The continuum discretized coupled channels (CDCC) method is compared with the exact solution of the three-body Faddeev equations in momentum space. We present results for (i) elastic and breakup observables of d+{sup 12}C at E{sub d}=56 MeV (ii) elastic scattering of d+{sup 58}Ni at E{sub d}=80 MeV, and (iii) elastic, breakup, and transfer observables for {sup 11}Be+p at E{sub {sup 11}Be}/A=38.4 MeV. Our comparative studies show that in the first two cases, the CDCC method is a good approximation of the full three-body Faddeev solution, but for the {sup 11}Be exotic nucleus, depending on the observable or the kinematic regime, it may miss some of the dynamic three-body effects that appear through the explicit coupling to the transfer channel.
