Step 4: Finalize tasks and update the project plan Copy your task list from the Task Brainstorm tab and paste it to the Tasks and Timeline tab to create a finalized task list in your project plan. You should have at least 20 tasks. Be sure to keep tasks ordered, and highlight the milestones you've identified in the Task column. Add your time estimate for each task in the Duration column, and any notes you may have in the Notes column. Note: You can leave the Start/Due Date, Task Owner, and Status columns empty or fill them out with your own estimations.
