Query: Challenges for New Physics in the Flavour Sector   In these proceedings I present a personal perspective of the challenges for
new physics (NP) searches in the flavour sector. Since the CKM mechanism of
flavour violation has been established to a very high precision, we know that
physics beyond the Standard Model can only contribute sub-dominantly.
Therefore, any realistic model of physics beyond the Standard Model (SM) must
respect the stringent constrains from flavour observables like $b\to s \gamma$,
$B_s\to\mu^+\mu^-$, $\Delta F=2$ processes etc., in a first step. In a second
step, it is interesting to ask the question if some deviations from the SM
predictions (like the anomalous magnetic moment of the muon or recently
observed discrepancies in tauonic $B$ decays or $B\to K^*\mu^+\mu^-$) can be
explained by a model of NP without violating bounds from other observables.
