#pmdistilled - the pmbok version change

Pmbok new version is in the horizon and will be released in Nov 2015. What is the impact of this on the PMP aspirant?. I got my pmp when the pmbok version was 2.0. Subsequently I saw 3!version changes. Some of them were cosmetic and at the same time I saw the welcoming high impact change by way of adding 'stakeholder management' knowledge area which is very relevant for the present day project trends of outsourcing, off shoring, in sourcing, distributed development etc, where one has to deal with a wider range of stakeholder spectrum. Knowledge areas have changed across versions. Surprisingly the lowest level components of inputs, tools, techniques, outputs, artifacts have not changed much. That trend make us believe that the forward compatibility trend will continue. Even if one prepares with the present version, the impact of version change will not be that great.
