This document discusses how to evaluate the effectiveness of combining a main task with ancillary texts. It outlines two parts to consider: 1) how each product is successful on its own from technical, aesthetic, emotive, creative, and purpose-driven perspectives, and 2) how the products combine to promote each other in a synergistic campaign that does not seem disparate but mutually dependent. When discussing success, the document advises identifying what metrics are used to measure it and relating each task's purpose to the overall business of production and promotion.
