Timeline Tips

Build in Buffer Time

Add 10–20% buffer to each phase. Projects without buffer always run late because reality is messier than planning.

Identify the Critical Path

The critical path is the longest sequence of dependent tasks. Any delay on the critical path delays the whole project.

Use Milestones, Not Just Tasks

Milestones are completion checkpoints with binary status: done or not done. They are easier to track than "% complete" on tasks.

Track Dependencies Explicitly

Most timeline slippage comes from untracked dependencies. Explicitly list what each phase depends on — internal and external.
