Hi Vikas,
When Project Management processes are grouped "logically", they form
"Process Groups". Example, all the processes that occur at the
beginning of a project or a project phase are grouped into Initiating
Process Group. All planning related processes go under Planning
Process Group, and so on ...
When Project Management processes are grouped by "areas of
specialization", they form "Knowledge Areas". Example, cost
management, schedule management, quality management etc.
Makes sense?
