It would be SO beneficial for my current company and all companies I worked for in Workfront if there was an asset/deliverable/product object just like statuses/companies/priorities/etc.
Overall, just like when you want to customize something like statuses it would be great to make your deliverables set objects that can be customized by group. The way I have also done this was more with custom fields, but with custom fields you lose the opportunity of attaching one object to another automatically.
For example, it would be amazing if you can create a deliverable object and directly tie it to the template object. So, if I chose a template to use or a deliverable, it would automatically pull in the other. So if I check an Infographic as a deliverable object while creating project, it would automatically pull in an infographic template.
This would also allow for some pretty slick reporting too!
There's just so much more I didn't mention here that can be done if Deliverables were their own object.
