Visual Comparison of Waterfall & Spiral Model

Man-Chie Tse

Middlesex University

Visual comparison can aid managers in the decision making process. The study provides a comparative analysis and evaluation discussed in the light of two software development life cycle (SDLC) models - Waterfall and Spiral using a Composite Feature Diagramming (CFD) framework developed by Georgiadou (2003). As a benchmark control, one researched the characteristics of an “ideal” SDLC model. Each model were mapped accordingly, highlighting the present attributes which indicated the absent ones. Both models still incurs criticism caused by lack of explicit requirements from today’s constant agile changes. Expert respondents ranked using a five point likert-scale of importance to measure attribute opinion. The scores determined the overall “strength” of each sub-characteristic.

As a supporting method, the final results were plotted into a Kiviat diagram; thresholds of 40% or 2.0 were assigned as benchmark value for each characteristic of the ideal model. The qualitative and quantitative evaluation results suggest waterfall should be rejected as the benchmark value was violated twice; and missing two of the major primary characteristics present in the “ideal” (planning and risk). Spiral model emerged to be more feasible as the threshold surpassed three times. Moreover, the illustration attempted to introduce potential benefits, capability issues and problems that arise from the models itself. Both models are neither perfect during the execution phase as there are no measurement(s) to determine the completeness for each stage. Equally important there is still much more significant work to be done.
