the effects of a system that uses locally hosted software. The comparison uses multiple weighting configurations.
