Not really. It's best for the project if we start with ALL Content materials in hand.
We gather Content, Plan then Design. Especially for video projects, after a certain phase we can't work backwards, as it's really just a do-over from the start.

Since each subsequent task of the project depends on the absolute final completion of the prior task, logically any change to a latter step required we "work backwards" to revise the prior step in order to complete the next.
For example in video editing, the Timeline of visual and effects is based on a flowing Narration, and if you alter the content or flow of that narration, then obviously the Timeline will need to be redone accordingly.

In essence this is called "double work" and inevitably costs the client added costs for the added time. Thus, as projects move forward thru these interdependent tasks, and where projects phases are completed quickly, then we want to avoid having to go back and revise things unless absolutely necessary.
