ITIL documentation (Ref: Service Transition Publication) includes Definite Media Library as a part of Service Knowledge Management System (SKMS).  This has always been a key debate points in training and consulting discussions for me – the reasons for the same, will be given below.

I also had an interesting Twitter interaction with Mr. Stuart Rance (one of the authors of the Service Transition publication 2011) on the same, yesterday.  Some  of the points of this discussion also will be explained along with my further views on the same.  Realized later, that the 140 character restriction of twitter was constraining the ability to explain viewpoints clearly and hence this post took shape.

Prior to getting into the specifics, let us look at some of the pointers about the DML and SKMS from ITIL, and based on my interpretation of the same:

As per ITIL 2011:

The definitive media library (DML) is the secure library which contains the master copies of all controlled software in an organization. The DML should include definitive copies of purchased software (along with licence documents or information), as well as software  developed on site. Master copies of controlled documentation for a system are also stored in the DML.  Electronic assets in the DML are held within the SKMS.

The service knowledge management system (SKMS), is concerned, as its name implies, with knowledge. Underpinning this knowledge will be a considerable quantity of data, which will also be held in the SKMS.

My interpretation of the same was like this:

  • Since DML contains some ‘information assets’ such as controlled documentation, technical information about the software etc – these should automatically become part of the larger SKMS.
  • Hence, “DML will be ‘stored’ in SKMS” is a wrong way of putting it. The information assets stored in DML will also form part of the SKMS.
  • There are other service assets / CIs stored in DML such as: Bought-in software with their media, in-house built software etc. These assets won’t really fit in the ‘data-information-knowledge’ spectrum in the SKMS context.  Such assets won’t be part of the SKMS.

Now, in my interaction with Mr. Stuart Rance, he has given me a few interesting view points on this: (more…)
