Critical chain project management (CCPM) is designed to address several issues that can arise in project management, including:

1. Parkinson's Law: This law states that "work expands to fill the time available for its completion." In project management, this can lead to inefficiencies as tasks take longer than necessary simply because the time is available. CCPM addresses this by using buffer management instead of deadlines for individual tasks, which can help to ensure that work is completed efficiently.

2. Student Syndrome: This refers to the tendency to start tasks late, similar to how a student might put off studying until right before an exam. CCPM addresses this by scheduling tasks back-to-back without buffers in between, which encourages work to start immediately when a task becomes available.

3. Self-Protection: This refers to the tendency to add padding to task duration estimates to account for potential issues that might arise. This can lead to inflated project timelines and inefficiencies. CCPM addresses this by using a project buffer to account for uncertainties, which can help to reduce the need for individual task padding.

Therefore, the correct answers are Parkinson's law, student syndrome, and self-protection. Resource smoothing is not directly addressed by CCPM.
