A key step in the recommended approach to 'defining and analyzing the products' in PRINCE2 is writing a Project Product Description. This description captures the purpose, composition, derivation, and acceptance criteria of the project's main deliverable. References: PRINCE2 Foundation Training Manual; PRINCE2
2017 Foundation handbook.

Achieving the principle of 'ensuring continued business justification' involves confirming that the project remains desirable, viable, and achievable throughout its lifecycle. Adapting PRINCE2 to the project's scale of investment and the chosen delivery approach helps maintain its alignment with business justification, ensuring that the project's scale, complexity, importance, capability, and risk are proportionate to the project's objectives and environment.References: PRINCE2 7 Foundation handbook and documents on the principles of PRINCE2.
