Your action plan is where you'll log all of the tasks you need to complete for your project. You need to have a detailed plan for achieving your product and include the success criteria.
You'll be planning your project from the start to the end, all the way to the showcase. Here are some helpful tips:
Work backwards: Start at the showcase date (February 19th) and plan what you'll need to do working backwards
Use the Calendar: The Calendar on this website is there for you to be able to organise your due dates. Put those dates in your action plan so you don't forget them.
Be specific: Make sure you give details for each step of your project, including the dates when you want to have something completed.
Don't forget to include your success criteria in your action plan.
