If you imagine a project as a chain pulling a load, the strength of the chain is determined by the weakest link in the chain. The chain here represents the network of tasks from beginning to end in your project. In projects, the overall timescale is determined by the completion of the tasks on the critical path.
The weakest link is therefore the critical task that is currently holding up progress, i.e. stopping the next task in the chain to commence.
