Confirming Version Numbers

B.

The product that should be used to confirm the version number of all products in a particular stage is the Configuration Item Record (CIR), option D.

A Configuration Item Record is a document that contains information about a particular configuration item, including its version number, description, location, owner, and other relevant details. It is a crucial element of configuration management, which is the process of identifying, organizing, controlling, and tracking changes to hardware, software, and other components of a system or product.

The Configuration Item Record is used to confirm the version number of all products in a particular stage because it contains a complete record of all configuration items associated with a particular product or system. The CIR is updated throughout the life cycle of the configuration item, reflecting changes made to the item's design, development, testing, and deployment. As a result, it provides a comprehensive and up-to-date view of the current version number of all products associated with a particular stage.

The other options listed in the question are not suitable for confirming the version number of all products in a particular stage:

• The Issue Register, option A, is a document that tracks all issues, problems, or defects associated with a particular product or system. While it may contain information about the version number of products, it is not designed to provide a complete view of all configuration items associated with a particular stage.
• The Product Status Account, option B, is a document that provides a summary of the current status of a project, including its schedule, budget, risks, and issues. While it may contain information about the status of products and their version numbers, it is not designed to provide a complete view of all configuration items associated with a particular stage.
• The Product Description, option C, is a document that provides a high-level overview of a product, including its features, functions, and requirements. While it may contain information about the version number of the product, it is not designed to provide a complete view of all configuration items associated with a particular stage.
