Abstract: If $f\colon \,Z \rightarrow Z$ is a periodic homotopy equivalence ($\operatorname {id}_{Z} \simeq f^{p}$) or a homotopy idempotent ($f \simeq f^{2}$), the question arises whether this periodicity property can be achieved by a homotopy ``compatible with'' $f$. These coherence questions are answered.
