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:
Street Advertisement
1.1 Promotional Pictures
1.2 ...
Social Websites Advertisement
2.1 Promotional Pictures
2.2 ...
But if those promotional pictures are essentially the same, what is to be done in order to avoid repeated or overlapping deliverables?
