A collaboration between one brand and another subject can open up creative and commercial possibilities. Visibility is a possible outcome, but it does not describe the quality of the project on its own. It is necessary to understand what contribution the participants make and for which customer.
I propose to start from the product: skills involved, new features and relationship with the existing offer. If the collaboration only changes the name on the packaging, the added value should be explained without attributing to it innovations that have not been realized.
A hypothetical example is a small collection that combines expertise on materials and workmanship. The comparison should include development, minimum quantities, timing and assistance. The division of responsibilities and the use of content also require clear agreements and specific verifications.
The next evaluation can observe margins, customers achieved and skills acquired, distinguishing actual results and expectations. A very visible project can have high costs; a smaller one can offer useful learning. Collaboration has a concrete content when the contributions become recognizable in the proposal and the story remains consistent with what the customer receives, in addition to the notoriety of the names involved.
