Theoretical models of the gravitational-wave (GW) signals emitted by coalescing compact binaries are a fundamental part of the search strategy employed in the analysis of detector data. Consequently, drawing reliable conclusions from such GW searches highly relies on the existence of accurate waveform predictions.

In this talk I will briefly present how to obtain the GW signal of the inspiral of two black holes, which in turn can be complemented by large-scale numerical simulations of the merger and ringdown phase. Even though these waveforms are the best and most complete description of the expected signal we have today, various studies show that they fail to satisfy desirable (but most stringent) accuracy requirements. Nevertheless, there is potential benefit in combining inspiral and merger waveforms, and the remaining uncertainty can be expressed in terms of physically meaningful quantities such as the detection efficiency and the systematic bias in measuring the source parameters.
