The application of the constraint theory in project management is called key chain project management. It emphasizes project management from a systematic point of view. Different from the past, the key chain has become the focus of project management. It reduces delays through the management of buffers and improves project execution efficiency, thus solving the problems that traditional project management methods cannot solve. The common calculation methods of key chain project management buffers are introduced in detail. The buffer calculation method is improved and a new management method is proposed. The new method is validated as a valid buffer calculation method.
