Some projects have one deliverable - a film, a commercial, easy.
Most projects have more than one deliverable. It might be a campaign with multiple versions and aspect ratios for different channels. If the list gets big enough we'll build a custom pipeline to output all these versions.
In our work for Keen we had tons of products in multiple color ways and several features for call out. These all had to have multiple aspect ratio outputs which resulted in literally hundreds of deliverables.
We built a custom spreadsheet based pipeline linked to our render engine that enabled us to track, revise and deliver all of these on time and on budget.
But what if you want to make new versions after delivery?
For Mountain Dew we built a custom template based system that enabled them to swap out product, setting and copy and output new versions quickly after delivery. Magic!
