The PMBOK v5 is a highly structured standard. In order to pass the Project Management Institute's PMP exam you must know the PMBOK well. More than anything else, you must understand the structure of the concepts the PMBOK presents.
However, the PMBOK in paper or PDF form is not easy to navigate. To follow the connections between concepts you must spend too much time flipping pages and using the index and table of contents. We felt there had to be a better way.
Standardmethod.net maps all the concepts together. This database is the foundation that enables you to more easily see the flow of information from process to process, skill to skill.
