Change management plan

I believe too,but the real problem is that,what is the detailed process using in planning
Stage to create it? So what is the input, tools and technics that can be use to create it?

It is created during the Planning Process. It falls under Intergration Management Knowledge Area: It is an output of creating Project Management Plan. It contains:

Change Control Procedures
Approved Levels for Authorizing Changed
Change Control Board personnel and their duties and responsibilities
Plan how changes will be managed and controlled
Who should attend meetings
Emergency Change Process
Organizational Tools

That being said, I would say that the main inputs should be:

Enterprise Environmental Factors (Cuture and Existing Systems)
Organizational Process Assets (Procedures and Processes, historical informtation and Lessons Learned)

Tool and Techniques can include:

Expert Opinions
Meetings
Group Facilitiating Techniques

Great post Rami.

To add to your tools, i'd say that existing frameworks and previous change work be used in an organizational process/document review.

hi Rami
Thank you for the contribution; what you say is logical, but the concern is that it is regularly mentioned the change management plan in the PMBOK5; but there is not a clear process that change management plan would be the output. On page 72 which refers to develop PMP, it does not appear anywhere the creation of Change Management Plan
but I remain on your proposal, hoping that this will be clearer in future editions of PMBOK

Thanks Steven.

I've already mentioned these. They are part of the Enterprise Environmental Factors and Organizational Proccess Assets.
