Nice job with the task list! Now that you've outlined the tasks, you'll need to figure out the order of the tasks and relationships between each one. It is important to do this so that we can get this analysis and design done as quickly as possible.
As best you can, assign durations to these tasks. We have some historical data in the resource library. If you are uncertain about the time estimate, I find that it best to come up with a best, worst, and most likely time estimates. Then I add up the estimates (best + worst + (4 x most likely)) by giving more weight to the most likely and then divide by 6.
Please put all of this information into your preferred project management software package and share the file with me.
