Adobe CC Post-Production Workflow (Story, Prelude etc.) I've never understood the post-production workflow Adobe has designed. 

I understand the steps from the editing stage onwards (assume this is a large enough production to require all steps):


Premiere: Ingest footage into bins, assistant edit, possible assembly edit
Premiere: Edit to picture lock-off
After Effects: VFX/Grading


Alternatively, use SpeedGrade for grading

Audition: Sound Mix
Premiere: Bring final grade, sound mix together
Media Encoder: Render project


However, I don't understand the workflow of Adobe Story, Prelude, and how they enhance the established workflow.



Update 1:

I should mention, I have done some research previously, but Adobe's site is delightfully dense and explanatory.

From Adobe's site, Prelude is described as:


  Metadata, megafast
  
  Work faster with smarter video ingest and logging.


How does this help the workflow, what does it add to the process?



Under our rules for asking questions a constructive question that "inspires answers that explain “why” and “how”" is acceptable.
Your workflow is a little off from how it is designed by Adobe.

Step 1: Adobe Story: You build your script and can break it into shots that you need to capture before you even start shooting.  This can then work as the blueprint to plan out shooting of the project.

Step 2: Adobe Prelude: I believe you can preconfigure a shot list that needs to be captured with meta data about the scenes.  Prelude can either be used for live capture or can be used to Ingest and organize footage on site during shooting.  Think of it a bit like Lightroom for Video.  It's intended to organize the shots so that they can more effectively be reviewed and pulled up during shooting and post production.

Step 3: Premiere: Rough edit, start laying out clips and getting the flow of the piece together.

Step 4/5: After Effects: any touch up or effects work that needs to be done on individual clips can be processed through After Effects and sent back to Premiere.  This could also be done before rough editing, but is probably easier after/during.  This may also include color grading or SpeedGrade may be used.

Step 4/5: Audition: basically the same thing as After Effects, but on the sound track/audio side on a clip level.

Step 6: Premiere: Once assets are finalized, final edit can occur to produce the finished timings for the video.

Step 7/8: Audition: Mastering, finish the audio and sound-tracking for the entire finished video to make sure it flows well from one clip to another.

Step 7/8: After Effects or Speed Grade: Perform final color grading to ensure the entire film flows well together.

Step 9: Media Encoder or Encore: Prepare final output format, either encoding for the web or building a DVD and/or Blueray disk for release.
