Software reliability models are an important tool in quality management and release planning. There is a large number of different models that often have strengths in different areas. This paper proposes a model that is based on a geometric sequence of the failure rates of faults. This property of the failure process was observed in practice at Siemens among others and led to the development of the Fischer-Wagner model. It is described in detail and evaluated using standard criteria. Most importantly the model is able to perform equally well as other models in terms of its predictive validity.     «
