This question is best described through an example. Imagine you're doing a project to promote a product. You have two equally important deliverables:
- Street Advertisement
- Social Websites Advertisement
In order to complete those, you need (among other things) some promotional pictures:
1.1 Promotional Pictures
Social Websites Advertisement
2.1 Promotional Pictures
But if those promotional pictures are essentially the same, what is to be done in order to avoid repeated or overlapping deliverables?
