The document summarizes three projects to expand the Panama Canal: the initial failed French project in the late 1800s, the successful American project that opened the canal in 1914, and the current Panamanian expansion project. It discusses lessons learned from prior projects, such as considering environmental conditions, disease control, and political issues. Modern project management practices like portfolio management, time/cost management, risk management, and quality management are contributing to the success of the current expansion, which aims to maximize economic benefits for Panama while meeting increasing shipping demands.
