Underneath each node of the PMBOK Dashboard lies the ITTO (as you see in the example below):

When registered with PMWay you have access to each of the 49 ITTO dashboards as seen for process 4.1 below.

If signed up with PMWay (which is optional) you will have access Level 2: This contains all the PMBOK processes, their ITTOs, the flows between processes, the PMBOK ver 6 guide drilldown detail, and ability to create tailoring notes per process / process ITTO's.  This will facilitate you running your projects better!

Students wanting to write the PMI exams can use the PMWay Dashboard to help them with preparation.  My assistance is also bundled in as well if required.  Note: PMWay offers similar dashboards for other disciplines including PRINCE2 and PRINCE2 Agile, DSDM(AgilePM), SCRUM, ITIL, CMII etc., (zeroing into the Standards and Solutions Framework) as well as consulting advice on the best way to implement and use these for success.

NOTE:  The PMBOK is often disregarded as "Traditional Project Management" utilizing the "Waterfall" approach; yet this is simply not correct!
An excellent 40 minute video on the PMWay home page when you register explains exactly why this notion is totally untrue and misunderstood. In fact, the latest version of the PMBOK embraces Traditional, Agile, Iterative and Adaptive environments. And, while the PMBOK is primarily a Body of Knowledge, it is also a method that can accommodate full project lifecycles or project phases as its "Close Project or Phase" (process #4.7) clearly elucidates!
