@Ivor: “Maybe we just need to get all these different perspectives in one room and get them to agree on which view is right?... They are all right "

 
Exactly. It isn’t so much a question of which view is right. They are all right. They are all different views into the same space.
 
What happens is that the domain people operate within (lets take Service management as an example) starts out being small. But over time (and the more architectural thinking you have) that domain starts sending out creepers into its surrounding context.

WHY is the question Architects ask and leads to higher and high scope and context setting.
HOW is the question Designers ask and leads to lower and lower scope and detail.
Architects look up.
Designers look down.

Service Management started as just that. How to manage services aka the (applications grouped as services).
 
But over time, people started to realise hang on - we are having problems with services that is not related to the running or management of them but in the design of them…and so Service management grew into the design of the services not just the management of them.
 
Over time, people started to realise hang on - we are having problems with services that is not related to the design, running or management of them but in the architecture of them…and so Service management grew into the architecture of the services (getting close to SOA territory now) not just the design and management of them.
 
Over time, people started to realise hang on - we are having problems with services that is not related to the architecture, design, running or management of them but in the strategy of them…and so Service management grew into the strategy of the services (getting close to IT Strategy territory now) not just the architecture, design and management of them.
 
So, Service Management grew into these other areas where, of course, it starts overlapping with other areas an confusion arises.
 
There is a graphic on the PEAF homepage (Under the heading Where does PEAF Fit?) that shows this creeping of Service Management into the design, architecture, planning and strategy layers www.PragmaticEA.com
