According to the PMBOKĀ® Guide (6th and 7th Editions), Project Integration Management includes the processes and activities to identify, define, combine, unify, and coordinate the various processes and project management activities within the Project Management Process Groups.
There are two primary, high-level documents that are the direct outputs of the first two processes in this Knowledge Area:
Project Charter: This is the output of the Develop Project Charter process. It formally authorizes the project and allows the project manager to use organizational resources.
Project Management Plan: This is the output of the Develop Project Management Plan process. It is the comprehensive document that defines how the project is executed, monitored, controlled, and closed. It integrates all subsidiary plans (scope, schedule, cost, etc.) into a cohesive whole.
Analysis of Distractors:
B, C, and D: These options contain subsidiary plans or specific project documents that belong to other specialized Knowledge Areas:
Scope Management Plan/Project Scope Statement: Part of Project Scope Management.
Communications Management Plan: Part of Project Communications Management.
Quality Management Plan: Part of Project Quality Management.
Risk Management Plan: Part of Project Risk Management.
While these subsidiary plans are eventually integrated into the Project Management Plan, they are not the primary outputs created by the Integration Management processes themselves. Only Option A lists the two " anchor " documents of Integration.
