It is well known that when two or more quantum measurements suffer from imperfections they may lose their incompatibility. For a quantum system of finite dimension d we study the incompatibility of all projective measurements subjected to white noise and loss. We derive a necessary and sufficient conditions for this set of measurements to becomes compatible in terms of their visibility and efficiency .
