The objective of the 'Managing a Product Delivery' process in PRINCE2 is to ensure that the project's specialist products are delivered within the agreed tolerances. This process focuses on the acceptance, execution, and delivery of work packages, ensuring that each product meets the project's specifications and quality requirements. References: PRINCE2 7 Foundation Handbook and official training materials.

According to PRINCE2, a project should have tolerances defined for each project objective. Tolerances specify the permissible deviations in scope, time, cost, quality, risk, and benefits that are allowed before the deviation needs to be escalated to a higher authority. This is fundamental for the 'manage by exception' principle, allowing efficient use of time and resources by project management levels.References: PRINCE2 Foundation Manual

The Quality theme in PRINCE2 verifies that a project's products are fit for purpose. This theme ensures that the project delivers products that meet the requirements and standards necessary for acceptance by the customer and stakeholders, effectively supporting the achievement of the desired benefits.

The Quality Register in PRINCE2 should record all quality activities planned and executed to ensure the products are fit for purpose (1), and the roles responsible for reviewing the project's products (4). This register helps in tracking and managing the quality review process effectively.References: = PRINCE2 7 Foundation handbook and online resources

During the 'assessing issues' step, the project manager should consider the impact of alternative options for resolution. This involves evaluating different ways to address the issue, assessing their potential impacts on the project's objectives, timescales, costs, and risks, and then proposing the most appropriate solution for decision by the project board.References: = PRINCE2 7 Foundation handbook and online resources
