For the Product Description of the chosen label design, the "Selected envelope" (Item 4) and "New company logo design" (Item 9) serve as inputs. The label design must be created to fit the physical dimensions of the envelope and must incorporate the logo. Therefore, these pre-existing items are Derivations (source products), not Composition (parts of the design itself). The "Composition" of the label design would typically include the digital design files or proofs. Items like "List of customers" (Item 6) are not included in the label design's description, as the design is a template separate from the variable data used during the later printing stage.

Quote: "Derivation: What are the source products from which this product is derived? Examples are... a design from which a product is created, or a prototype..."

AXELOS, Managing Successful Projects with PRINCE2 (6th Edition), Section 9.2 "Plans Theme - The PRINCE2 Approach".

Context: Discusses identifying products and their dependencies (derivation).

PRINCE2 Practitioner Exam Scenario (Calendar Project).

Context: Standard exam rationale distinguishes between the Project Product (Calendar Pack) where the envelope is a component (Composition), and a Specialist Product (Label Design) where the envelope is a constraint (Derivation).
