Which document describes the business procedures for a specific project and changes the initial procedures?

The document that describes the business procedures for a specific project and outlines any modifications to the initial procedures is the Supplementary Conditions. This document typically accompanies the standard contract and provides additional stipulations or modifications that are specific to a given project. It addresses unique aspects of a project that may not be covered by the standard contract terms, allowing for flexibility in the management of that project.

For instance, Supplementary Conditions may specify different performance standards, regulatory requirements, or project delivery modifications that need to be adhered to beyond what is standardly laid out in the general conditions. This allows all parties involved in the project to be aware of the precise expectations and responsibilities, potentially preventing disputes related to differing interpretations of contract terms.

In contrast, other options focus on different aspects of project management: the Project Budget Plan deals primarily with financial aspects, the Project Timeline outlines the schedule for project completion, and the Project Scope Document defines the overall objectives and deliverables of the project without necessarily changing procedures. Thus, while all these documents are important for project management, only the Supplementary Conditions address the modification of initial business procedures specific to the project at hand.
