I recently earned the Open Group Certified TOGAF 9 Foundation and the ITIL Foundation certifications. Like others before me, I found points of integration between TOGAF and ITIL. However, I found it difficult to define the points of integration.
Here are a few resources that I recommend. Also, I recommend that readers keep in mind that authors often build upon the works of those who came before them.
|White Paper||This white paper describes the development of TOGAF (The Open Group Architecture Framework) and ITIL® as a background to discussions about the potential overlap in the
processes they both describe. It does not describe the models themselves.
|Webinar||Traditionally, ITIL and TOGAF professionals have been part of different teams within an organization. Due to the ongoing alignment of business and IT, these professionals now often find themselves on the same team. Because of this crossover, there is a growing trend towards organization of work based on multiple best practice models.||Aug, 2013|

|SlideShare||This slide deck attempts to offer some concrete guidance on how Architectural activities and outputs can be integrated into the ITIL framework. The focus is on integrating into ITIL processes.||Sept, 2014|
Most of the time, I see an image showing the relationship like the one below. You can see the image in the first White Paper that I listed above. It shows a dividing line between ITIL and TOGAF as they cross domains and roles. The image implies that there is no overlap. This is because of the perspective. That is, ITIL was developed to support Service Management and TOGAF was developed to support organizations in the development of Enterprise Architecture. The focus of ITIL is therefore on services, whereas TOGAF is focused on architecture. Thus, the perspectives are different. The definition of perspective is a “point of view”. ITIL and TOGAF view business and information technology from different points of view. Thus, it is difficult to find overlap because of this difference.
I have also seen an image that shows more detail about the domains and implies overlap. This image describes the scope of ITIL and TOGAF. It implies some overlap. I understand that it is high-level; but I still want more details. The first White Paper and the Webinar includes the image below.
The following image provides specific points of overlap or connections. The Webinar includes the image below.
The Webinar seems to focus on a progression from enterprise architecture to solution design. This is one way to look at the relationship – and I do not think it is wrong. However, it seems to imply that there is a separation.
This SlideShare presentation provides a similar analysis as above; but it goes much further. Below is the primary view of TOGAF and ITIL provided by the author. The SlideShare presentation provides specific details where there is overlap between TOGAF and ITIL. This is what I felt was missing in previous analysis. I cannot do justice to explaining the detail provided in the presentation. It is quite extensive and well-thought out. Honestly, I have to keep coming back and reviewing the content to understand it.
There are well-defined points of integration or overlap between TOGAF and ITIL. There was an evolution of thought over this relationship. The SlideShare presentation summarizes this evolution and provides an excellent and detailed explanation of the integration or overlap. Of course, the new problem is when do you use TOGAF or ITIL? Perhaps both at times? Or perhaps it does not matter?
The next topic that I am pondering is agile enterprise architecture.
