Why has the council manager form of city government replaced the mayor council form in many cities?

The council-manager form of city government has replaced the mayor-council form in many cities due to its emphasis on professional management and efficiency. This structure separates political leadership from administrative functions, allowing trained professionals to handle day-to-day operations. Additionally, it promotes a more collaborative decision-making process among elected officials, which can lead to more consistent and effective governance. As a result, many cities have adopted this model to enhance accountability and improve service delivery.
