(necessary for Collaboration)
The governance system had to provide a mechanism for coordination and engagement across groups including departments and spend control. This requires a mechanism of shared learning — for example, discovery and dissemination of examples of good practice. To achieve this, we must have a common language. Maps were that language.
Nobody will ever disagree that being able to efficiently communicate with the rest of the company is a good thing. page 
Yet, when was the last time you evaluated whether the rest of the company understands your team well enough?
Instead of using multiple different ways of explaining the same thing between different functions of the company then try to use one e.g. a Map.
If you’re using business process diagrams on one side and IT systems diagrams on another then you’ll end up with translation errors, misalignment and confusion.
Collaboration is important but it’s very difficult to achieve if one group is speaking Klingon and the other Elvish and let us face it, Finance is Klingon to IT and IT is generally Elvish to Finance.
This is why companies often value people skilled in multiple areas who act as translators. But a soldier doesn’t need to know how to operate a boat to work with someone from the Navy nor does a sailor need to know how to operate a mortar to work with the Army.
They use maps to collaborate and co-ordinate. The problem in business is the lack of a common language i.e. the lack of any form of mapping. If you can’t map what you are doing, then I recommend you hold back from acting and spend a few hours mapping it. page
Doctrine Assessment
* Instead of using multiple different ways of explaining the same thing between different functions of the business, we use one - a map. If you can't map what you're doing then don't do it. Situational Awareness is not optional. * A necessity for effective collaboration is a common language. Maps allow many people with different aptitudes (e.g. marketing, operations, finance and IT) to work together in order to create a common understanding. Collaboration without a common language is just noise before failure. * The governance system had to provide a mechanism for coordination and engagement across groups including departments and spend control. This requires a mechanism of shared learning – for example, discovery and dissemination of examples of good practice. To achieve this, we must have a common language. Maps were that language.
