We present a brief review of the phase diagrams of the transition metal, electron-doped BaFe2As2 systems and a comparison between them. This article also reviews the phase diagrams of hole- and isoelectronic-doped BaFe2As2, as well as BaFe2As2 under pressure. Empirical rules on the conditions necessary to induce superconductivity in this material are outlined. Evidence for multiple Lifshitz transitions in Co-doped BaFe2As2 and possible connections to superconductivity are also discussed.
