Principle for Project Deliverables

B.

The principle that is central to the quality theme and provides an explicit understanding of what the project will create is "Focus on products," which is answer option B.

The quality theme in project management is concerned with ensuring that the project's products and deliverables meet the stakeholders' requirements and are fit for purpose. The products can be tangible or intangible, such as reports, software, hardware, or services.

The "Focus on products" principle requires that the project team identifies the quality requirements for each product and creates a plan to achieve them. The quality plan should describe the acceptance criteria, quality standards, and quality control measures for each product.

By focusing on products, the project team can ensure that they understand the stakeholders' expectations, develop products that meet their needs, and deliver them on time and within budget. This principle also helps to minimize the risks of rework, defects, and delays.

The other answer options, manage by stages, manage by exception, and learn from experience, are principles from other themes in PRINCE2, which is a project management methodology. "Manage by stages" is a principle from the "Progress" theme, which is concerned with managing the project's progress and reporting. "Manage by exception" is a principle from the "Plans" theme, which is concerned with developing and maintaining the project plan. "Learn from experience" is a principle from the "Tailoring" theme, which is concerned with adapting PRINCE2 to the project's needs and context. While these principles are important in their respective themes, they do not provide an explicit understanding of what the project will create, which is the focus of the quality theme.
