The way you approach your goals, @Jjcb is a great approach for many reasons. Some people need more formal goals, but many just need to have a general plan in mind to move forward. Then there are those that write best by taking it day by day.
Now to reply to @Gearhouse:
When writing new material: I average between 1,000 and 3,000.
When rewriting: Anywhere from 300 and 3,000 words a day. This all depends on needs.
I am an outliner that uses general outline to map the way forward, but who lets the story dictate details, as long as it stays within the guardrails I set up.

If so, there are several visual graphing apps that can help you with flow charts and other such devises.
There are threads that list specific apps to use if you want to browse them.
Here is a good thread to look at:
