The high selectivity makes transition metal catalyzed reactions valuable for organic synthesis. Although very effective, not all of them are also efficient. This circumstance is illustrated by the small number of homogeneous metal‐catalyzed reactions that is used in industrial production processes compared to heterogeneous catalysis. Using important examples of the field, criteria and measures are discussed that can be used to evaluate the efficiency of homogeneous metal‐catalyzed processes. While the concept of atom economy shows the efficiency of a transformation only if very small amounts of catalyst are needed, turn over numbers give the efficiency of the catalyst itself.
