Does anyone use the PMBOK guide after passing the PMP exam?

Thanks for the detailed and quick reply. I do find the ITTOs to be a great summary of different knowledge areas and processes in project management. But some of the inputs and outputs are not easy to grasp and are counter-intuitive.
e.g. Work Performance Reports and Work Performance Data are input in Monitor Risks process. But Work Performance Information is output for the same process.

In Control Procurement process, Approved Change Request is input but output is Change Request. This can be explained only with understanding of insight into built-in context.

Also Presentations are part of tools for Monitor Stakeholder engagement but not part of Manage Stakeholder Engagement. That is difficult to imagine for anybody part of regular stakeholder meetings and interactions.

Sometimes the tacit knowledge in ITTOs is complemented with explanations in the guide but other times it has been left unexplained.

Yes that is exactly my viewpoint too. We have to use PMBOK as a standard but it is not a guide like when you visit a new place and can ask her for directions. The business insight that one gains from experience has to be respected and the guide does not make the job really easy. It actually gives a window to the whole experience that can be gained in Project Management.
But if anybody asks if this guide can make a good project manager into a great project manager or at least turn a newcomer into a good project manager just by reading it then answer is a wry smile only.
