How is IPM related to PP, PMC and RSKM

IPM (Integrated Project Management), PP (Project Planning), PMC (Project Monitoring and Control) and RSKM (Risk Management) are process areas in of CMMI which are meant for effective project management. IPM builds upon PP, PMC and RKSM but is not intended to duplicate them in any manner. The term "Project Management" in IPM may be confusing as it refers to "managing the project as per an integrated and defined process" rather than "just managing". IPM basically brings in the concept of organization-level maturity as compared to project-level maturity by requiring that the processes defined for a specific project are "tailored out of" the organization's standards processes. CMMI is meant to create, sustain and improve the process maturity from the organizational perspective and IPM assumes that projects will come and go but organizational process maturity would stay. This is what puts "defined" into managing the project. IPM also adds another dimension of stakeholder management which is important for managing the relationships a project team has with interfacing entities - other teams, management, customers, suppliers, etc. The idea is to manage the various sub-plans which describe the involvement of various stakeholders in the project and also manage the dependencies and relationships with the stakeholders for project success. This is what puts "integrated" into managing the project.
