LIME: A Three-Dimensional Software Performance Measurement Model for Project Management

An open model called QEST (Quality factor + Economic, Social & Technical dimensions) has been developed to handle, simultaneously and concurrently, threedimensional viewpoints of performance. This model was developed initially to represent multiple views of performance of completed projects. It originally represented a static view of projects. This paper presents an extension to this QEST model, which allows it to be used dynamically throughout a project’s life with the flexibility to represent, for example, distinct views of quality depending on the phase of the lifecycle considered. This model is referred to as the LIME (LIfecycle MEasurement) model and can accommodate a lifecycle model where each phase can have distinct relative distributions across the three viewpoints.
