Project managers play a key role in performing integration on a project. What are the three different levels of integration?

According to the PMBOK Guide, project managers perform integration at three levels: process level (integrating project management processes), cognitive level (using knowledge, experience, and judgment), and context level (understanding the project environment and adapting accordingly). These three levels capture both the procedural and human dimensions of integration.

Complexity, understand, and change are not the defined three levels of integration described in the PMBOK Guide for project manager integration responsibilities.

Interest, insight, and leadership are general leadership attributes, not the formal three-level integration framework described in the PMBOK Guide.

Communication, knowledge, and value are important project management concepts but do not represent the three specific levels of integration as defined in the PMBOK Guide.
