hi Kamble

had worked on PCMM Level 4 during my summers with WIPRO-B'lore. i suggest u try n get a module fo the PCMM Manual published by Carnegie Melon...it talks about the implementation stages at all teh five levels. since PCMM is basically focused on people-its applicability 2 HR is direct. there r area/dimensions at each level/stage of the model which need 2 b addressed b4 progressing 2 the next level. areas like performance management, mentoring, coaching, motivation, n many others r described in detail in the manual.
i had worked in the area of mentoring which is a pillar at the 4th level of PCMM. designed the mentoring policies 4 the Fresh grad engineers called MY BUDDY at Wipro & also 4 the middle level managers called the ACE. have got a hard copy of the module...m not sure if u'd get that on net.

u can try n check out the websites of Wipro-they often talk of PCMM in their knowledge section ...
