Pass rate of key projects and general projects

100% for main control projects and 80% for general projects.

Critical chain is an alternative to critical path analysis. The main characteristic that distinguishes a critical chain from a critical path is the use of (often implicit) resource dependencies. Implicit means they are not included in the project network, but must be identified by looking at the resource requirements.

Lack of search for the optimal solution - a "good enough" solution is sufficient because: there is no analytical method for finding the absolute optimal value (i.e., with the overall shortest critical chain).

With traditional project management methods, 30% of time and resource losses are typically consumed by wasteful techniques such as poor multitasking (especially task switching), student syndrome, Parkinson's Law, built-in Latency and lack of prioritization.

In project planning, a critical chain is the sequence of priority and resource-related tasks that prevent the project from being completed in a shorter time given limited resources. If resources are always available in unlimited quantities, then a project's critical chain is the same as its critical path approach.
